The White Label Armory Gas Key is designed to provide a secure and efficient interface for directing gas from the gas tube into the bolt carrier group. Ideal for replacing a worn or damaged key or completing a custom BCG assembly, this component ensures the airtight seal necessary for reliable cycling and consistent bolt velocity. Manufactured from high-strength steel and built to meet standard Mil-Spec requirements, the gas key is precision-machined for a flat mating surface, a seamless fit on the carrier, and long-term durability under extreme heat and pressure. Utilizing a high-quality gas key helps prevent gas leakage, maintains the proper timing of your rifle’s action, and contributes to the overall cycle-to-cycle reliability of your firearm.
