Hey thanks for the post. To clarify I was only using one mag with 2 different kinds of ammo and using that same mag the 556 worked great and the 223 worked somewhat. You mention gas issues but if I tried it with one round in the chamber and it fired and locked the bcg back, wouldn't that mean the gas is good? If in wrong please correct me as I'm an ar15 newb. Thanks.
