Doesn't Rob's kit (Apfeltor) now include the springs? The kit I got from him included the springs.I realize this is an older post... I have an Apfeltor kit (well, just bought one today). Is the G-43 spring kit from Sarco a good deal?
The shooters kit now includes the following:
Adjustable Gas Piston (with gas ports, Allen Wrench and instructions)
Recoil Spring Set Total of three springs
New Gas Cylinder
2 ea. Shims
These parts are made from 4140 steel; chromium - molybdenum pre-hardened at 26-32 HRC. Tolerances are generally within .0005 on mating surfaces. The orifices within the piston, clearance between the piston and the id of the cylinder and tension of the return springs have been matched for trouble free operation that has been field tested for ten years.
Did you shoot it at all ? Mine sezied up because of corrosive ammo. Possible someone shot it before and left it ?For the life of me, I cannot unscrew the existing piston from my G43. Is there some trick to it? Do I need to use some liquid wrench or PB Blaster and let it soak?
