The SilencerCo GDCH (Gas Defeating Charging Handle) aims to reduce gas blowback to the shooter's face, particularly when running suppressed on AR-15 platforms. Testing indicates it significantly mitigates gas to the face, even with a short-barreled, suppressed 7.62x39 AR, though some smell and side-venting gas may still be present. The design features a rubber seal at the rear to improve its gas-blocking capability compared to standard and other aftermarket charging handles.

Quick Summary

The SilencerCo GDCH is designed to reduce gas blowback to the shooter's face on suppressed AR-15s. It features a rubber seal and a tighter fit against the receiver. Range tests show it significantly mitigates gas, though some side venting and smell may persist.
