PRI’s M84 Gas Buster Charging Handle is one of the most popular charging handles on the market and is known worldwide for its incredible benefits for shooter comfort. PRI uses a patented internal safety device that protects the shooter from dirt, oil, and blowback gas that can impede visibility when it matters most. Anyone who has shot a suppressed AR-15 or AR-10 knows just how difficult it can be to keep on target when residual gas is blown into your eyes. Safety glasses do little to combat the sting, and without wearing full-size ski goggles to the range, the Gas Buster Charging Handle is your best fix. Gas Busters aren’t just convenient though—they’re absolutely rock solid. PRI machines them from T6 7075 aluminum with a hard coat anodization. That’s why countless special operations teams choose this charging handle above all others.
