Also been reading about over gassing on the actions. I have an idea how to fix this. Doing more reading, research. I know the gas hole, port in my wasr is huge vs AR.
AKs are over gassed by design - it’s part of the reason they have their reputation for reliability (in addition to loose tolerances and simplicity).
If you want a fairly simple way to tame the gas, I’d go with a KNS gas piston. You can get more complicated with adjustable gas blocks but that requires pressing off barrel components. Lot of good videos on the KNS.
There’s also recoil springs from Wolff and ALG that help.
