Hello, I’m currently beginning a 6mm ARC build and am wondering what upper lower to go with, I’m currently leaning towards a zev billet set because most places I’ve read show they have some very tight tolerances and should be a good pair for a longer range build like this. But wanted to see if Anyone here has an opinion or a suggestion. Thanks! Not skimping on parts and putting good money into this so want it done right the first time haha.
