I am running a bear creek upper and psa lower as I was just wanting a cheap beater I could silence. I shot some armscore ammo that would shoot every 3-4 and then jam…I then switched ammo to shoot federal fmjs I think American eagle ammo. It shoots flawlessly. I just tried sighting it in with 200 grain stealth subs and it wouldn't feed the cartridge after each shot. I am using .556 p mags. What do y'all think is my issue?
