is a special "hidden rear screw" breech with the front breech screw
hidden underneath the bolt. It is a genuine Crosman product.
Shorty version of this breech
is also available.
For this breech to work
with your gun, your main tube must have the rearward screw hole. Most
tubes have BOTH screw locations, with one obviously going unused.
OEM notched hammer (required) is included that fits 22xx tubes (2240
Notched hammers do not
exist for the 1377 1322 2289. You would have to notch your current hammer
yourself (or have me do one for you) AND you would have to drill and
tap the rearward hole, too.
These breeches are made
of solid steel and provide strength, durability and accuracy over
their plastic counterparts.
Best of all, however, is
the addition of factory-milled 3/8" dovetails, which allow the
installation of any scope with 3/8" dovetail rings.
If you feel
uncomfortable performing the upgrade, I will perform the upgrade for
free, providing you pay for shipping both ways.
Q: Why is
Crosman making two different hole locations?
A: The new location hides the screw, hole and divot
underneath the bolt at all times.
This keeps the pellet from getting jammed in the depression during
Q: Will this
breech fit my gas tube?
A: Remove your current breech. If there are two breech
holes close together
(one of which your breech screw just came out of and the other of
which is not used),
then it will work. Or, if you're handy and don't have a second
hole, drill and tap one out
(see photos). Normally, 2240, 2250, 2260, 2300 and 2400 tubes have
both holes. 1377, 1322 and 2289 do not.
