you'll lose alot of fps with the mp5 mag adaptor(v1) . Im sitting at 320 fps with 150psi with a ra tech 6.01 and kfpiston and rouge carrier. Also the TNT bucking sucks ass and needs to be cut flush to function better unless you have the short screw hop adjustment. im getting roughly 175 effective-250 ft range when i use to get 300 ish
