Product Description The SilencerCo Gas Defeating Charging Handle (GDCH) is a precision-engineered upgrade for AR-15 platforms and SIG Sauer MPX configurations, designed to significantly redirect blowback gas away from the shooter. At its core is a proprietary O-ring seal that blocks gas from escaping at the most prominent point of egress, dramatically reducing the amount of gas blown back into the shooter&';s face for a more comfortable and enjoyable shooting experience. Machined from aircraft-grade 7075 aluminum and finished in a durable black hard-anodized coating, the GDCH delivers rugged reliability alongside a clean, low-profile integration. The ambidextrous design, aggressive texturing, increased lever throw, and strengthened latch engagement make this a standout upgrade for serious shooters. Each unit ships with one O-ring pre-installed and one spare for added convenience during extended use.
