6.4 Gas Cylinder Adjustment
For optimum performance of this shotgun, use shells with a minimum
velocity of 1200 fps and minimum weight of 1 1/8 oz. The weapon can also
be tested with the gas setting on “H” (heavy) or “L” (light) for function based
on the velocity of the load you are using. For reliable functioning with 2 ¾
shot shells, use the “L” setting. For higher velocity 3 inch magnum rounds,
use the “H” setting. If the heavier rounds fail to function with the “H”
setting, try the “L” setting with the same ammunition. Short and mini shot
shells will not function.
To adjust the gas setting, remove the charging handle by aggressively
pulling it out of the skitter tube. Place the end of the charging handle in the
gas cylinder slot and turn the cylinder to the desired position. Replace the
charging handle after use by re-inserting it into the skitter tube.
H - Heavy / L - Light
NOTE: It is recommended that shells with a velocity of at
least 1250fps be used.
H – Utilized for 3-inch shot shells.
L – Recommended for 2 ¾-inch shells.
