BM 11, I am looking forward to trying it out as well. My buddy has the same can on a Noveske 14.5 rifle with SF Muzzle break. With a 10 inch upper, it spat flames and kinda sucked, but on a 14.5 upper with the SF brake acting as acting as an additional baffle, it sounds like you're shooting a 22. I swear, it was a completely different experience. I hear they've discontinued it, so you may not get much feedback. But my intention is to basically use it as a big flash suppressor and keep the muzzle blast down a bit. It was going on a Noveske Afghan, but that barrel profile is just too muzzle heavy with a can on it. Instead, the rifle I will put it on is a KAC 14.5 SBR with a dimpled light weight barrel, which should balance out nicely with the little Surefire. I plan to just leave it on there. Ya know what's funny, though, they are discontinuing the micro, but I saw a real short can by KAC at SHOT, that they call the CQB, I think. I don't think the micro can idea is dead just yet.
Oh, and if and when my Noveske MK18 ever comes in, I shall be jonesin for a Mini, like yours.
Thanks for the response, Cheers!
