Hey ya'll, Been trying to find some parts for a Colt M231 Port-Firing Weapon and have been having a hell of a time, so I thought I would put the word out here as well. I've specifically been looking for the end cap assembly for an M231 Buffer tube. I already have the tube, but I need the end-cap that threads into the end of it with the recoil spring guide still attached. I'm also trying to find the retainer plate that holds in the selector spring. I know there's a few reproductions floating around out there. Let me know if you happen to have one of these parts or know someone who might have them. Thanks!
