So, I was wondering what the best o rings for an AEG Piston head were. The stock ones aren’t very ideal, and trying some ones from Amazon, but my FPS went down by 35 in a few weeks so guessing they aren’t working very well (was a 15/16” OD x 3/4” ID x 3/32” width). Was looking at black blitz X Ring. Are they very good, otherwise what else?

Thanks!
