Well I've been using a white lithium grease but I think I need something more of a petroleum jelly sort of consistency. Any suggestions would be great.
I have the X-ring on my piston.
The one thing I've noticed is there is not a very close fit between the piston and the cylinder wall. You'd think the blow-back would function much better with a decent seal.
Also the top seal (part # M15) on my mags are showing wear from the bolt-carrier sliding across them. Could it be my carrier has some extra casting flash or is out of tolerance?
Cheers,
Grant
