A-DAC AR-15 Lower from AXTS Weapons Systems

The A-DAC lower receiver for the AR-15 family of weapons is a new and interesting concept from AXTS Weapons Systems. A-DAC stands for Ambidextrous Dual Action Catch. The A-DAC lower’s unique feature is that by fully depressing the magazine release button, you also activate the bolt catch. This allows right handed shooters to activate the bolt catch with their strong hand trigger finger while also releasing the magazine.

This functionality removes several steps from the process that is necessary to clear a double feed malfunction. Normally, the shooter would lock the bolt to the rear using the bolt catch, then release the magazine using the magazine release button, and so on. The A-DACs lower allows the the shooter to lock the bolt to the rear and drop the magazine using only the magazine release button which should save time.

It should also be noted that, in the renders that I have seen, these lowers will be designed to accept the previously reviewed and excellent Battle Arms Development -Ambi Safety Selector – Short Throw.

You can find more information about the A-DAC Lower on the AXTS Weapons Systems website.

QFSS from STAT International and LMT

The QFSS is a new offset optic mounting system from STAT International and LMT.

Many rifles, like the AR-15, are capable of both tremendous accuracy and tremendous speed. However, the optics that are mounted on these rifles are usually optimized for either speed at shorter distances or long distance accuracy. This disparity between the versatile nature of the rifle and the specialized nature of the optic is very apparent when you try to use a magnified optic at shorter distances. The magnification can slow the shooter in acquiring the target enough that they are unable to achieve the full extent of the speed that the rifle is capable of.

Optics like those from Trijicon that reticles designed to utilize the Bindon Aiming Concept and optics with low power magnification settings are certainly very usable at shorter distances, but they will still never match the speed of a red dot sight (RDS). In order to deal with the short comings of magnified optics, many competition shooters began to find ways to mount a mini RDS and a magnified optic. This allowed the precision at longer distance that they required and the speed up close when they are going against the clock. It worked well enough that the concept quickly found its way to the battle field.

Originally, the RDS was mounted on top of the magnified optic which required the shooter to adjust their cheek weld in order to acquire the RDS – if a cheek weld was even possible. Lately, there are have been mounts that allow the RDS to be mounted offset from the magnified optic so that the shooter needs only to slightly rotate the rifle while maintaining their cheek weld to acquire the RDS. Since the shooter is able to maintain their cheek weld, it takes less time to acquire the mini RDS. This brings us to the QFSS from STAT International and LMT.

QFSS stands for Quick Fire Sight System. The QFSS is a mount that allows you to mount a mini RDS at a 45 degree offset to your magnified optic. It is called a system for good reason. It isn’t just a single mount. The QFSS actually contains everything needed to mount several of the most popular mini red dot sights:

  • Doctor Reflex
  • Burris Fastfire II
  • Aimpoint Micro T-1 and H-1
  • Insight MRDS
  • Trijicon RMR
  • Leupold Delta Point

I would think that this modular, all in one approach would make the QFSS very attractive to any group that might have a variety of different optics at their disposal. STAT International tells me that eventually the mount will be offered with the specific mount needed for your specific mini RDS for those who don’t need to capability to mount several different types of mini RDS.

Even though the QFSS offsets the mini RDS, it is still inline with the bore and the adapters are made to compensate for the height differences of each different mini RDS. Zeroing a mini RDS that is mounted on top of a magnified optic can be tricky due to the extreme height over bore. The QFSS will not suffer from these issues.

So, if there are other offset mounts on the market, what makes the QFSS unique? Well, the modular design is pretty unique but what is most unique is the process by which the QFSS came into existence. STAT International conducted 100 surveys, poured over the data, and tweaked the design until it worked exactly the way it should. This lead to details like the use of slotted screws which can be removed with any number of field improvised items. This 8 month R&D period produced a mount that STAT International claims will repeat zero within 1/16 to 1/8 MOA.

Review: Multitasker Series 2

The box has many of the features of the Series 2 printed on the sides.

The Series 2 is Multitasker’s version of the traditional folding pliers type multitool. I have reviewed the Multitasker Tools TUBE and Ultralight in the past and I was very impressed with their design, quality, and function. The Multitasker Series 2 tool takes that same design, quality, and function to a whole new level.

Several useful items are included with the Series 2.

