I really love these base plates and they do fit well.
There is nothing wrong with the service too as I got them good and without any problems too.
Direct copy of the Tanio Koba grip set (even copied the TK engraving). Very tight fitment around mag release and main spring.
Feels stiff and fitment issues decrease with use.
The barrel nut is not 100% compatible with the 416 NGRS Marui
Productr really good quality tho
