This guide details the process of installing a Dead Air muzzle brake on an Aero Precision M5 AR-10 upper receiver. It emphasizes the importance of using Dead Air shims for proper timing and alignment, especially if planning to use a suppressor. The video demonstrates the trial-and-error shimming process and provides the manufacturer's recommended torque specifications.

Quick Summary

Install a Dead Air muzzle brake on your AR-10 using shims for precise timing, especially for suppressor use. Avoid crush washers, as they can cause misalignment. Torque the brake to 25-35 ft-lbs with a torque wrench and 3/4 inch crowfoot wrench for optimal alignment.

Frequently Asked Questions

What tools are needed to install a Dead Air muzzle brake on an AR-10?

You will need a torque wrench, a 3/4 inch crowfoot wrench, and the Dead Air shims specifically designed for timing muzzle devices. A vise is also essential for securing the upper receiver during installation.

Why is it important to use shims instead of a crush washer for muzzle brake installation?

Shims are crucial for precise timing, especially if you plan to attach a suppressor. Crush washers can deform and misalign the muzzle device, potentially causing baffle strikes on a suppressor, which shims help prevent.

What is the recommended torque specification for a Dead Air muzzle brake?

According to Dead Air, their muzzle brakes should be torqued to a range of 25 to 35 foot-pounds. It's important to use a torque wrench to ensure you are within this specification for a secure and correctly timed installation.

How do you achieve proper timing for a muzzle brake?

Proper timing involves using shims to adjust the rotational position of the muzzle brake until its ports are correctly oriented, typically upwards. This is often an iterative process of adding, removing, and re-threading the brake with shims until the desired alignment is achieved.
