Sorry it took so long but I just had a chance today to put a second range day on this new mount. About a month ago I posted that I had trouble with my Phantom & SOCOM mount from my M4-2000 2006 model suffering from serious carbon fouling to the point it took two people to wrestle the can off the rifle. Kevin from AAC offered to exchange one of my mounts for the new Blackout mount. I received the new mount very quickly (thank you AAC) and installed it on one of my AR's.
The new mount has a very tough and attractive finish (scarmor?) along with the new flash hider style that looks like an old M16A1 flash hider with 3 prongs. But the best thing about the new mount is that the can is full tight with the spring in the last valley. My other 3 mounts all suffered from the loosening up a half click thing. There were never any concerns for a baffle strike or accuracy issues (i left it a half click loose all the time). The new mount locks up tighter than a bull's ass
I have about 300 rounds through the new mount with zero carbon locking issues. The can screws on and off easily every time. I am using a 16" AR RR with Fed AE 55 grain, some full auto mixed with semi.
Even though there were never any concentricity issues with the old mounts, the fact that this new one locks up perfectly makes my teeth sweat, it makes a near perfect can into a perfect can.
I do have one question about the new mount, it rings like a bell when fired without the can, and it rings if I flick it with my fingernail. The 3 prong setup seems to act like a tuning fork. It is not too disconcerting but it is peculiar.
I am definetly pleased and impressed by the new mount, thanks AAC for standing behind your product and sending me this awesome mount.
