I have JE recoil reduction system (i maybe will later by JP recoil reduction system) and i want to use it with piston kit from superlative arms.

those of you who know about recoil reduction systems are aware that there is a long guide rod which literally enters the BCG during a moment when BCG travels back after shot is made. that is with gas systems.

im curious if there are any potential conflicts of operation when same recoil reduction system is used with piston kit, specifically one from superlative arms?

This shouldn't be an issue if you use a standard one of it's a middy/carbine. Make sure you tune the gas properly.
