Availability: In Stock
The Midwest Industries LR-308 Lower Receiver Block is a precision-engineered vise block built specifically for AR-10 and AR .308 lower receiver work. Whether you're building an AR-10 from the ground up, installing a trigger group, fitting a gas block, or performing maintenance on a complete rifle, this gunsmithing tool holds your lower receiver securely and safely while you work. Made from high-strength polymer, it's durable enough for the bench and light enough to move around your workspace.
The four-point contact design grips your lower receiver from multiple angles, preventing rotation or shift during critical assembly and modification steps. A dedicated trigger guard installation section keeps that area accessible when you need it, and the small parts tray catches springs, pins, and detents so nothing rolls under the bench. The mounting holes let you bolt the block directly to your workbench or attach it to a shop vise, giving you stability whether you're hand-fitting, drilling, tapping, or installing roll pins for gas blocks.
Built and assembled in the USA, this tool is built to last and designed by people who understand AR platform work. If you're a serious shooter, builder, or gunsmith who handles AR-10s regularly, having a proper lower receiver block speeds up the job and makes it safer—your hands stay free to work, and your receiver stays exactly where you put it.
