Mil-Spec Aeroshell 64 / 33MS Barrel Nut Grease from AT3

Aeroshell 64 (formerly 33MS) stands as the high-pressure grease trusted by the US military for attaching barrel nuts to M16 and AR-15 receivers. This lithium-based grease acts as a barrier between steel and aluminum, preventing corrosion and binding on your rifle over time. And if you’re a frequent builder, not only is this a must for your workbench, but a single 1/2 ounce jar covers multiple builds!

How to Use Aeroshell on Your Barrel Nut

One of the great things about Aeroshell, is that you don’t need to use a lot to get the benefits. Using a small amount of grease (think pea-sized), work the grease into the threads of your upper receiver. Then, thread on your barrel nut until tight. Remove and install the barrel nut a few times to work in the grease before putting on final torque. Simple!

Features

Approved for MIL-G-21164D for M16 and M4 rifle barrel nut grease
