What kind(brand and type) of gas block do you have on the gun Rob? What kind of buffer spring and weight of buffer is in the gun?I bore sighted it as shown in post #9. Then I sited it like it was a bolt action. I checked it again this morning and the barrel look remarkably clean for being fired 30 - 40 times. I have not ever adjusted a gas blocks or if they need adjusting. There has never has been any factory ammo through this upper unless PSA used some to test it before shipping, as I think they do.
I watched a video about one round in a mag and opening it up one turn until it locks back each time. Then another turn for colder weather. This is the problem I am having. The highest load I had rarely ejected shells and did not lock back or chamber a new round. They would reset the hammer and push the spent casing back into the chamber as they did not travel far enough backwards.
Opinions and guidance? I'll probably bring Byron up on Saturday or Sunday and make him a deer steak and have him help/show me. The Gas block has two screws on the side, one block by the hand guard. One looking to be facing the muzzle. Scope front mount is on the hand guard. So I am assuming all this needs to come off to adjust it.
Did this gun start out with a different upper on it? If yes, what barrel length, gas length, and caliber?
