    My friend has a WeTech GBB scar. He is looking to buy the RA-Tech NPAS Valve system. But we are not sure of it is compatable with the opwn bolt system? Any help would be greatly appriciated.

    Do you have a link? it will say (open bolt) or (closed bolt) on the description. its really self explanatory.

    if you have an open bolt, and buy a closed bolt npas, something is wrong with you
