Precision Armament M41 Review

Muzzle Brakes advocates will sing their praises regarding reduction and taming increase, but Newton’s laws of physics expose the price for them advantages: namely enhanced noise and blast concussion. Personally, I am a massive fan of muzzle brakes since I shoot with lower recoiling rifles, and I like to see the bullet’s influence and trace. Therefore when I first saw these new brakes from precision weapons, I knew I’d to test them out. I wound up ordering two of their most popular brakes – the M11 and the M41 – and now report to the intelligentsia.

Precision Armament? Who? Never heard about them. I clicked onto their website and began checking out their goods – and immediately realized that these men have some talent, and their rates are reasonable to boot. Ok, so here’s the scoop for precision armament. The business is owned by two brothers: Matthew and Stephen Vossler. Matt and Stephen are aerospace and mechanical engineers who have a backdrop making components for the aerospace market.

Two decades ago, Matt and Stephen chose to follow their real passion and branch out into making end strategic firearms accessories. The business is based out from the little town of Wellsville, NY, which is 40-50 miles south-west of the gorgeous Finger Lakes area of New York. Precision Armament has twelve workers, 6 CNC machines, and an extremely bright future. To set themselves apart from the pack, the Vosslers highlight the usage of the most recent state-of-the-art 3D CAD, finite element analysis Multi and applications machining the axes of the exotic allows like reg, Tenealum &, 7068.

The company’s latest product focus is on brakes and hybrid flash hiders, range railings, and bolt knobs. The Precision Armament M41 and the M11 are just two of their most popular products, and I guess their brand new EFAB and AFAB brakes will also be well received as well. M11 Intense Duty&trade, Muzzle Brake. The M11 Intense Duty&trade, muzzle brake takes the traditional side venting, approach to the problem reduce kickback and add a twist: two top ports. It is indeed a work of art and reminds me of the brakes located on WWII era German panzers. That is a break that you’ve to hold in your hands to thoroughly enjoy.

Aside from the quality of the machining, maybe its class is the lines that are aerodynamic that are stunning and its polished satin feel. But there’s more to the M11 than excellent looks. The brake is made of heat treated stress 400 Series Stainless Steel. This substance retains good dimensional stability throughout the cutting procedure and a lot more corrosion and erosion resistance compared to conventional chrome moly steel.

The Brake is also finished in state-of-the artwork Diamond Like Carbon At a low luster Matt Black. The brake’s massive blast deflectors create three separate blast chambers. The first chamber Is the biggest, and all the two chambers decrease in size. The last two blast chambers contain big vents at the top of the brake so that gas is directed to keep the muzzle down. TTAG writer Jeremy S. Recorded this awesome money shot of the M11 in mid-blast: The explosion shields are just angled ever so slightly to the back. In this aspect, Precision Armament is creating a deliberate effort to equilibrium reduction of recoil against negative ramifications associated with led noise and concussive effect.

Consequently, this brake is loudly, but not as strong as the other brakes I’ve used. The M11 is a nonsymmetrical brake, and, because of this, has to be properly timed, or indexed. , Traditionally, muzzle brake designers have taken two approaches to this problem. Companies like Grizzly Gunworks utilize an Allen screw clamp system to index their threaded wheels. While this method has the advantage of being easy to remove for cleaning, it does increase bulk, weight, and theoretically, could get stripped out. Precision Armament desired to keep the svelte aesthetics for the M11, so it opted to utilize a set of custom sizing washers.

Notably, Precision Armament doesn’t recommend the usage of crush washers, due to the inherent possibility of misalignment. In place of crush washers, Precision Armament designed the proprietary Accu Washer&trade, Muzzle Alignment System. The set is made up of series of 18 individually marked washers, all a different width. Employing these washers, the timing is adjustable from 0-360 degrees in 20 deg increments. The washers are precision machined from high strength 400 series stainless steel to some guaranteed thickness uniformity of ±, 0.0001. The precise tolerances of those washers ensure the most precise bore alignment possible. Since just one Accu Washer is required for every gun, the system avoids cumulative effects, a problem that is usually associated with peel washers along with other shim systems.

