I'm calling this the Pumper's Pack as it's a great addition to your Crosman 1322 1377 or 2289 Pumper.

It's also fully compatible with the 2240 2250 & 2260.

It consists of my world famous High Performance Hammer Spring and equally power-inducing Max Flow Transfer Port Bushing.

The power spring is longer and stronger than the OEM spring, offering more striking force against your model's hammer, increasing velocity.

Likewise, the Max Flow Bushing has been opened up with a .161" ream, to allow more exhaust airflow. Better breathing, better velocity. Guaranteed.

One listing, two great items, one great price.
