Frequently Asked Questions

What is a gas buster charging handle and why is it needed?

A gas buster charging handle is a modification designed to prevent gas blowback from reaching the shooter's face, especially when using a suppressed firearm. It seals the gap between the charging handle and the upper receiver, mitigating the unpleasant fumes and irritation caused by escaping gases.

How can I make a DIY gas buster charging handle?

You can create a DIY gas buster by applying high-heat RTV silicone to the rear of an AR-15 charging handle. Use Kiwi shoe polish as a release agent on the upper receiver, then apply the silicone and let it cure overnight to form a custom gasket that blocks gas.

What materials are required for this AR-15 charging handle modification?

You'll need Permatex Ultra Black RTV silicone, Kiwi shoe polish (as a release agent), denatured alcohol for cleaning, Q-tips, rags, a torch or lighter for slight heating, and protective gloves. Spacers are also used during the curing process.

What is the purpose of using shoe polish in this DIY gun mod?

Shoe polish, specifically Kiwi brand, acts as a release agent. It prevents the RTV silicone from permanently bonding to the aluminum upper receiver of the AR-15. This ensures that the charging handle can still be removed and operated normally after the silicone has cured.
