The BRN-10 Upper Receiver is now yours to build off of!
The BRN-10® Upper Receiver can now be purchased individually, allowing you to build out a unique AR-10® clone to fit your desires. The receiver includes the proprietary BRN-10® parts, such as the rear sight assembly and charging handle. Any standard SR-25/DPMS pattern bolt carrier group and barrel assembly will interface fine with the BRN-1®0 upper. The receiver is machined from 7075-T6 aluminum and anodized matte black.
The BRN-10® Upper Receiver only fits the BRN-10® Lower Receiver. It is not compatible with other 308 pattern receivers.
