Hey, I have a problem with my G3 manual (I think.) I'm changing my o-rings on the internals in my gun. However the manual says the front O-ring on the bolt guide is a 15.8/1.9 Oring.
I put the o-ring on the guide and re assembled my G3 however I noticed the 15.8/1.9 Orings that came with my rebuild kit(DP's) are hard and frim

and not soft and squishy like normal orings.
I don't think this is the right o-ring because w/e I gas up the marker there are no leaks but the bolt will not move. There is a tremendous amount of friction between the bolt guide and the bolt.
Any ideas?
