Adjustable gas pistons for other AK derivatives

#1
Hello all, has anybody looked at the KNS Precision adjustable gas piston and then started thinking “I wonder if this will go into my old Valmet / Galil / Golani rifle?” I cannot get my hands on stripped pistons to do a side by side comparison, so hoping that somebody here has done just that and now has a better warhorse?
Any thoughts about the next evolution with KNS doing the same for the new IWI ACE rifles, or even a similar idea to aid in suppressing the 5.56 Tavor / X95?
Cheers Larry
