Hi everyone, I bought a bullboss a few years back and from the get go it was leaking around the firing pin seat. I took it apart cleaned everything and reassembled it and it worked fine, for a while. I took it out two times after then it started again. Went through the process of dis and reassembly and it worked fine for a magazine or two. Sometimes it is a very slow almost unnoticeable leak leading to deminished shot count and other times it is a loud hiss that is quite obvious. Anyone have ideas or a similar problem/solution? TIA. Chuck.
