Five interchangeable gas jet screws to apply just the right amount
of gas to work the action. Softens the recoil impulse, gives a
slower cycle time that reduces wear and battering on op rod, bolt
cam, trigger group and receiver. Lets you control case ejection
velocity, plus prevents dented case necks. Just remove the gas
jet screw for conversion to manually cycled, single shot function.
SPECS: Steel, blue, matte finish. Replaces existing gas nut with
no modifications to rifle.
