I bought this with the intention of upgrading but changed my mind and bought a vsr one. I believe it's a Cyma but could be wrong. 

I've taken the cylinder (plus internals), trigger box, hop unit (with maple leaf hop rubber) and transferred them all into this vsr. It fires like a stock tm vsr now.

There is also included a maple leaf hop unit body, a begadi 90 degree cylinder and a spare used tm cylinder and trigger box.
