[dammitman]

remember those barrels alot of us bought? well i was wondering how the ones caame out that were sent to mark at PF for the fix? was the problem with those a chamber or throat problem? in other words when mark would ream whatever it was he did di that make the barrel into a real SAAMI grendel chamber? i am trying to deciede if i want to even use the thing at all. i dont want to waste time or ammo at all if its just junk. thanks!
