Midwest Industries LR-308 Lower Receiver Block - Precision Machined AR-10 Lower Vise Block$41.95
Availability: In Stock
The XS Sights Armorers Block is a universal receiver vise block built for AR-15 and AR-10 platform gunsmithing. Whether you're assembling your first AR, swapping uppers, installing a new trigger group, or performing field maintenance, this tool holds your receiver securely in a bench vise so both your hands stay free for the work. Unlike single-purpose blocks that lock you into one receiver size, the XS design accommodates AR-15, AR-10, SR-25, and DMPS GII pattern receivers—making it a genuine one-block solution for any serious AR builder or armorer.
Built from 6061 T6 aluminum and made in the USA, the block provides the rigidity and durability you need for consistent, repeatable work without marring your receiver. It ships with locking pins to keep your receiver seated during assembly and modification. The design is straightforward: clamp the block in your vise, slide in your receiver, lock it down, and get to work. For AR-10 users who want to brace the mag well, XS offers a 3D-printed adapter plate (sold separately or available for home printing) to extend compatibility further.
If you own more than one AR platform or build rifles as a hobby, this block pays for itself in convenience and time saved. It's the kind of tool that lives on the bench and becomes part of your regular workflow—no fussing with makeshift solutions or buying multiple blocks for different rifle sizes.
Yes. The XS block is designed to accept AR-15, AR-10, SR-25, and DMPS GII pattern receivers, so a single block handles multiple platforms.
The block comes with pins to lock your receiver in place during assembly and maintenance.
No. This block is not designed to accommodate .300 Win Mag or 12-gauge AR-pattern receivers.
The adapter plate is optional. It's sold separately and is designed to allow bracing in the mag well of AR-10 lowers if you prefer that method of support. The block functions without it for standard vise mounting.
