Hey guys, I’m new to this forum and just getting back into paintball after about 5 years. Covid got me going through old gear and diving into some builds I never got around to years ago. I’m working on a pump mag and I can’t seem to get it to work correctly. First issue is I have a little bag of parts idk where it goes. It’s a thin rod with wide head and a threaded hole in it. Bag also contains a small set screw and ball bearing. My other issue is I do not have the black rubber washer/bolt buffer and I’m wondering if I can modify a blue one or make one. Just looking for any help, advice, or guidance to another thread. Thanks in advance.
