I have an adam arms upper in 545x39, took it out to day
and it was like a bolt gun. tryed it on all gas setings
the bolt would travle far enough to throw out the case and cock the weapon but not far enough to pick up another round.
can you guy point me in the right direction
i did install the heavy hammer spring provided in the kit.
thanks in advance for your help.
