Cavalry Manufacturing MK17S SCAR-H Billet Lower

Cav Arms FN SCAR 17 PMAG Lower

I have been trying to keep you up to date on the new MK17S SCAR-H Billet Lower from Cavalry Manufacturing as it moved through the development phase. Well, I am happy to report that it is now available. This billet lower receiver will accept all SR-25 pattern mags including PMAGs so that your SCAR-H can have magazine commonality with other rifles in your inventory or you can just take advantage of the better pricing, availability, and durability of the SR-25 pattern mags.

You can order direct from Cavalry Manufacturing and since the lower receiver is not the serialized part of the SCAR-H, it can be ordered without an FFL.

TacStrike Update

TacStrike, makers of steel targets for high volume training, is changing they way they do business in order to better serve shooters. They have been busy lowering prices and reducing lead times in preparation for these changes. Here is the rest of the story from Rob at TacStrike…

TacStrike 14 Scale

“TacStrike would like to bring everyone into the loop on current events here at TacStrike. As you may have noticed we have been putting a lot of new information onto our wall and most of it has to do with sales and lower prices. As of last week Yvonne and I decided that continued pursuit of dealers (gun shops, sporting goods stores, etc) was detrimental to the future of the business.

Having dealerships forces a double pricing structure that makes everyone a little money but because steel is inherently hard to ship setting it so that dealers can make money on their end is a hard thing to do and stay competitive.

So effective immediately our dealers have been informed and they are clearing out inventory and/or I’m buying it back from them so that they are not stuck with it and TacStrike has slashed prices on everything we make.

Targets, Carriers, Steel, Gongs, Our Cardboard BSYF Targets and everything we have coming out have been deeply discounted to a new low price. No change in quality but a huge savings for the end users.

We are suffering a bit of a lead time right now but we will be fixed next week as I have production runs of everything we make in assembly and paint right now.

Our focus is still on training and you will continue to see great product lines that are training oriented coming to TacStrike and our target line growing as we take things from the drawing board to the range for T&E.

Yvonne and I are the only ones answering emails and calls and we touch every package as it heads to you. We are trying to be epitomi of a small business family and we are doing it while working our regular full time jobs with the hope that one day TacStrike will provide for our family.

We appreciate every one of you more than you can imagine.”

Thank you.

Review: BattleComp 1.0

I have been able to test and review a ton of muzzle devices but one that I have never reviewed (though I have plenty of time on them) is the BattleComp. A few of you have even emailed me to ask if I didn’t like them. That isn’t the case at all. I have just never reviewed them.  I recently purchased another BattleComp 1.0. So, while it was still looking new for pictures, I thought this would be the perfect opportunity to finally put together a review.

BattleComp 1.0

Overview

The BattleComp 1.0 is made from 17-4PH stainless steel. It is available with a bead blast or black oxide finish. It features a single expansion chamber and several small ports around the circumference of the device except for the bottom portion which is closed.

Most of my experience is with the 5.56 versions, though I have tried a 7.62 version. This review will deal exclusively with the 5.56 BattleComp 1.0.

Background

The BattleComp is largely responsible for the current arms race that you see taking place in the industry between muzzle device manufacturers. It was one of the first devices on the market to be viewed as a compensator that is suitable for “tactical” use and it was somewhat revolutionary in how it balanced flash suppression, muzzle and recoil control, and reduced the concussive blast that is typical of most compensators and muzzle brakes. A lot of new devices have come on the market since the introduction of the BattleComp, but it is still the standard by which others are judged as evidenced by how frequently it is used as a baseline of comparison in muzzle device reviews.

Observations from Use

There are 3 main tasks that we generally ask muzzle devices to do: suppress flash, reduce recoil, and reduce muzzle rise. Most devices will either suppress flash well or reduce recoil and muzzle rise well. Combination devices (devices with the characteristics of a flash suppressor and compensator or muzzle brake), like the BattleComp, attempt to complete all three tasks. The extent to which the device does these things and other characteristics, like over-pressure and noise to the shooter and those around him, largely determine how the muzzle device should be used. Most muzzle brakes will not be suitable for the indoor spaces you will encounter in home defense and most flash suppressors will cost you valuable seconds in competition. It is up to you to determine which task or tasks are most important to you and your mission and then choose a muzzle device accordingly.

