PROCOMP-556-1/2-28 The advanced SureFire ProComp 556 muzzle brake, which fits M4/M16 weapons and variants with 1/2-28 muzzle threads, greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. The ProComp 556 duplicates the design of the SureFire SOCOM SFMB-556-1/2-28 muzzle brake, but unlike the latter it cannot be used to mount SureFire SOCOM suppressors. Precision machined from US mill-certified steel bar stock including high-precision cut threads for optimum thread interface the ProComp 556 muzzle brake has a black Melonite finish that provides maximum protection under harsh environmental conditions. The SureFire ProComp 556 muzzle brake has a blind pilot hole at the 3 and 9 o'clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. Each ProComp 556 muzzle brake is covered by SUREFIRE®s No-Hassle Promise. FITS: M4, M16 and variants with 1/2-28 muzzle threads NOTE: SureFire ProComp muzzle brakes are stand-alone muzzle devices and do not serve as mounts/adapters for any SureFire Fast-Attach sound suppressors. Features Offset porting greatly reduces recoil impulse and muzzle rise so the weapon tracks straight back to keep you on target for faster shot-to-shot recovery Precision machined from US mill-certified steel bar stock High-precision barrel threads for optimum thread interface Pilot holes for tuning of muzzle brake and to pin-and-weld on short-barreled rifles Black Melonite coating provides maximum protection against harsh environmental conditions Installation requires no permanent modifications for M4 / M16 / AR15-type weapons Restrictions ITAR Notice Export of the commodities described herein is strictly prohibited without a valid export license issued by the U.S. Department of State, Office of Defense Trade Controls, prescribed in the International Traffic in Arms Regulation (ITAR), Title 22, Code of Federal Regulations, Parts 120-130.

    Surefire 556 Muzzle Brake

    This is an excellent brake at a reasonable price. I purchased several of them to convert to a featureless rifle. Accuracy improved to boot. I'd buy these again.

    Excellent product.

    I installed this on my recent build and am very pleased. BCM is always a pleasure to order from as well. Fast prompt shipping.

    More on target time

    Excellent product. Greatly reduced recoil compared to the OEM flash suppressor. Lightening fast shipping was icing on the cake.

    What recoil

    Surefires procomp is very nice and well priced. Well worth the upgrade. Greatly reduced felt recoil while shooting off hand and stays on target as it promotes. Great upgrade over a standard A2 flash hider.

    What a difference!

    I must say...I've been a fan of muzzle breaks all my entire gun life! My AR15 originally had an A2 flash hider which was immediately replaced with this muzzle break and what a difference! A MUST HAVE if you want more control-on target acquisition between rapid firing! Made solid, easy to install, and the melonite black finish really compliments my rifle. Not much longer than my original A2 flash hider and performance is unmatched.

    Great comp, especially for the price

    If you don't plan on running a suppressor, these Procomp brakes are perfect. I have them on several guns and love them, especially for the price. There is muzzle blast/flash, which is common with nearly all muzzle brakes, but nothing crazy and definitely makes the gun shoot flatter and softer. Go get one!
