Professional-Grade Armorer's Block for AR Platform Rifles
The XS Sights Armorer's Block is engineered to simplify AR platform maintenance, assembly, and modification. Whether you're a professional gunsmith or a dedicated enthusiast, this vise block provides a secure, stable platform for working on your rifle.
Versatility Across AR Platforms
Unlike single-purpose blocks, the XS design accommodates multiple AR configurations:
- AR-15/M4 receivers — the most common platform
- AR-10 receivers — larger format rifles
- SR-25 pattern rifles — precision platforms
- DPMS GII receivers — alternative designs
This flexibility means one block handles nearly every AR pattern modern sporting rifle in your shop or safe.
Robust Construction
Manufactured from 6061 T6 aluminum in the USA, the block delivers the durability and precision you expect from XS Sights. Integrated locking pins secure the receiver firmly in place, preventing movement during critical work.
Practical Design Features
The block is engineered to fit securely in standard bench-mounted vises. For AR-10 lower receivers, XS offers an optional 3D-printed adapter plate—available for purchase or home-printing if you prefer.
Important Limitations
This block is not compatible with AR-pattern rifles chambered in .300 Winchester Magnum or 12-gauge shotgun configurations.
A single, reliable solution for serious AR work.
