Great for the price

Machining is excellent and the Melonite finish looks good. It’s an effective brake, and has been a great addition to my firearm. The price is very good compared to the same one with the QD suppressor mount.

Exceptional Equipment, Bargain Price

Fantastic brake, on par with the performance from the MB556K but a lot cheaper if you do not need the suppressor mount capability. A great product for the price!

Never received my order

I recently ordered three PROCOMP 556s and never received them. I informed customer service of the situation in which I never received a reply back from them. I would like to see this situation resolved because I have never had a problem with Surefire in the past.

procomp 556

Nice addition to my Sig M400. Easy to install. Over all appearance and finish was nice and clean. Really helps with muzzle rise and follow up shots. This thing is LOUD! Got it at 50% off during SureFire's sale. Well worth the money.

Great Product

I'm really enjoying the muzzle device! Performs as advertised by reducing muzzle rise and recoil. Only gave 3 stars for service because it took a long time and 3 emails to get a response regarding my backorder status...this may have been due to increased holiday sales volume, but for the price I got this for on black Friday I can't wine too much.

I will purchase from surefire again!

procomp 556

fit great on my AR worked great but just some minor issues I had with it 1 : the procomp I received was not completely finished, it still need one port hole location to be fully drill throught on the left side of it and was making zeroing impossible, 2: since it was not zeroing it was causing the bullet to go low and not where I was aiming at

Description

PROCOMP-556-1/2-28
PROCOMP-556-1/2-28 84871323512

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.
