Crosman 1322 / 1377 / Drifter Pump Arm Insert

This is a stiffening liner for the current narrow Crosman 13xx/Drifter forend. It completely fills the hollow space between the forend shell, the metal lever, and the air tube. Helps eliminate that toy-like feel when pumping and holding the forend. Reduces the clapping noise.

Carefully check that the pump arm closes and stays in place, but do not force the arm closed otherwise damage may occur to the air tube.

This fits a newly purchased Crosman Drifter (2024) well, with no modifications needed.

Print in the orientation as-is, with supports.

Printed with Atomic black PLA.
