A member @jtallen83 had a gas problem with his turns out the gas port in the barrel was to small. Easy fix, but their reps blamed it on everything but the barrel, other members helped him trace it to the port and what to drill it to. The rep even joined the forum and still wouldn't except it was the barrel. Jt asked the rep what size the gas port should be and he acted as if it was triple classified info. I told a friend of mine in the industry that and he lol'd a lot. Anyways the members here got JT going, but X-cal showed that they're a sub par company......
