Griffin Armament M4SD FlashComp 5.56mm 1/2x28 Threads

by Joe
This device has managed to find its way onto most of my rifle builds. Based largely on an excellent review from
Militarymorons.com, I decided to try the M4SD-II and haven’t looked back since. All the great recoil reducing characteristics of many of the other comps out there but with reduced blast signature and reduction in flash instead of your typical flash ENHANCEMENT situations. This is the droid you are looking for. View More SKD Staff Picks

Ten years of muzzle device research, design, testing, and manufacturing resulted in our latest revision FlashComp. With winning features of our Hammer Comp integrated, the new flash comp adds an additional sacrificial baffle, offers better flash signature, and is reduced in weight!

The Griffin Armament M4SD muzzle devices interface with our M4SDK, M4SD2, M4SD, and 30SD suppressors.

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 (for mounting to suppressor).

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

5 of 5 Awesome September 28, 2016
Reviewer: Nick from Indiana  
I bought this over a year ago from griffin directly and attached it to my SBR. This thing is amazing at keeping muzzle rise down. I was able to keep my rifle on target with rapid shots with little effort.  When I'm at the range people beside me don't like it to much due to concussion haha. Either way great product and i'm looking into their .30 cal comp for my 308.

5 of 5 M4SD-II Flash Comp April 20, 2016
Reviewer: Fred F from West Palm Beach, FL United States  
This is a great item and really makes a difference with my AR-15. We fired this without the light, and it really reduces the flash.

5 of 5 A successful hybrid, great retailer! February 14, 2016
Reviewer: Citizen from Kuna, ID United States  
Muzzle climb is more manageable vs A2 and allows focus on following shots. Not obnoxiously loud, good when prone (low kickup). Can't really comment on flash as dusk is the most I've done with it.

Well made and a solid choice. Will be adding the GA suppressor.

SKD was fast, solid, and rocks.
