Item Description Use Commercial Ammunition safely in your M1 Garand without worrying about your operating rod! The Ported Gas Plug™ requires no adjustments. Install it and forget it! Lowers gas cylinder pressures to levels safe for the M1 Garand Reduces bolt speed when using commercial ammunition to reduce the wear and tear on the receiver Installs with a standard 1/4 socket extension. No special tools required! Our custom gas screw has been designed to help you safely shoot commercial ammunition hassle free in your M1 Garand. Our gas screw has a tuned port that delays the operating rod for several microseconds and lowers the peak gas cylinder pressure by over 30%! Unlike a vented gas screw, ours requires no adjustments and is ready to use right away. The gas screw can be installed using a standard 1/4 socket driver! Our Ported Gas Plug™ does NOT vent gas like a vented gas screw. The secret is the hollowed out area in the base of the screw which increases the initial volume of the gas cylinder. By increasing the volume, the peak pressures are reduced without the need to vent the gas. --> Payment We only accept PayPal payments on eBay.
