Midwest Industries Upper Receiver Rod for AR 15

All-in-one Lower Receiver Block For .223/5.56 Builds

The Midwest Industries AR-15 Lower Receiver Block is an innovative tool that combines the traditional lower receiver block, gas block roll pin, and, magazine vice block into one polymer unit. It’s the ultimate assembly tool for gunsmiths and building enthusiasts to help AR-15 builders to save money and time, compared to using multiple tools.

The MI Lower Receiver Block utilizes either the .223 Remington/5.56 NATO or the .308 Winchester/7.62 NATO AR receiver platforms making the most tedious tasks in building an AR-style firearm fast and simple. It can also be mounted to a workbench, or used in a vise and hold a lower receiver by the magazine well.

Most Ideal Tool For Building ARs

The Midwest Industries AR-15 Lower Receiver Block features a gas block roll pin installation section, a trigger guard installation section, a fire control pin assembly, and many other applications outside of its classic use, making it the most ideal tool for building an AR-15 rifle.

This model is made specifically for the .223 Remington/5.56 NATO. If you need one for the larger AR-308, SR25, and AR-10 patterns, click here.
