The Griffin Armament M4SD muzzle devices interface with our M4SD series of silencers.

The M4SD Flash Comp optimally combines the functions of three traditionally separate classes of devices- Muzzle Brakes, Tactical Compensators, and Flash Suppressors. The M4SD II Flash Comp achieved a perfect 5 out of 5 in National Tactical Officers Association testing to achieve the rare, coveted, NTOA Gold seal of approval granted to devices which achieve perfect evaluations.

Compatible with the M4SD series SD-QD suppressor interface the Flash Comp provides a sacrificial baffle to increase the service life of your silencer. It is also pre drilled, and 2.25” length for 14.5” to 16” permanently attached, Non-SBR, M4 carbine builds. For optimal flash reduction we recommend 14.5″ or longer barreled host weapons. Extreme durability, low concussion flash and recoil reduction are the wave of the future- the Flash Comp provides an elegant solution to a complex problem. Includes shim set and over-travel stop washer.

Over-travel stop tab should be positioned at the bottom of the muzzle device (6 Oclock).

Flat out rocks August 18, 2016
Reviewer: Brad West from Dallas, TX United States  
Those three words pretty much describe it.  You'll shoot super flat, which is fantastic.  I definitely felt like I had much more muzzle control and consistently shot flat.  The caveat to that is it's louder than your A2 birdcage, which is to be expected with any sort of comp or brake.  Fit and finish is immaculate which is one of the things I love about Griffin.  Next up is the M4SD silencer to go along with my flash comp.

Excellent product! July 24, 2016
Reviewer: Mason W. from Minnesota, United States  
After shooting several different muzzle devices and brakes from numerous companies throughout the industry, (surefire, lantac, cmmg, KAC, and the old faithful A2) this is by far the best blend of not only reducing muzzle climb, but mitigating flash as well. Top notch fit and finish, and compatible with several different cans and brake shields that Griffin offers. For the price you will be hard pressed to find better value from any other manufacturers in the market.

It Sure Is A Flash Comp January 13, 2016
Reviewer: Timothy Moua from Roebuck, SC United States  
I have the M4SD-II Flash Comp on a mid length 16" build and it is a tack driver! I was pretty surprised with the muzzle rise reduction and the muzzle flash reduction. It does a great job of both. However, the concussion is pretty harsh. You DO NOT want to shoot with no ear protection. Especially indoors. If you're looking for a muzzle rise/muzzle flash device, look no further. This one does the job.

Note: When installing, make sure the Griffin Armament emblem is at the 6 o'clock position.
