This .177 bolt and handle set is heat-treated 410 stainless steel. It's extremely strong, developed to handle the stress of our .045" WD hammer spring and power adjuster set at full tension. These were engineered from scratch to fit and work flawlessly. The handle is removable, thread size 8-32.

The long-nose bolt is shaped and sized for maximum air flow. It fits well with all types and sizes of pellets.

 The handle is 1.25" long from end to end. It extends 1-1/16" from the bolt. This length is in-between the standard Crosman short and long handles and makes an excellent upgrade for either. These parts thread together to work with plastic or steel breeches.

 To convert a .22 model to .177 you only need to install this bolt and a .177 barrel.
