Razorback trigger frame screw
This is how I created a back screw for my Razorback.
History-I loaned my Razorback out to my son’s friend for some woodsball. He was new to the game and needed something simple to use. He later brought it to me saying it was no longer working. The back screw was missing.
Lesson #1; Teflon tape all exterior screws when loaning a paintball gun.
I used a Phantom back screw. It was too long but had the proper threads (10-32 NF or Fine thread). I initially got the gun back in working order by using the Phantom screw and a couple of washers.
Later I bought a die set (about $6 total for the die and handle) and ran the threads all the way to the base of the screw (remove the rubber washer, use oil, wear goggles, etc.

).
I then installed two nuts, locking them into place (turn them against each other) and leaving the thickness of the two washers I used above the nuts (about an eighth to a quarter of an inch, use common sense. Lacking that; measure it twice, cut once

). I took my Dremel and cut that amount off. I removed one nut and use the Dremel to bevel the edge of the screw like it was originally then removed the second nut.
I test fitted it and it worked, the gun is now back in working order.
I had tried buying a parts gun but realized if I did that I would have just worked until the parts gun was shooting too. This was lots cheaper.
