| Does anyone know if the New Frontier Lower for Glock magazines will work with an Olympic Arms upper? |
|
Work as in physically fit onto, yes.
OA uppers feed from the very front of the magwell, not the center like Colt system and derivatives. If there is a feed ramp built into the upper, it may need to go away to clear the OA bolt assembly. The ejector may need to be removed, as it is redundant to the OA upper's ejector. The OA upper will likely not support any part of the NFA bolt hold-open, at least not without modification. |
