    G4 RSA Adapter

    Posted by Bob on 31st Jan 2022

    Good quality product, however it does not work well in the G41 using a ZEV ss guide rod.. Slide does not fully retract when paired with the ZEV stainless guide rod. It binds about 2/3 of the way back. I tried it with some other SS guide rods and it works a bit better. It is not the fault of the adapter, it's a guide rod and spring issue in the G41. In other gen 4s this would be ideal and an excellent choice for tuning your RSA to your loads.
