Prometheus has a FTK or i have to buy the parts separately?

Thanks skruface for posting the links. The question that I have to ask you is what is your gun shooting now? their is nothing wrong with 350. If you are concerned about "X" part breaking then you should never upgrade. I have guns shooting 380 with almost all stock TM parts (only cylinder change) and a M110 spring.

having been an excessive upgrader and tinkerer i've realized that in a large number of cases upgrades are the root of malfunctions in a gun.
