TangoDown Shooters Log

Firearms are a lot like your car in that they are a significant investment and they require regular maintenance in order to continue functioning efficiently. Just like your car, it is difficult to ensure that your firearm is up to date on its maintenance intervals unless you are keeping quality records.

The TangoDown Shooters Log is designed to help you organize and record critical information about your firearms, like round count, notes on ammo, and optics settings. The round count is especially important since it determines when your firearm is due for maintenance. I like having a place to track changes to my optics since there have been times when I make a change, only to find that I need to restore the original settings at a later date. It might be easier to track things like this on your computer in a spreadsheet but I still like to have something that I can easily carry to the range with me.

The TangoDown Shooters Logs are available in packs of 5 on the Tango Down website.

AXTS AX762 and AX556 Lower Receivers

I wrote about the A-DAC lower receivers from AXTS Weapons Systems in January. Now AXTS has introduced two new lowers that are absolutely full of new features.

The AX556 and AX762 feature the A-DAC’s right hand bolt catch that is integrated into the magazine release. They also have a number of other innovative features including a flared magazine well, extended bolt stop paddle, and texturing on the magazine well that takes visual cues from the ubiquitous Magpul PMAG.

These lowers will also be available with 45 degree selector markings to support the previously reviewed BAD-ASS-ST.

Magpul MBUS Generation 2 Now Shipping

The original Magpul Back Up Sights (MBUS) were well loved for their combination of functionality and affordability. Now Magpul has released the second generation of the MBUS. Like the originals, the Gen 2 MBUS front and rear sights will be very reasonably priced and be molded in variety of the typical Magpul colors.

The Gen 2 MBUS improves on the original by adding a detent to the front sight so that the front sight post is locked in place. Both the front and rear have been made lower in profile so that they work with a wider variety of optics.

Both the front and rear MBUS can be found on Magpul’s website and should be on dealer shelves shortly.

New Stubby Vertical Grip by Gear Sector

The new Stubby VFG (vertical fore grip) from Gear Sector is now available. It is a no-frills vertical grip that is meant to serve as a reference point, especially when used in conjunction with a hand stop.

The Stubby VFG is machined from 6061 T6 aluminum. The center of the grip has been hollowed out to save weight. The surface of the grip has several rings milled into it that can hold rubber o-rings in place if the users needs more grip. The mounting interface allows the Stubby VFG to be rocked into position rather than being slid on from the muzzle end. This makes installation easier.

Gear Sector mountable accessories are machined in such a way that they blend seamlessly with Tango Down rail covers. This provides a less interrupted, more clean, and snag-free gripping surface. This is the kind of attention to detail that I have come to expect from Gear Sector.

You can read more about the Stubby VFG and all the available colors on the Gear Sector website.

Trijicon HD Night Sights

The new Trijicon HD Nights Sights are now available. Interestingly, they look very much like the Ameriglo I-Dot Pro and Hackathorn sights with some small differences. The Trijicon HD’s rear sight is serrated and has a true “U” notch. They are available in both orange and yellow colors.

You can find more information on the Trijicon website.


Noted handgun course instructor Todd Green has started a new internet forum called Pistol-Forum.com. The new forum is a sister site to his blog, Pistol-Training.com (which is also part of the GunUp blog network).

Shooters of all skill levels are welcome and it is free to join. The forum already boasts some well known and very knowledgeable SMEs (subject matter experts) as members so it is already well on its way to becoming an  invaluable resource for those who are dedicated to honing their skill with a handgun.

You can join the discussion on Pistol-Forum.com.

KRG Bolt Lift

The Bolt Lift fromKinetic Research Group (KRG) is a very clever product for precision shooters. It is a user installed over-sized bolt knob for the ubiquitous Remington 700.

Over-sized bolt knobs are one of the most popular additions to a precision rifle. They provide more grip for the shooter to operate the bolt in cold, wet, muddy, or any other less than desirable condition. You used to have to send the bolt off to a gunsmith who would thread your bolt so that a new over-sized knob could be installed. The KRG Bolt Lift can be easily user installed.

The KRG Bolt Lift consists of two halves that can be screwed together. There are some internal spacers that can be used to fine tune the fit. The Bolt Lift can be installed in such a way that it is easily removable (one screw) or it can be epoxied in place using the epoxy that KRG includes with the Bolt Lift.

The KRG Bolt Lift is available in black only (for now) on the KRG website.

Review: American Rifle Company (ARC) M3 Scope Rings

In this review I will be looking at the M3 Rings from American Rifle Company (ARC). These rings were loaned to me by SexyWeapon.com for the purposes of this review.

The best optic in the world is only as good as the rings that connect it to your rifle. Your scope rings are the interface between your optic and your rifle. They allow the optic and rifle to work together in an efficient manner. Poorly made rings can damage an optic, lose their adjustment, or make a rifle impossible to zero. Quality rings are not an option – they are a necessity.

