Pump Arm Forend Liner, Crosman 1322 1377

thingiverse

This is a stiffening liner designed specifically for the current narrow Crosman 13xx forend. It fills the hollow space between the forend shell, metal lever, and air tube perfectly, eliminating any empty feel when pumping or holding the forend. The liner also reduces the clapping noise associated with these models, providing a solid surface for attaching an adhesive felt pad if needed without altering the exterior appearance significantly. To install the stiffening liner, simply remove the two screws that hold the forend to the pump arm. Insert the liner into the forend shell and slide the pump arm into the groove in the liner, aligning the screw holes before replacing the screws securely.
