A coworker presented me with a dilemma today. He was boresighting his AR and managed to let the bolt slam home on the chambered boresight device. He called me to ask what to do and I told him to collapse the buttstock and bang the butt on the floor while pulling hard on the charging handle. He said it won't work. I told him the I had always been able to remove stuck rounds that way with no issues. He said that he had separated the upper and lower, and tried to pull the bolt to the rear. It came back a short distance and stuck. Wouldn't go either way. He reported that the bolt locking lugs were not rotated into the locked position, so that it should come open.
He's bringing it to me tomorrow for a look-see, but meanwhile I'm puzzled. I took one of mine apart to visualize what he was describing and cannot understand what may be holding the bolt closed. What would be holding the bolt such that the bolt carrier could not be pushed in enough for the upper to be closed on the lower? Are those boresighters made to the same dimensions as the cartridge? If so, I would think that it should pop out.
