Are you talking about accuracy or ftf's? If your using a bolt gun that would explain the ftf's.
yeah, I thought I might need to clarify after I posted.
Shooting from an AR, accuracy was better with the AE Tactical than the Norinco as well as more reliable.
I loaded equal LAR mags, side by side targets from a rest at 100 yards, I got tighter groups with the AE than with the Norinco. We're not talking drastic, but noticable. I was getting 3-4" 10 round groups with the AE and with the Norc it was 5-6"
It was weird for the FTF, waited my 30 seconds, nothing, ejected the round, didn't look like a light strike, stuck it back in the chamber and pulled the trigger again and it went bang.
I also noticed with the Norinco, out of LAR mags, full 10 rounds, bolt open, my AR had some trouble stipping the first round out of the mag. Maybe they are actually 5.56 and just that much larger of a round in the LAR mag to make it tight enough to need the forward assist in order to load.
