    Owned this for about 2 months/600-700 rounds. Very pleased. Noticeable difference over my Surefire fa556-212. A hair longer, a hair heavier, but definitely quieter. Surefire mount is awesome but suppressor gets stuck on after 100 rounds or so. Specwar never freezes up. Comes right off. Nice, small bore size. No POI shift that I can tell. Best friend runs m4 2000. If his didn’t ring like a doorbell every shot, they would be about the same. Specwar mount is superior to m4-2000. Its about the best value in fast attach 5.56 suppressors. As quiet as they come plus full Stellite core = ultimate durability.

    Mine is still in jail, but I was able to put ~250-300 rounds through it with my SOT. VERY quiet (for a .223). Sounded like a 22 LR rifle. Other people at the range didn’t believe I was shooting .223! The Trifecta flash hider has no tuning fork effect at all. Four stars due to one minor issue. The exit hole on the end cap is a bit (1/32″) off center. SWR said this was cosmetic only as the bore of the silencer is wire cut to be perfectly concentric with the smallest possible hole in the end cap. They explained they could have cleaned it up to be centered perfectly, but it would sacrifice suppression as they would have to make it larger. Since I got the can to use and not for looks, I’m fine with that.
