I have a M11 that is being all wacky on me. I was shooting some TM .25s through it and the hop-up was dialed way high and the bbs would curve up almost instantly. so i slowly dialed the hop-up the other direction until it was completely off, but the bbs didnt show any change in their flight path. so i load up a different mag with the same bbs, and now it shoots down like it should. This is pretty much how it preforms. It seems that with one magazine it shoots like it should and the other shoots up no matter what the hop-up is set at. My question is, could a leaky valve or some sort of mag defect cause this difference in preformance? any help would be appreciated.

had the same problem on mine, and the concentric hop dial was stuck, so when I turned it to off, it actually turned the barrel and made the BBs hops to the left or right.

thats a dam good question, my mac did the same thing. id like to know aswell
