XS Sight Systems Armorers Block AR Platform Gen 2 Vise Block - Fits AR-15/M4, AR-10, SR-25

The XS Sight Systems Armorers Block Gen 2 is a purpose-built gunsmithing tool designed to securely hold AR-platform upper and lower receivers in a bench-mounted vise for assembly, maintenance, and other armorer work. Machined from aluminum, this vise block provides a stable, non-marring interface so you can work on your rifles without damaging the receiver's finish or critical surfaces.

Designed as a versatile multi-pattern tool, the Gen 2 Armorers Block accepts AR-15/M4, AR-10, SR-25, and DPMS GII pattern receivers, making it a practical addition to any AR builder's bench or armorer shop. The block clamps into a standard bench vise and supports both uppers and lowers, allowing a wide range of service, disassembly, and component-installation tasks to be performed with the receiver properly indexed.

The kit includes the armorers block and a steel detent pin for use during receiver work. Whether you are assembling a new build, performing routine maintenance, or swapping out parts, the XS Sight Systems Armorers Block keeps your receiver solidly supported so you can work with confidence.
