Accuratechad Posted January 25 Report Share Posted January 25 Without a military gage, can someone advise what an acceptable reading range for the diameter of a gas piston? Quote Link to comment Share on other sites More sharing options...
GUNBUGS Posted January 29 Report Share Posted January 29 .5253" minimum to .5260" maximum. .5250" is a no-go. Also check to make sure it is round and not egg shaped. Also the cylinder must be within spec and not out of round. Quote Link to comment Share on other sites More sharing options...
