I have a sniper/pump on a 2004 Prostock body. Recently bought an inception Drift kit to try and clean up the action a bit, but the kit did not include a pump arm nut to tension the pump arm against the pump handle. I'm waiting on Inception's customer service to send me the correct nut, but since that part may not arrive before I try to play with the gun this weekend, I want to know what the thread pattern of a standard pump arm is. Perhaps I can find a tiny nut that will do the job for now until the correct part comes in.
