When mounting the Modstock system, what other parts will be needed?
The Modstock system is a direct replacement stock for the existing Rifle and Carbine AR type firearms. The only time additional parts will be required is when mounting the Rifle Modstock to an early style “AR” and “A1” configured rifle. The qualified installer will need an “A2” Buttstock Adapter and Butt Cap Screw to complete the assembly process safely. Please refer to the Warning message and the Manual for detailed information before purchasing any Modstock System.
