The Rise Armament AR-15 Anti-Walk Trigger Pins can give an extra level of security when installing your triggers. Pin diameter is .154", with a torque spec on the screw of 11 inch-pounds maximum; 8 inch-pounds of torque are recommended. Note: The external width of AR receivers varies in the trigger/hammer pin area, depending on the manufacturer. If the pins are too long for your receiver, you may shorten the pins a small amount by carefully filing material evenly from both ends of the pins. However, this is not required. Longer pins will not affect the function or performance of the rifle. Mfg: Rise Armament
