Availability: In Stock
Building or maintaining an AR-15 doesn't require a gunsmith's bench setup—the Midwest Industries AR-15 lower receiver block brings shop-grade holding security to your workbench. This high-strength polymer block lets you safely clamp and position a complete lower receiver during assembly, disassembly, and repair work, freeing both hands for the job at hand. Made in the USA, it's engineered to handle the repetitive setups involved in AR builds and maintenance without damaging your firearm.
The block accommodates standard AR-15 lower receiver dimensions and provides multiple work surfaces for different assembly tasks. Its design includes dedicated sections for gas block roll pin installation and trigger guard work, reducing setup time between operations. The integrated small parts tray keeps fasteners and springs organized and within reach—essential when you're working with the dozens of small components that go into a lower receiver assembly. Whether you're a first-time builder or a seasoned tinkerer, this tool simplifies the clamping and holding challenge that trips up most home gunsmiths.
The block attaches securely to your workbench through mounting holes or grips in a vice using four contact points, so it won't slip or rotate mid-task. That stability matters when you're driving pins, installing springs, or fitting trigger groups. At just 12 ounces and compact enough to store in a toolbox, it's a single-purpose tool that earns its place in your AR maintenance kit.

The polymer construction and broad contact points are designed to hold a lower securely without marring the finish. Always ensure proper clamping pressure to avoid over-tightening.
