Hi, I shoot 3 pistols with my mp15-22 and the others are improving their weapon, mine is not competitive yet and I would like to improve my weapon. I already have an MOE-K2 + grip, Magpul CTR stock, Taccom3g Ultralight handguard, Tacticool22 Charging handle, and MTAC Burris scope. I would like a 1 step trigger that weighs more than 3 lbs, but I haven't found any that weighs more than 3 lbs. Which is the best ? Is it worth changing the barrel and the extractor? Which are the best? I would also like to know if it is worthwhile to put a compensator and which one. I know it's a lot of questions, but it's very helpful for me. Thank you very much. .
