Gas Busting Charging Handle Showdown

Published on November 1, 2022
Duration: 16:14

This review compares several AR-15 charging handles designed to mitigate gas blowback when shooting suppressed. While many offer solutions, the effectiveness diminishes after initial rounds. The Aero Precision Breach and Radian Raptor-SD are recommended for their balance of performance and reliability, despite some handles like the SilencerCo GDCH showing durability issues.

Quick Summary

Suppressors increase AR-15 back pressure, forcing gas into the receiver and out the charging handle slot. The Radian Raptor-SD and Aero Precision Breach are recommended for suppressed shooting due to their balance of performance and reliability, though effectiveness can decrease with sustained fire.

Frequently Asked Questions

What causes gas blowback when shooting a suppressed AR-15?

When an AR-15 is suppressed, the suppressor increases back pressure. This forces more gas through the gas tube into the bolt carrier group, and excess gas escapes through the gaps in the receiver, including the charging handle slot, leading to gas directed at the shooter's face.

Which AR-15 charging handles are best for suppressed shooting?

The Aero Precision Breach and Radian Raptor-SD are recommended for their balance of performance and reliability. Other options like the Geissele ACH, PRI Gas Buster, and Strike Industries T-Bone offer different design approaches to gas mitigation.

Are gas-defeating charging handles always effective?

While helpful initially, the effectiveness of gas-defeating charging handles can diminish after 5-10 rounds due to general gas buildup in the air. Some designs, like the SilencerCo GDCH, have also shown durability issues with components like roll pins.

How does the Radian Raptor-SD mitigate gas blowback?

The Radian Raptor-SD charging handle is designed with angled cuts and vent holes along its shaft. These features help to redirect the escaping gas away from the shooter's face, reducing the 'gas to the face' effect experienced during suppressed shooting.
