Anybody know which chambers J&T barrels have?
I have two ARs made from J&T kits, one with a standard 20" hbar, another with the fluted lightweight tactical kit. I love them both (but not in a sick way).
Both have shot M193 on a regular basis with no problems, no signs of excessive pressure, etc. More than anything, I'm just curious. There are no marking indicating .223 or 5.56mm on either of my barrels. And it really doesn't say on J&Ts website or in their catalog.
