This .22 caliber short-nose bolt is steel with black-oxide finish. It's the version sold with the Crosman .22 Steel Breech Kit ( 2240 SBPK) and original to 2300KT, 2400KT and 1300KT .22 models. It's 8-32 thread and fits all the bolt handles we have listed.

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