I retrofitted it with a standard A3 stock and put a PCS heavy buffer in that. That has been the best solution so far for me. LOP feels perfect.

HK21 pad works well. Hell, the G3 doesn’t kick that hard, even on full auto.
I'm with ghosthk, I don't think it recoils that hard. Maybe some shooters are too used to the .223 AR and expect the same experience.
