    Well this was what I got back from a guy at T1G about the SF can.

    The SF can's are nice but I have had 2 of them break on me using M855. The 1st baffle was knocked out and then the rest got knocked out after the 2nd round hit the knocked out baffle and send the round tumbling through the rest. I called SF and they said it's never happend to them.... (sure).... a week later one of my instructors had the same thing happen.

    I have one 212 can with well over 10K through it. With that said, I do not do mag dumps through my guns as, well it serves no purpose.

    Decibels don't mean much, except on paper.

    Right. DB rating with a gun shooting a bullet that breaks the sound barrier is pointless.

    All that really matters (to me) is POI of shift.

    Both of my AAC cans have a POI shift of about 3 inches at 100yds. Now that doesn't sound like a whole lot, but if I am shooting at someone at 200yds, now I am 6 inches off. This becomes a problem.

    I have to wonder if they weren't shooting XM855. This ammo just flat out sucks and most likely caused a baffle strike.

    Putting your can on a crappy barrel or shooting crap ammo through it means that you deserve what you get.

    I'm gonna ask a dumb question now. If I leave the can on the rifle all the time, POI shift doesn't mean anything, correct? I would sight it in with the can on, then it doesn't matter what it is without the can if I'm not going to shoot it without it. I've thought about the Gemtech Trek, but now I'm considering the G5 and the AAC M42K as well.

    Correct.

    SF uses M855 for their testing since it is the current MIL round.

    As an aside, while I agree that arguing over 1 or 2 dB with a supersonic round is not productive, I do think that dB ratings factor heavily into the picture- sure, the bullet flight is loud, but the difference at the muzzle between 135 and 145 is huge in terms of the shooter's experience. if sound doesn't matter with a supersonic round, why even have a can at all?

    Another note, the average shooter will never ever burn out the KAC, AAC, or SF can.

    there are lots of criteria for choosing a 5.56 can (I think I wrote an article on this, but if not maybe I should...)
    First, eliminate anyone working out of their garage. I don't care HOW cool it looks, he's working out of his garage. Stick with the big boys like AAC, Gemtech, Ops Inc., KAC, Surefire, etc. You know, people that do this for a living. At that point DB ratings become almost meaningless.

    After that, you have:
    1. weight
    2. length
    3. length added to gun/barrel
    4. mounting system
    5. mount itself
    6. cost
    7. POI shift
    8. multi-platform?
    9. multi-caliber?
    10. etc.

    Baffle strikes are almost always related to issues with the bullet, barrel or mount installation. I had a strike caused by the latter and SF fixed it free of charge.

    Maybe I got lucky. My KAC can (soon to be plural there) only has a 1.3'' shift vertically. (Up.)

    Does anybody have similar?

    I AAC can I had had a 4 shift even. (two inches right and two inches up)

    I do admit that the AAC can handled a little better on the LWRCi than the KAC did on the KAC.

    I'm sure it was because of the light weight muzzle device on the piston gun, vs the kind of heavier device on the lighter DI gun though. YMMV and all.
    We miss you, AC.
