PRI Gas Buster Charging Handle

The PRI M84 Gas Buster represents the original patented solution to gas blowback in AR-platform rifles, earning safety approval and adoption by the US Marine Corps for suppressed weapon systems. Constructed from 7075-T6 aluminum with hard coat anodization and featuring a steel latch, the Gas Buster uses special channels machined into the top and bottom surfaces to divert harmful gases, oil, and dirt particles away from the shooter's face and eyes. This patented internal safety device significantly reduces the eye-watering gas blasts that plague standard charging handles when shooting suppressed rifles or short-barreled weapons.

The Gas Buster is available in multiple latch configurations including Combat latch and Big Military latch options, with both ambidextrous and standard variants to suit different shooter preferences and rifle configurations. The charging handle is compatible with AR-15 carbines and pistols, with separate models available for AR-10, SR25, and DPMS-pattern .308 rifles. Available in black and FDE (Flat Dark Earth) finishes, the Gas Buster maintains the visual profile of a traditional charging handle while incorporating the gas-diverting channels that define its performance advantage.

Real-world use in military and law enforcement applications confirms the Gas Buster's effectiveness at redirecting gas away from the shooter during suppressed fire. The system works by creating a more effective seal at the charging handle interface and channeling escaping gases to the sides rather than directly back toward the shooter's face. Users report dramatically improved comfort and reduced eye irritation when shooting suppressed, making extended training sessions more tolerable and maintaining better situational awareness. As the original gas-defeating charging handle design, the PRI Gas Buster carries both historical significance and proven performance credentials.
