I am looking to upgrade to a long steel breech on my new Crosman 2240, and use the .22 barrel. In reading other posts, it looks like the parts list is as follows:
as22500-a013 breech
as2250-020 plug
88-089 set screw
as2250-015 rear breech screw
2300-034 Bolt, Nickel, Long Nose
1761-018 Handle, Knob
I think this is the right breech (rear screw), but I am not sure about the bolt. Is the same bolt used for both .22 and .177?

different bolts on .177 and .22. you can use a disco .22 which has a longer probe thingy.

Does your 2240 have the rear screw, is it hidden under the bolt? I have a new two week old 2240 it has the front breech screw. And as said above you will need a .22 bolt 2261-002 is a long nose nickle .22 cal. and handle AS2250-009 2300-034 is .177

Thanks for your replies!!
So, on the plastic breech on the 2240, the breech screw is at the front of the loading port and is exposed when I pull the bolt back. If that is a front screw, then I think I need the AS2250-025 breech?

Yes that would be called the front screw location.
I am still not sure what breech part number has the front screw location. There is conflicting info around.
The part number used to be 2300-008 now it seems it MAY be the AS2250-AO13 As far as I can tell the AS2250-025 is for the rear screw location.
I looks like crosman did not change the drawings to show the rear screw location just a different part number for the new rear screw location.

also like i mentioned in the other thread, there are variations on what type of sight will fit each kind of breech. easiest to confirm by talking directly to whatever vendor you go with. besides crosman there are several other vendors that make breeches for these guns steel, aluminum, brass...with different configurations. most will cost more than the crosman breeches though.

Yes, I have seen a long breech, short breech, hidden screw, and exposed screw breeches AND most recently a breech that did not have the transverse dovetail for the LPA mim Sight cutout.
Pretty sure they were all listed as Crosman parts.

The top breech is a Discovery/Maximus breech. It fits 1740, 2240, 2250, 1760, 2260, all 2300 models and 2400KT. It has a full scope rail which makes it the best fit for scope rings and Williams sights.

One more thing I have read. While the modern made 2240 may have both front and rear screw holes in the main tube, it is best to verify.
The rear / hidden screw model requires a notched hammer be used for clearance. While the breech with the front STANDARD location so this will NOT require notched hammer.

Great pictures. Now all we need is someone to match the part numbers to each variation. And make it a sticky.

Scott, I think all the new 2240's have the notched hammer in them now, (all of the 4 I bought did). You can use a front or rear breech screw location on the 2240, so a disco/maximus will fit as well as a CCS or a front location screw. Assembly is different though as you must assemble in a different order between rear and front screw designs.
-
Well dang, Now I am going to open my 2240/1740 up before I order the breech and find out!
Interesting that I have heard the rear screw (hidden) version called a CCS or 2300 piece, but my 2300KT has the exposed forward screw breech. :o
-
That's because a 1300KT is built on a 1377 tube and does not have the rear screw hole in it. It uses the front crew hole breech that has a sight notch in it. whole different set up from a 2400.
OOps my bad, I thought I read 1300 not 2300. I don't know why it wouldn't then unless it is an older one with out the notched hammer design in it.

It was used when I bought it here on the classifieds and I do not know the actual age... ::)
-
It could be the old style then. It's pretty easy to check only takes a couple minutes to get 'er opened up.

Thanks for the help so far.
I found this post over at the Crosman Air Pistol Owners Forum:

A guy at GTA just went through the breech types and after getting the wrong one did get the correct part #s.
Long steel breech w/rear screw location: AS2250-025
Long steel breech w/front screw location: AS2250-A013
The 22xx tubes have both front & rear screw holes in the tube. The 13xx tubes have only the front screw hole. (end quote)
And this quote on GTA:

You are correct as far as we know the AS2250A013 is the right one for the forward hole.
If you are still not sure you can order the breech kit 2240SBPK $34.95 plus shipping (end quote)
So, it looks like the AS2250-A013 breech should be the one I need. If I somehow wind up with the rear screw breech, I guess I will just tap the hole and go with it. I recall that the striker was notched so it should work.
I have been having second thoughts about caliber. Does anyone know what the p/n is for a 7.5 inch .177 barrel? The 1740 EVP says 1740-001? If I can't find one of those then I suppose get the 10 inch 1377 barrel.
Also, do the extended bolts come with an o-ring or do I need to order one of those?