In the Box

The Multitasker Series 2 comes with a number of useful items. When you open the box you will find several items: the tool itself, a sheath, 10 assorted 1/4″ screwdriver bits, a bit holder, and an instruction sheet that also spells out information about the limited lifetime warranty.

The 10 included screwdriver bits are as follows:

  1. T10 Torx
  2. T15 Torx
  3. 3/32 Hex
  4. 7/64 Hex
  5. 1/8 Hex
  6. 9/64 Hex
  7. 3/16 Hex
  8. 3/32 slotted
  9. 3/16 slotted
  10. No. 1 Phillips

The sheath is made from heavy duty ballistic nylon and seems to be very durable.

The sheath is MOLLE compatible.

The bit holder is held in place behind the Series 2 with an elastic sleeve.


The sheath is designed to accept both the Series 2 itself and the bit holder (with bits). There is an elastic sleeve in the back of the sheath that holds the bit holder in place and keeps it from rattling against the Ultralight. The back of the sheath features a MOLLE strap that allows you to attach the sheath to your chest rig, belt rig, plate carrier, pack, or any other MOLLE webbing. The sheath is very nice but I usually just end up throwing the Series 2 into a pocket on my chest rig or cargo pants.

The 2 piece bit holder holds the bits in place when in the closed position.

Bits and Bit Holder

I’ve said it before and I will say it again. The fact that Multitasker Tools use standard 1/4″ screwdriver bits is one of the best things about the tools. There are other tools on the market that use non-standard or proprietary bits which makes them far less useful to me. With a Multitasker Tool, I can walk into any hardware store and buy a screwdriver bit to customize my kit. It is convenient and inexpensive.

The bit holder that comes with the Series 2 is ingenious. It separates into two pieces to allow access to the bits and connects together for easy storage. The bit holder is made from plastic and maintains a tight friction grip on the bits to prevent loss.

The pliers are precision CNC-machined from D2 tool steel.

A precision roller bearing keeps the pliers moving smoothly.

The Pliers to End All Pliers

I will discuss the entire tool selection below, but the pliers are impressive enough to merit their own section. These pliers will blow you away.

Most users will notice the needle nose pliers first. These are the sturdiest multitool pliers that I have ever seen. The pliers are CNC-machined from D2 tool steel which makes them incredibly durable and very precise in how they fit together. They are finished with QPQ Tufftride, a nitrocarburizing treatment, which is very durable. D2 steel is not considered a stainless steel but is close. The QPQ Tufftride finish will protect the pliers from the elements.

The D2 steel will really pay off in the wire cutters which are integrated into the pliers. D2 is highly wear resistant and should deliver great cutting performance for a long time. The teeth of many multitool pliers are easily gouged and rounded over during use. This is not the case with the Series 2 thanks to the D2 tool steel.

To top it all off, the pliers pivot on a precision roller bearing. This makes the pivot point very strong and very smooth. You really have to feel how these pliers pivot to understand how smooth they feel.

The Series 2 features a wide variety of useful tools.

Other Tools

The tool selection of the Multitasker Series 2 is impressive. It is the most exhaustive tool in the Multitasker Tools line up. You will recognize several of the tools from the Ultralight review but several are unique to the Series 2.

The castle nut wrench is a great idea. The castle nut is the notched round nut that holds the end plate and receiver extension (AKA buffer tube or stock tube) in place. Ideally, the end plate should be staked to prevent the castle nut from coming loose but most manufacturers skip this step. If the castle nut comes loose, it is can lead to malfunctions. Castle nuts seem to have a knack for coming loose at the worst possible time so having a way to tighten the castle nut is a wise course of action. It should also be noted that the castle nut wrench also makes a great bottle opener.

The tanto style blade is made from 440C steel.

The liner lock engages the blade very securely.

The Series 2 has a knife with an American tanto profile. It is made from 440C steel. 440C does not get the respect that it deserves as a knife steel. It takes and holds a very good edge without being difficult to sharpen like many more modern cutlery steels. The blade has a thumb stud that allows it to be opened with one hand. It is locked in the open position with a liner lock. The blade has an over-travel stop ground into the tang to prevent the liner lock from slipping off the tang.

The file has a coarse side and a fine side. It also has a tip that is designed to be used as a flat tip screw driver. A small file is a nice thing to have on the range. I have used mine for everything from cleaning up a scarred Glock magazine well to adjusting point of impact on revolvers with fixed sights.

