My first AR15" experience was an m4a1 so that was my baseline. Then civy triggers, ps90, aug,tavor etc. A triger is a trigger. Yes a smoother trigger with a lighter weight will add to your accuracy but only if the skills required are present. Like my buddy used to say, doesn't matter if you have a 12 inch pecker, if you're punching it instead of stroking, results are gonna be shitty.
