I definitely need more practice; everyone does, you can never get enough IMO.
The AR-15 actually had a crazy stiff trigger that I was not used to either; you could pull it back and just when it felt like it should fire, you still had to pull the other half to fire. didn't like that at all, my dad has tricked out all my guns with hair triggers and it gets hard to shoot a gun you have work at pulling the trigger.
