What is the PRECISION ARMAMENT - AR .308 M4-72 SEVERE-DUTY BRAKE 30 CALIBER?

Compensator features a large initial expansion chamber which dissipates combustion gases at a lower pressure, then directs the gases to the side and rear through precisely canted vents. Innovative reverse venting design reduces recoil and blowback while eliminating muzzle rise. Closed bottom in compensator greatly diminishes dust signature. Machined from high strength stainless steel for corrosion resistance, compensator will not erode due to the extreme heat of automatic fire. Requires use of Accu-Washers sold seperately for proper installation.

SPECS: HTSR 416 stainless steel bar stock, matte black or in-the-white stainless steel finish. 1/2-28 TPI thread. 2.25" (5.2cm) OAL. 0.875" (2.2cm) dia. 2.6 oz (73.7g) wt. Fits .223 Cal (5.56mm) caliber. A04020 and A04021 fit .308 caliber and have 5/8x24 threads.

Purchased a second one .

Installed on a Rem 700 16 barrel, reduced recoil as advertised.

Looks Good & Performs

Installed on my bolt action Savage .308 using a shim kit. I have shot with and without the muzzle break to compare. Mitigated recoil significantly which it made it much quicker to see your shot or perform follow-up shots. There's is that study on TruthAboutGuns that showed a 64.43% in recoil reduction for their test firearm. Not sure how accurate that is, but it sounded good to me. Also, I personally like the aesthetics of this muzzle break.

Best muzzle brake for the money

I have several pa muzzle brakes 7 to be exact. This will make your ar shoot like a .22mag. Guaranteed!!!

SUPER RECOIL REDUCER!!!

I have installed several in both .223 & .308. Recoil reduction is second to none, very nuetral brake, in 223 muzzle movement almost eliminated! IMPORTANT NOTE, with extended forearm make sure there is at least a FEW INCHES BETWEEN BACK OF BRAKE AND END OF FOREARM or gas will be trapped and funneled strait back.

Perfect on the Remington 700 5R

After much searching and research I installed the stainless M4-72 on my Remington 700 5R Gen 2 .308. Very easy install when using the shim kit from Precision Armament. Recoil and muzzle jump were GREATLY reduced after install. Its loud, as always, wear your ears. Excellent product, highly recommend this product for anyone wanting a great all around break that keeps its curb appeal.