Users of LaRue Tactical products will appreciate the 3/8″ box wrench. It can be used to adjust the tension on LaRue mounts. I have something from LaRue on every one of my carbines so this tool sees a lot of use.

The bit driver is one of the most used tools on my Multitaskers. It comes with a very easy to use front sight adjustment tool installed but it can easily accept any of the included bits. As I said above, many multitools use non-standard sized bits, but Multitasker Tools insist on the extra function, ease of use, and versatility that comes with using standard 1/4″ bits. These bits are available inexpensively in any hardware store which makes it very easy to tailor your Multitasker to your specific carbine. You may want to consider adding an extension to your kit.

The Series 2 features a well designed bolt scraper. It has a thumb stud that allows you to open it one handed. The end of the scraper is bent 90 degrees and is rounded. This allows it to conform to the unique contours of a bolt tail. Many users have also reported success when using this tool to clear brass stuck in the chamber of their AR or correct bolt override malfunctions.

The final tool is a dental pick. The pick is shaped to be helpful in cleaning the very small corners that can be found on an AR-15 bolt. It is also shaped to be a useful for removing the bolt retainer pin from the bolt carrier. The pick can be removed from the tool to reveal a threaded post that will accept an OTIS cleaning cable. This allows you to use your Series 2 as a handle for pulling your cleaning cable through the barrel.

Details, Fit, and Finish

Every tool but the pliers are accessible without having to open the Series 2. This also means that when the Series 2 is opened to be used as pliers you aren’t gripping over all the tools which makes it more comfortable to use.

Individual backsprings and bronze washers are a mark of a well made multitool.

The textured G10 handle slabs and lanyard loop make this tool hard to lose.

Each tool has an individual cut in the backspring. This enables the tool to have consistent tension on multiple tools. Many tools with a single backspring lose tension on the tools next to the one that you are trying to open. This is not the case with the Series 2.

The lanyard loop may seem like an afterthought to some but it is extremely useful. It is a good idea to dummy cord your tool to something if you are working in the dark or near water. It is the kind of thing that you don’t appreciate until you need it.

The handles of the Series 2 are covered with G10. G10 is a laminate material that is very durable. It doesn’t absorb liquid and it is impervious to most solvents. It can be machined with an aggressive texture which makes it the ideal material to cover a tool that works in and around oil and solvents. The use of G10 on this multitool is one of the things that absolutely sets it apart from other tools. It is obvious that some thought went in to where and how this tool would be used.

The construction of this multitool is reminiscent of a high end folding knife. The Series 2 feels substantial and well made in your hand. It has a weight to it that is confidence inspiring. It makes use of D2 tool steel and 440C cutlery steel. It features G10 handle slabs. There is a precision bearing in the pliers. Bronze washers are placed between every tool to allow smooth operation while maintaining a tight fit. These are all qualities and features that you typically see on high end production and custom knives.


This may be the largest, heaviest, and most expensive Multitasker Tool of all that I have reviewed but it is also the most complete. The tool selection is extensive and functional. The materials are purposefully selected to enhance function. The construction is bomb proof. This tool is made to work hard. I don’t go to the range without it.

You can purchase your own Multitasker Series 2 at Brownells. You can also check out the Multitasker Tools Facebook page for more insight on these awesome tools.

This Multitasker Series 2 was provided to me free of charge for review.

Review: Grip Force Adapter for Glocks

The Grip Force Adapter is a bolt-on grip enhancement for Glock pistols that promises to improve the Glock’s grip. Does it deliver?

The Grip Force Adapter consists of two parts: an extended trigger housing pin and the adapter itself.

What Problem Does it Fix?

The Glock’s grip is much maligned. Two of the more common complaints with the grip are that the pronounced hump on the backstrap (the rear surface of the grip) makes the grip angle feel too swept back and that the “beaver tail” (or grip tang) does not prevent the web of your hand from coming in contact with the slide rails when the slide is in motion.

The backstrap issue hinders the ability of the user to point the gun naturally. I don’t tend to notice issues like that and have always found that aligning the sights and controlling the trigger still results in quality hits. Nevertheless, it is an issue for some shooters. Glock shooters who have this issue would generally spend money to have a “grip reduction” completed on their pistol. A grip reduction reduces or removes the hump on the back of the backstrap. Removing the hump gives the Glock a straight backstrap and a more upright grip angle. Grip reductions work but they are permanent, expensive, time consuming, and may void your warranty. Those who are issued weapons and are unable to permanently modify them in any way can’t even consider having a grip reduction done to their Glock.

