I have a dedicated 22LR MODEL "1" upper with approx. 35,000 rds. thru it. [ + - ] 10,000 rds. A ROCK RIVER 5.56 X45 Law Enforcement A SMITH & WESSON 5.45X39 UPPER , which I fire com-block,corrosive ammo,{2,1080 rds for $240.00 + $30.00 shipping } from R Guns. Can anybody tell me how to open up there com-bloc tin ,without using a hammer & chisel; when there sometimes supplied can opener does not work? Hornady now sells 5.45x39 steel case topped with a 60 grain V-MAX bullet from NATCHEZ.I am currently building a Rock River 223 Wylde with a drop-in Shilen barrel from Brownells.

I have (2) in 5.56 and (1) in .308. I've been thinking about building another either in 6.5 or .243...

Wow, serious addicts here! I'm just .223 and feel a little weird about it now :).

Had one in 7.62X25 but it turned out to be a POS. I need to find a good one our just build my own.

I have got to get a 458, 450 or 50 one of these days.

Owned 4 AR's and all were 5.56.

yep. Needle-nose vise-grips Snap them on to the tab with the handle pointing up and rotate. I've had to do it at the range with a leatherman once. That sucked ass, and not in a good way.

I have a .223 AI AR that i use for coyotes mostly--
