STANDARD STEEL BREECH for 13XX & 22XX
This is the standard Crosman steel breech, same one issued with the Crosman Steel Breech Kits 1377SBPK & 2240SBPK. This is a striped-down breech with the barrel set-screw, no other parts included. The breech plug, bolt and bolt handles are listed separately. This breech fits Crosman 13XX & 22XX models, will not fit Discovery or Maximus without modifications to the tube and valve on those models. It works with standard and notched hammers and is the easiest to install and disassemble. It has a notch for mounting the Crosman LPA rear sight and a scope rail for mounting other sights and scopes, the rail fits most rings and mounts for 3/8" and 11mm. This is the only breech listed that fits pump models 1377C, P1377, PC77, 1322C, P1322, 2289G Backpacker and 1300KT unless you install our Custom Notched Hammer for 13XX and drill/tap the mounting-screw hole on the tube in the correct location, the listing for that hammer explains where to drill and what thread-size the hole needs to be.
All Crosman/Benjamin steel breeches require a 3/4" long rear breech screw. The 13/16" screws that are standard on plastic breech models are too long for a steel breech. The longer screw can damage the hammer spring or prevent it from working correctly. It will also hit the threads on the adjustment knob of our custom Magnum Adjusters. For 13XX models our Magnum Adjusters include screws for the breech and trigger frame that fit correctly, we have spare screw kits for those listed in our UPGRADE SCREW KIT listing.
The standard rear sight original to plastic breech models does not fit any of the steel breeches.