Specifications and Features

The M3 Rings have many of the hallmarks of quality that we have come to expect from similar products. They are precision machined from 7075 aluminum and feature a black, mil-spec hard anodized finish. They are made in various heights (low to extra high) and sized for 1”, 30mm, 34mm, 35mm, and 40mm diameters. These are the kinds of features that we have come to expect from quality mounting systems but the M3 Rings have several features that really separate them from the crowd.

The most obvious feature is what ARC calls their Tangential Scope Clamp. The part of the ring that clamps on to the scope tube consists of upper and lower parts that are hinged together on one side and connect of the other side via an overlapping surface with 2 screws. The overlapping surface provides a hard stop so that the ring can not be over tightened. The 2 screws are placed on a tangent to the scope tube so that the ring is not distorted in a way that damage the scope tube when the upper portion of the ring is tightened. When the hinged side, overlapping surface, and 2 screws on a tangent are combined you end up with a ring that very evenly disperses the clamping pressure over the entire contact area of the ring to the scope. When you have them in hand and can see how they work, it is very impressive. You can read a more technical explanation of what is happening on the ARC website.

Some scope rings have their weight reduced by milling away parts of the ring where it contacts the scope. This reduces the contact area between the scope and ring which can lead to slipping or scope damage from the clamping forces being concentrated on a smaller area. ARC lightened these rings by milling deep recesses into the surface but not all the way through the material. The result is a lightened ring that doesn’t compromise the contact area between the M3 Ring and the scope. It is a subtle but important touch. The .965″ width of the M3 Rings also helps to provide plenty of contact area between the scope and rings.

One less obvious feature of the M3 Rings is the way that the rings interface with the rail. The crowned interface of the ARC M3 Rings allows for rail variations which are very common among rail manufacturers while still providing very precise contact. Each ring has 2 recoil lugs milled into the bottom of the ring to distribute recoil forces over a large area. ARC has a full explanation along with diagrams and comparisons on their website.

In Use

I was provided a set of extra high, 30mm rings for my review. These rings are a good height for use on an AR-15 flat top upper (they might be a touch short if you have a fixed front sight). I mounted an Aimpoint M2 and a Leupold MK4 1.5-5×20 MR/T for the test. The first thing you will notice is that the hinged upper portion of the rings make mounting the optic extremely easy. Installation is a breeze. You can simply lay the scope in the rings, close the top portion, slide the scope forward and back to set eye relief, and then tighten the two tangential screws.

Since these were loaners rings, I didn’t apply a thread locker as I usually do with all my rings. It was also a good chance to see how the rings would behave without an thread locker. They performed admirably. I wasn’t able to witness mark the screws (like I usually do) but I noticed no loosening of any of the rings under recoil. Once a zero was established, it was held. There were no surprises which is a very good thing when it comes to scope rings. I would still apply some a mild thread locking compound if I was keeping these rings. It is cheap insurance.

I generally do not take notice of whether or not a mount or rings scuffs the rail that they were attached to but since ARC claims that their M3 Ring’s crowned interface will not disfigure the rail, I decided to check. I noticed no marring after the first install and only minimal scuffing after installing and removing the rings a handful of times. This marring probably had more to do with me moving the rings around on the rail than it did with the rings themselves.


These M3 Rings from American Rifle Company really seem to represent an evolutionary step in scope ring development. The hinged, tangential design is amazingly efficient and well executed. It not only protects the scope from damage, but it makes installation simple. These rings represent the culmination of so many good ideas that they just seem to be on a completely different level than other scope mounting products on the market. Everything from the hinged interface and tangential screws to the improved rail interface and construction materials represent quality and innovation.

BattleComp 2.0

BattleComp 2.0 is here. It has the same external dimensions as the A2 flash suppressor which allows the BattleComp 2.0 to integrate with most of the same devices that are meant to work with the A2 flash suppressor. The interior dimensions are nearly identical to that of the BattleComp 1.0 and 1.5 which means that it delivers all the performance that you have come to expect from BattleComp. It comes with a shim kit and Rockset.

You can check it out on the BattleComp website.

Troy BattleRail Alpha

The Troy TRX Extreme BattleRails have been a big success with shooters thanks to their light weight, small outside diameter, and reasonable price. The new BattleRail Alpha builds on the success of the TRX Extreme by refining the mounting system and adding new features.

The BattleRail Alpha is a free float hand guard for the AR-15 family of rifles. Like its predecessor, it is light in weight and has a very slim outside diameter. This smaller outside diameter allows the support hand to wrap around the rail more effectively which increases grip and control.

The BattleRail Alpha features a new mounting system that attaches via the standard AR-15 barrel nut. There were occasional problems with over torqued/stripped screws on the TRX BattleRails, but the system has been improved to preclude that from happening on the BattleRail Alpha. The most obvious addition is the built in spring loaded front sight. This will be a useful addition for some users, but it may interfere with some ways of mounting a weapon light.

This has all the makings of another big hit from Troy Industries.
