View Full Version : Prometheus Bucking

Hey I have some Prometheus Hop-up bucking but it says that it is the "soft" type. Will that work in a gun that has an M120 spring and is shooting around 400 FPS (with .20's)?

Yes. I believe they are intended for 400fps and below. Anything higher is what the "hard" type is intended. Could be wrong, however.
