The Hidden Screw Steel Breech Kit is now available for the 1322, 1377, P1322, P1377, 2289, Drifter!!! 362 Kit located here.

Summer 2023 Note: The limited-run Crosman 362 Heritage (a wooden-clad 100 Year Anniversary Edition) is the only pump gun I know that comes from the factory with a hidden screw breech.

For those that don't know, Crosman offers a "hidden screw" steel breech on certain models. This breech is amazing because the "front breech screw" is no longer in the pellet loading area. It's now tucked underneath the bolt which greatly facilitates easier pellet loading. If you've ever struggled to insert a pellet into the breech, you know what I'm talking about.

Anyhow, this breech has always been available, but it's only ever been compatible on the CO₂ guns (2240 2250 2260 etc). It's never been compatible on the pumpers because the main tube didn't have the proper hole and a notched hammer has never been made available (the hammer must be notched as the screw sits farther back, interfering with normal hammer operation).

Kit available as tube-only, tube + hammer (and you're going to need the hammer unless you machine it yourself) and optionally the hidden steel breech, too.

Again, you can't just buy the Hidden Screw Steel Breech for these pump guns like you can the CO₂ guns.

The option *does* exist below if you plan on doing your own machining, but all three pieces (tube, hammer, breech) are required to make the kit work correctly.

This is the 362 Kit video, but it's the exact same principle.
