I had one of the pit metal bodied cymas a few years ago and it was am amazing little gun, till I went arse over tit and snapped it in two. I them replaced it with an E&L which was absolute crap. It kept jamming up every few shots. In the end I put the cyma internals in the E&L body.
I'd say get the cyma, especially if its the one with steel externals
Fixed. I didn't bother cleaning mine properly to get that knackered battlefield trophy look and it didn't take long
