I have a Norinco AR-15. The trigger seemed okay at first, but now it feels very heavy. I have a couple of other AR's and the trigger feel smooth and crisp by comparison. Sometimes the Norinco trigger is so heavy and gritty you could stop the pull half-way and the trigger won't move or after you pull the trigger you might have to push it forward to reset. The pull feels like it's 10-15 lbs although I haven't be able to measure it. Anybody have any idea what caused this? I've seen this once before believe it or not on a stock C7A2. Any suggestions on how to fix it?
Cheers!
