I am having problems with the bolt in my DPMS LR-308 short stroking on occasion and catching the next round in the middle of the case. Details and pictures here..
I noticed that there was some carbon and soot on the barrel in front of my gas block (PRI low profile) so I took the hand guard and the gas block off to have a looksee. The carbon was about 1/8th inch from the forward edge of the gas block, and underneath there was a thin coating of carbon/soot everywhere the gas block covered. I cleaned off the surfaces and put it back on, taking care to torque the two set screws down to 30 inch lbs this time with a bit of loc-tight.
My question is: will that little bit of a leak cause the bolt to short stroke (about one in twenty rounds)?
....been wondering the same thing.