It took me about one hour of sorting and trial and error fitting to find the time right on my model Savage Model 10 TR, but now that I have the correct washer chosen, I will remove and reinstall the brake at less than a moment. The Accu Washers work nicely, but some people aren’t going to like that the washer stays visible once installed. The M11 is threaded for 5/8 – 24 threads and can be made to fit one of the four bullet diameters: 6.5 mm, 6.8 mm, 7.62 mm, and 8.6 mm. This is my overview of the advantages and drawbacks of the M11: Benefits! Dust Suppression for prone shooting. Doesn’t tend to loosen up. Fantastic reduction. Relatively easy to clean because of large baffles.

The very first time consuming it’s time consuming due to the timing, issue. Louder than M41. M41 Severe Duty&trade, Muzzle Brake. Spiral axisymmetric, muzzle brakes have been around for a little while, but with the M41, Precision armament adopts the concept to another level by expanding the traditional small diameter round ports into three collections of five rounded helical ports. Combined, these ports create three different blast chambers, exactly enjoy the M11. Unlike the M11, but the M41 designed to cancel linear and torsional recoil forces. For a typical right-hand Twist barrel, the brake needs to apply torque in the same direction as it screws off.

That, naturally, implies that the brake will want to loosen itself. Companies like HK design their pistols with left-hand threads, which fixes that problem, but creates compatibility problems. Precision Armament believes that the latter is a big evil because adequate tightening with a torque wrench to Will be appropriate to counteract the slimming effect. Nevertheless, to fight the loosening, issue, you need to set up the brake to the torque specification set out in the instructions. Precision Armament urges 20 ft lbs, that is a considerable amount. Using an example, putting all of your might into it bare handed, you might get 2-3 feet lbs.

PA does manufacture a wrench for the job. You must not put the barrel in a barrel vise to get it to spec. However, it will help. We did not get it right on our very first attempt and paid the cost. As the brake loosened, we noticed a sudden and different downward POI change. We were quick to diagnose the problem. I glad we did not dismiss it off the barrel! Courtesy Joe Grine. One nice touch on the M41 is the engraved Precision Armament, logo on the front of the brake. It provides your target something to read while you dial on your dope.

Ha! The photograph above shows the M41’s helical blast chambers, as well the curved holes for the custom wrench used to loosen and tighten the brake. The above photo shows another close up of the company end of an M41. M41 is threaded for 5/8 – 24 yarns and it is made to accommodate one of 3 bullet diameters: 6.5 mm, 7.62 mm, and 8.6 mm. Therefore, to outline the M41: Benefits! Symmetrical design: No desire to the indicator, or time, the brake to the barrel. The intense reduction in felt recoil. Fewer concussions than M11 and comparable side venting designs.

Theoretically, it should be best for precision. Look great! Disadvantages: Brake would like to loosen itself therefore significant to put in quite firmly, use Loctite and torque wrench. Gas vents in most directions: no dust suppression characteristics. Better for a bench, shooting thanks to dust issue. Uses proprietary $20 instrument to set up.

The obvious question is: that brake do we like better? Even though these are very subjective assessments, it appears the edge goes to M41, because it’s slightly better recoil attenuation with less concussive effect. None of the two brakes had any negative impact on accuracy, and the recoil that is mild might in fact indirectly help in getting wider groups. With that said, if you take prone on sand or dirt, the M11 offers much superior dust suppression, because when compared to the M41. Specifications: Materials: HTRS-400 Series Stainless Steel. End: Diamond Like Carbon Matt Black, or in the white,).

Cost: $120. Tests: Performance: As I’ve mentioned before, muzzle brakes are not rocketed science, they represent straightforward Newtonian physics in operation. Nevertheless, Precision Armament is pushing the envelope toward supply state-of-the-art computer designed brakes that optimize strength to weight ratios. Durability:?. Hard to assess in the short term. However, PA’s use of top quality materials, computer-assisted designs, and precision tolerances give me confidence that these wheels will last forever. Value:

Overall, the prices of PA are very reasonable, with the possible exception of the M41 wrench, which, at $20, seems overpriced. You will find brakes, but it is doubtful that they’ll exhibit the same degree of quality and workmanship. Overall: A strong buy recommendation.
