Weird... there's at least 4 variants of barrels then. Lol... The hardened rods in them SUCK to cut for REAL. hahaha
BTW I have an extra AS flash hider if you need.
oh man, what are the others? The real one looks like it has a messy plug in the end.
Also, you're so right. I was slicing through the zinc like "oh this isn't so bad" and then this high pitched noise came and my progress slooowwed. I swore a lot.
Also, is it the non-bead blasted one? My dad is making one of these too, he'll want it, we could just buff my old one down and end up with two fresh ones....
