Suppressors What happened to my AAC cyclone muzzle?

[caspian]

Shot about 1K rounds through my Cyclone (.30 cal) on my SAW M249S. It got hot as hell, burned off the finish. No big deal. But the end is flared out. No clear signs of baffle strikes since it is pretty uniform and no clear abrasions. I was shooting Wolf 55 gr.

Anyone else have this happen? IIRC, the cyclone is rated .30 cal full auto.

Thanks in advance,
Chris

My bets are either, 1, it was a little loose and you got some strikes that hit the endcap only, or 2, the bullets weren't fully stable coming out and thus hit the endcap

Now that i think about it, it was probably closer to 800 rounds........4 - 200 round drums with breaks.

actually, it was loose (maybe 2 turns max) when i went to check it after a session, so may be it. but they don't look like solid stikes, which is why i asked.

Mine had a single 308 end cap strike. It was on a new barrel so we thought it might have been thread concentricity. We traced it back to the "face" of the can having a small nick in it. It was put in the lathe and cleaned up and had been fine since. Something else to watch out for with direct thread and just another reason I prefer something like TBAC's brake mounts. I think the can could probably come loose a turn or two and still not have a strike since the tolerances are pretty tight and all controlled by the MFG. No guessing how good of a job your gunsmith did on the muzzle thread to can thread fit.
