Author Topic: which steel breech converting 1377 to 1322?? (Read 10693 times))

oldnamvet · « **on:** March 12, 2014, 11:18:39 AM »

I am trying to convert a 1377 over to a 1322 carbine. I ordered all the parts after a lot of reading on the forum and advise from another member. BUT when I got the long steel breech, the mounting screw sholes, or rather the screw hole in the opening of the breech, did not line up. The part I ordered was AS2250-025 and the placement of the holes is shown in the picture (steel breech on top) compared with the plastic breech I removed from the gun. I sent the part back to Crosman and they checked and assured me that I had gotten the part number I had ordered. I was referred to a local expert but he was not able to find any part numbers for what I wanted, only plastic breeches. So I wonder if anyone else has had this problem and if they knew what part number was needed.

I have several breeches with the old screw location. I find there are no issues with .22 pellets hanging up, but with .177 they hang up quite often, or at least make closing the bolt rough. I'd like to get one of the new breeches, but so far all I've been shipped were old ones. How can you know you are getting a new one? Is the part number different?

I just went through this yesterday. I ordered the same part number as you and discovered the same problem. You can't use that breech on a 1322 or a 2289, you need the right breech. I called Crosman and described my problem. I told them that I needed the forward hole breech same as what comes in the CR-2240SBPK breech kit. You probably don't need the whole kit - just the breech in the kit unless you just want the bolt and other parts in the kit anyway. Difference in price between just the breech and the breech kit is $10 - $35 for the kit and $25 for the breech. $4 shipping either way.

They will take back your incorrect breech for credit and will credit your card when they receive it. They'll give you instructions but basically just ship it back with a copy of the packing list marked "Credit" and you should be all set.

Cheers

Also - I did not get the part number but I will follow-up post next week when they arrive. Ordered 2 breeches for both my 1322 projects.

oldnamvet and others, here is the link on Crosman's site for manuals and exploded views with part numbers. Choose your manufacturer, pistol or rifle, or the one you want a part for from the list.

I pulled my "new" breech with rear screw location off a custom shop 2400KT. I tried to mount it on a 2289, but found that it wasn't drilled and tapped for a rear screw. My 2260 Heritage had both holes though. Then I found out the hammer was hanging. Thanks to fellow forum members' I found out that to use the rear screw location you also need the slotted hammer.

Hi guys

That part number is shown for a 2300s (AS2250-025) and if you look at the drawing it shows a forward screw, does this mean the drawing speaks with forked tongue. LOL

F7FTIGERCAT · « **Reply #7 on:** March 12, 2014, 05:15:07 PM »

This is getting very interesting I just looked at the early and late 2300s the early one shows a ( 2300-008 ) and the late one shows a (AS2250-025)
The drawings both show a forward screw but one wonders if Crosman changed in production because of the pellet hangup issue or maybe just because.
If this is the case they NEED to note it on the drawing so this will not happen !!

as some one who has built machinery the size of house from drawings...

I can it must be MUCH easier to update a part number on an exploded drawing than it is to update the drawing to match the changes that go with the new part number..given the hundreds of times< in my personal experience, that the new parts didn't match the old drawings...

Seems like Crosman did a change for the 22xx size tubes. Most have both breech screw locations as of now. I don't know why they don't do it for the pumper tubes too,sure would save some headaches.

F7FTIGERCAT · « **Reply #10 on:** March 13, 2014, 03:59:11 AM »

Yes the 22xx tubes have two holes but only one is threaded in both of mine ( the forward one)

Did not know they made a slotted hammer. I could probably do that myself. Even so, I don't have the equipment to drill a new hole in my pump tube accurately enough to use the rear hole breech. Sure would like to try it though because many pellets other than dome shaped hang up on that breech screw.
I sense another cottage industry opportunity here. Rear hole breech pumper kit including modified tube, slotted hammer, and rear hole breech.

I just talked to Crosman to order the correct breech. The part number of the steel breech from the 2240SBPK kit is AS2250-A013. With shipping the cost is about $30. Heres hoping it has the breech screw at the front of the breech to match my pistol.

F7FTIGERCAT · « **Reply #13 on:** March 13, 2014, 03:47:11 PM »

Tom

That one should be good to go, it is on of the numbers I came up with after the mishap with the first one One can hope all will be well.

We await your yay or nay

I think it would be great if somebody made a basic, anodized black, aluminum 13xx platform breech with Picantinny rail instead of dovetail. Eliminate the need for adapters, firm up your barrel mount and expand your options for a sighting solution. Crosman could make them from steel and probably sell quite a number.

I want to be sure I have this straight, as I have a 2300KT with a long Crosman steel breech and a 1377C with plastic breech The 2300KT has the rear screw location and the 1377C has the forward location of the screw. As I read this thread, the AS2250-025 breech now comes with the rear screw location, while the AS2250-A013 has the forward location. Is that correct? I want to order the correct breech for my 1377C.

Thanks

F7FTIGERCAT · « **Reply #16 on:** March 13, 2014, 06:13:58 PM »

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

Really to convert your 1377 to a 1322 all you need is a 22 bolt and o ring and a 22 barrel The steel breech just makes it a superior package all round

RAKonTour · « **Reply #17 on:** March 13, 2014, 06:23:16 PM »

Thanks for confirming the part number. I'm actually not looking to convert the 1377 to a .22 - just want to improve the gun and add a red dot sight, keeping the .177 caliber.

F7FTIGERCAT · « **Reply #18 on:** March 13, 2014, 06:45:37 PM »

Very good, don't forget the rear breech plug AS2250-020 rear screw AS2250-015 and barrel set screw 88-089 something else you might think of is a long probe bolt you can get one from Crosman for $3.30 in 177 the part number is 2300-034 and 397-062 o ring and bolt handle 392LE009, the handle is $ 5.56 and the o ring is $1.15
The stock bolt pushes the pellet about half way past the transfer port, this one pushes it past and that helps performance a bit

RAKonTour · « **Reply #19 on:** March 14, 2014, 03:54:59 PM »

Ed,

Thanks for the follow-up. I actually had all those parts numbers on my list except I had the knob for the bolt as part # AS2250-009, which is the same knob as on my 2300KT. Is there an advantage to the other knob - 392LE009? On which gun's parts diagram will I find that part? I'd like to check it out.
