Ok, so... i had a Prometheus 6.03 for my AK. Come to find out, the barrel was bent. I think it may have happened during shipping, but i havn't really noticed it since i got it, i only used in in a few games. But yeah, well, the barrel cost me close to $70. I want to get another barrel, but from a different company (maybe Evike), and hopefully for a better price. I found one for $29.99. It is a 6.03mm TBB made by Mad Bull. I was wondering if anyoine knows anything about Mad Bull and theuir products before i buy it.
