The XS Sights Armorers Block (brand part no. AR-7002AB-1) is built to hold an AR-15/M4, AR-10, or SR-25 receiver securely in a bench-mounted vise for assembly, modification, and maintenance work. Machined from 6061 T6 aluminum and made in the USA, it’s designed with the versatility to work on nearly every AR-pattern modern sporting rifle rather than fitting only one specific style. Locking pins are included to secure the receiver in place, and an optional 3D-printed adapter plate is available for bracing AR-10 lowers in the mag well. Note that it will not work for ARs chambered in .300 Win Mag or 12 gauge.
