Does the SilencerCo GDCH Work?
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.
