Enables attachment of FA556K or FA556-212 suppressors to Colt Commando, M4, M16, HK 416 with 14.5" or longer barrel, and to other 5.56mm (.223 cal.) semi-auto, bolt-action, or assault rifles with Mil-Spec 1/2-28 muzzle threads and (due to slight overlap) first .170" of barrel behind thread shoulder clear of obstructions and no more than .800" in diameter. This adapter functions alone as a high-performance muzzle brake when the suppressor is removed. Patented design greatly diffuses side blast, counteracts up/right muzzle movement to keep muzzle on target, eliminates felt concussion on shooter. Heat-treated stainless steel construction.
This model offers a extended shoulder to blind pin and weld for permanent attachement to barrels.

Good to go April 26, 2012
Reviewer: Anonymous Person  
Ordered Monday, received Wednesday :)

Comes with shims, instructions, alignment wheel, warranty card, etc.

Identical to MB556K except for an 1/8th (approx) lip off the back of the device, with a pre-drilled hole for pinning.

The diameter of the lip is almost the same profile as a Noveske N4 profile chrome-lined barrel.

Very pleased with BCM on their timeliness in shipping, and SureFire with their product.

Although, getting an actual product photo may be helpful to future customers.
