Hello to all, and a hearty thank you for all the great information on this site. Yesterday I bought a used M40, and after going over Cort's Steyr M Disassembly Guide, decided to strip it down completely before firing it. I has a bit too much oil in the assembly, and being somewhat meticulous, I want it right before I fire it. Anyway, I got down to the point where you press the press the limited access lock into the frame (until the spring is completely compressed), and I cannot seem to press it down enough to pull the action carrier out of the frame sub-assembly. Is it possible that there is dirt/grit under the limited access lock, and it won't compress enough? I spent about a 30 minutes trying to pull it out, and I realized that pulling on the action carrier as hard as I was would cause me to lose the spring if it suddenly loosened. At that point I stopped to regroup, and ask for help. Any hints on doing this properly?