BattleComp 1.0 Front

BattleComp takes on all three tasks fairly successfully. It suppresses flash, reduces recoil and controls muzzle rise and because it manages to do these things without the dramatic over-pressure and concussive blast that has traditionally plagued compensators, it is suitable for uses that typical compensators are not suitable for, like self-defense. Make no mistake, the BattleComp is still louder than a flash suppressor. Standing in close proximity to it won’t be pleasant, but it is tolerable, especially when compared to a comp or brake with large open side ports.

I find that BattleComp does an admirable job of suppressing flash. It isn’t going to keep up with a dedicated flash suppressor but it does a good job compared to most combination devices. On a 16” barrel, it suppresses flash nearly as well as an A2 flash suppressor. This may or may not be black magic because there are other devices out there that I have tried that look similar to a BattleComp (a cylinder with lots of tiny holes) but few of them suppress flash as well as the BattleComp.

BattleComp does a great job of reducing recoil. It is true that the 5.56 does not have a lot of recoil but reducing what little recoil it does have means faster follow up shots. Recoil control is an important part of muzzle control because the rearward motion of the carbine is translated into upward movement of the muzzle as the stock hinges against your shoulder. This is why lowering the stock in your shoulder can be an effective way to reduce muzzle rise – it reduces the hinge effect.

BattleComp 1.0 Mark

The way the BattleComp controls the muzzle is one of the best things about it and also its biggest weakness. I find the BattleComp to be very laterally stable which I find very noticeable and very impressive. Some muzzle devices let the muzzle bounce side to side very slightly. They seem to almost dance around in a circular motion. This isn’t the case in my experience with the BattleComp. It moves only one direction and that is down. Unfortunately, it moves down more than I would prefer. The bad news is that a muzzle device that pushes the muzzle down too aggressively isn’t all that different than a muzzle device that allows the muzzle to rise – you still need to move the muzzle back on target. The good news is that the movement is very predictable and you can be extremely fast with BattleComps.

Wrap Up

The BattleComp does push the muzzle down more than I prefer and that is a fairly serious issue for me. In spite of that, I am not sure that any device has surpassed its all-around versatility and functionality which is why I still use them. The BattleComp suppresses flash, reduces recoil, and keeps the muzzle very stable. It manages to do all of these things without kicking you in the teeth every time you pull the trigger. It isn’t the perfect muzzle device (hint: the perfect muzzle device doesn’t exist, at least not without a tax stamp), but it is one of the best.

GG&G 45 Degree Transition Sights

45-Degree-Transition-Sight

While the offset iron sight concept seems to be gaining traction, there still aren’t more than a handful of manufacturers that are actually producing them. I just learned of a fairly recent addition to that short list from Harris Tactical. The GG&G 45 Degree Transition Sights look like they split the middle between some of the offset iron sight sets that are currently available. They offer more precision than something like the XS Sights XTI but lack all the adjustment at the rear sight like the Dueck Defense RTS (which some users may not need).

GWACS Armory CAV-15 MKII Improvements

Several months ago I wrote a review of the GWACS Armory CAV-15 MKII AR-15 lower receiver. I was actually surprised by how much I liked it. They just work and don’t seem to have the durability issues of other polymer lowers on the market.

In the review, I mentioned a few fit and finish issues that I noticed: the finish on the take down pins was so bad that they looked used before I even installed them and there was plastic flashing left in the magazine well. GWACS Armory immediately acknowledged the issues and said they would work to correct them… and they did.

GWACS Armory Improved Pins

I have been able to check out a handful of their recent CAV-15 MKII lowers, including a new one that they sent me to show off the improvements. The fit and finish on the take down pins has been MUCH better. The new finish appears to be a deep, black oxide that has held up very well for me. Even after being installed and removed several times, the pins show little wear and look much better than the previous ones even when they were new.

They also addressed some of the plastic flashing issues. GWACS Armory is obviously taking a bit more time cleaning up the lowers by hand after the two halves are fused. The bottom of the grip and the magazine well are much cleaner on this newest example.

GWACS Armory Buffer

All CAV-15 MKII also now come with GWACS Armory’s new distinctive buffer. It is a standard weight buffer (H buffers will be available soon as an option) that is hard anodized bright red and branded with a GWACS Armory logo. This isn’t really a functional improvement (though this buffer is of a higher quality than the one that came in my previous lower) but it does add the type of detail that rounds out a lower and lets you know that the company behind it gives a rip.

It is great to see a company responding to customer feedback the way the GWACS Armory has with these new improvements to the CAV-15 MKII. Check out GWACSArmory.com. Use discount code “triggerjerk” to save 5% off your purchase.
