About a week ago, I finally recieved my PDI hop up for my CA M24 from Redwolf Airsoft. After about a half hour to an hour after school every day, it still is not impressing me. The shots are relatively centered, but one shot will go dead center; the next will go wide left, the next slightly right, and the next dead straight again. I have the following installed: Madbull 6.03 Version II tightbore, Bravo seventy degree bucking, and I'm using bioval .3g bbs. (These aren't all my upgrades, just the upgrades I feel relative). I have a Laylax SP170 installed as well. I have a feeling I just shouldn't have listened to the employee at Precision, and I should have gone with the silicone hop up instead of the bravo. Any suggestions on how to solve this issue?
