[QUOTE="Masczek, post: 2844224, member: 100797"] I tried the gun out this afternoon, here's what I found: With 2 rounds in the magazine, the bolt seems to short stroke. Sometimes it will eject the spent case at the 4-5 o'clock position, sometimes it will barely unlock from battery. It never picks up the next round, and I don't have a bolt lock installed yet, so it don't know if it will lock back on empty (I'm guessing it probably won't). I see these symptoms through all the adjustments I made with the gas block, even with it all the way open, it acts like it's not getting enough gas. I believe I'm on the right track. My theory is that the gas port is just too small, even with the gas block open all the way, the port is just not letting enough gas through. I'm debating on opening up the gas port around .073" but don't want to go too big too quick. What do you all think? [/QUOTE]