If you tend to experience the “slide bite” or “race tracks” which result from the web of your hand coming in contact with the moving slide, you used to only have two  options. You could have the beaver tail extended but this has all the same downsides as the grip reduction or you could live with it.

This picture compares the G17 backstrap with and without the adapter.

How Does It Fix the Problem?

The Grip Force Adapter seeks to mitigate these issues by enhancing the grip 2 ways. It flattens the backstrap and it extends the “beaver tail” area of the grip.

It flattens the backstrap by filling in the curve above the Glock’s grip hump. The deeply curved backstrap is replaced with the flat profile of the Grip Force Adapter. This results in a fairly dramatic change in how the grip feels in your hand and changes the trigger reach surprisingly little since the Grip Force adapter is very thin.

It also covers and extends the beaver tail. This is the biggest selling point for me. I have found that it is very common for me to come home from the range with “race tracks” after working with a Glock. This is a fairly common issue for those who take a very high grip on the Glock. The beaver tail is what stands between the web of your hand and the slide rails. By extending the beaver tail you greatly reduce the chance of getting cut.

Does It Work?

The Grip Force Adapter really does deliver on its promises. The biggest benefit for me was the extended beaver tail. It is extended enough that it is virtually impossible for my hand to come into contact with the slide. I can place my grip as high as I want and not even come close to contacting the slide. This has made my range trips more comfortable.

The grip angle of the Glock has never really been an issue for me so the grip angle improvement, while dramatic, didn’t really have much of an affect on how I shoot. However, I have spoken with several other experienced shooters who are use the Grip Force Adapter and rave about the improvement. If you have always wished that Glock has a straight backstrap, this will be a marked improvement for you.


The Grip Force Adapter is made from cleanly molded plastic. The instructions say that you may want to sand the edges lightly to knock down any sharp spots but I didn’t need to do any sanding.

The trigger housing pin that is provided is extended to allow the Grip Force Adapter to hook onto it on both sides of the frame. This seems to be a very secure set up. Those that want an even more secure installation can apply some RTV silicone under the Grip Force Adapter. This provides an extra measure of security but can still be removed fairly easily to return the Glock to stock configuration.

The Grip Force Adapter's trigger housing pin is longer than the stock pin.

The texture on the Grip Force Adapter is very well executed. It is slightly sharper than the stock texture and provides very good purchase without being irritating. It reminds me of the RTF4 Glock frames (Gen4) but it is still a little sharper. If you found that it was too sharp for your tastes, you could easily sand it down until is more comfortable for you.

The Grip Force adapter is made in both black and FDE colors. There is a version available for the generation 1,2, and 3 frames and a second version that is available for the new generation 4 frames. I had the generation 1,2,3 version and found it to fit easily on several different Glocks including a generation 3 G19, a stippled generation 2 G-17, a generation 3 G35 with grip tape in place, and a generation 3 G17 with the RTF2 frame. It fit everything that I tried it on.

The adapter fits this 3rd generation G19 very well.

It also fits this generation 2 G17, even with the stippling.


The Grip Force Adapter has somewhat large rounded ridges that run vertically up the beaver tail area. These are intended to make the adapter more rigid since the plastic is quite thin. The ridges are placed side by side across the full width of the adapter. The ridges in the center of the adapter are barely noticeable but the ridges on the sides can press against the first knuckle of my strong hand which is a little irritating. This is a small gripe with an otherwise excellent product and it is a gripe that can easily be fixed with a rotary tool.

The Grip Force Adapter does slightly increase the trigger reach and for some shooters this may be an issue. I have very average hands. I usually wear a medium or large size glove depending on the brand and I had no issues at all with trigger reach. In fact, I could tell no difference at all in how I was able to place my finger on the trigger. Even my wife had no problem reaching the trigger with the Grip Force Adapter installed and her hands are smaller than mine.

The vertical ridges near the top of the grip in this picture can be a little irritating while shooting. They can easily be removed.


The Grip Force Adapter is an excellent alternative to expensive and permanent grip work. It flattens the backstrap, extends the beaver tail, and enhances grip. It can be easily modified to suit your needs. I would like to see the outer most vertical ridges removed or at least reduced greatly but that is a small gripe that I can fix myself. Overall, this is a very well designed and executed product that solves a few problems for many Glock shooters.

Grip Force Adapters for Glocks

If I spend a day on the range working with my Glocks, it is not uncommon for me to come home with some “race tracks” on my hand. Glocks do not have much in the way of a beaver tail to prevent your hand from riding up too high when using a high, thumbs-forward grip. The slide can cut the web of the shooter’s hand as it reciprocates which results in slide bite or “race tracks”. Many gunsmiths offer beaver tail modifications for the Glock that are achieved by adding material to the frame and shaping it. This permanent modification is effective but may not be practical for some users (police officer’s who can not modify their duty weapon, preventing warranty issues, etc).

Grip Force Adapters seek to solve the issue of slide bite and alter the grip angle of the Glock with one inexpensive and easily installed (and removed) addition to the grip. The Grip Force Adapter is basically a “drop-in” beaver tail for your Glock. It prevents the web of your hand from contacting the slide rails. It also fills in some of the very pronounced curve of the Glock grip’s backstrap which results in a more vertical (1911 like) grip angle. It does increase the trigger reach a bit so it may not be for everyone.

You can check out the Grip Force Adapters for all 4 generations of Glocks at the Grip Force Products website. Stay tuned for a full review in the coming weeks.

Elzetta ZSM

There is no shortage of shotgun light mounts but the vast majority of them are poorly made barrel clamp designs. These mounts often lack the necessary surface area to hold the light securely to the barrel without shifting under recoil and position the light in such a way that a coiled tape switch must be used to activate the light.

The new Elzetta ZSM clamps to both the magazine tube and the barrel. It has plenty of surface area to ensure that it is absolutely stationary under recoil and serves to support the extended magazine tubes that are prevalent on today’s shotguns. It can also be mounted just forward of the fore end which allows the user to active the light with the support hand thumb. The ZSM is versatile enough to fit just about any serious shotgun on the market any and any light with a .70 to 1.05″ outside diameter. That includes most popular lights from Surefire, Streamlight, and Elzetta’s own excellent ZFL-M60.

The ZSM is made from glass-filled polymer which means it is not only extremely tough but also very light weight. There are two models of the ZSM; a standard version and a thumb screw model which allows the ZSM to be detached and attached without the use of tools. The ZSM can also be purchased as a complete kit which includes a 235 lumen Elzetta ZFL-M60 light.

PWS ARC 10/22 Magazine Release Lever

Image courtesy of PWS.

PWS is venturing into the world of 10/22 accessories with their ARC (Advanced Rimfire Components) series. One of the first ARC offerings is an extended magazine release lever that is different from anything I have seen before. Several companies make extended magazine releases for the 10/22 that make it easier to release the magazine with the support hand, but the ARC Magazine Release Lever allows the user to actuate the magazine release with the firing hand while maintaining a firing grip.

The ARC release runs along the front of the trigger guard and has a wide tab that sits within reach of the trigger finger. The shooter simply extends the trigger finger forward and pushes the lever in order to drop the magazine.The entire lever still looks very compact and PWS claims that the magazine will not release accidentally.

The PWS website has more pictures and details.

Inexpensive Addition for the Multitasker TUBE

One of the best things about the previously reviewed Multitasker TUBE is its ability to use standard 1/4″ screw driver bits. This lets the user easily tailor the TUBE to their specific rifle. However, most 1/4″ bits are very short which makes reaching inside the grip to reach the grip screw tricky. There are extended bits available but they can be difficult to find for anything but Phillips or flat head fasteners. This obviously won’t work for grips that use hex fasteners.

The alternative to the extended bits is an extension. An extension will allow you to take advantage of the near endless array of short 1/4″ bits. These extensions are available in several different lengths but a 3″ extension should be sufficient for reaching the grip screw. I purchased the extension from a local hardware store for less than $2 and it tucks away easily in the Multitasker TUBE Expansion Pack carrying case.

I can’t take credit for this idea. I originally saw Ryo mention the extensions in his excellent review of the TUBE on AR15.com.

The extension gives more than enough length to comfortably access the grip screw.

The extension tucks away unobtrusively in the Multitasker TUBE carrying case.
