Hey guys I am fairly sure that I know the answer, but wanted to run it past you guys to make sure that I have my ideas going the correct way...

I am looking at building a compact carbine rifle that I can toss in a backpack and take with me just about anywhere. I was looking at either the 13xx or the 22xx ( both in the .22 version ). I already have a 1377 as well as a few spare parts for that as well as the 22xx. I would like to have a .22 as I have a ton of pellets and nothing to shoot them with. In the box of parts that I have I found a steel long breech and was planning on using this for the build. Being as I will have to find a barrel for the build I am under the impression that the breech is the same for both the 22 and the 177 pistols....correct?

And if so what is a good place to find barrels in stock? Would love to find a LW barrel, or something close to that for the accuracy....but not looking to spend a load on it.

Any help or ideas would be greatly apperciated!

Thanks guys.

Steel breech's can have the small screw (4-48) in the aft (under the bolt) or forward position. The aft screw position will not work on the 13xx guns, as they do not have a hole in the air tube there. A .177 or .22 bolt will fit in either breech.
You should check out the Crosman custom shop, you can build your own 2400 carbine with any length barrel up to 18" in .177 or .22 cal.

Yup, the first place I would look for a new barrel was the Crosman custom shop!

Thanks for the links guys.

As much as I would like the custom shop, would love to build it all myself. That and trying to find the parts and make something that I have in my basement already.

And is there anyone making an all in one valve and drop down for the 22xx rifles?

Sweet. I was looking for just such a list. Thanks, Dave. By the way, I see you have a 2240 in both 22 and 177. I am planning to either build another 2240 in 177 or convert the one I have to 177. Did you notice any difference in velocity and CO2 usage between the two calibers? Is it worth doing?

daveb50 · « **Reply #7 on:** May 14, 2013, 10:11:49 PM »

I thought I would try a 10.25" .177 barrel I had on this 2240. It didn't seem to make a difference in Co2 usage, and I don't have a chrony, but it seems to have plenty of punch. It is very accurate with RWS R-10 pellets at 5 & 10 meters. I've ordered a 24" .177 barrel that I'm going to cut down to 12" or 14" to try on it. I have done so many mods on this now that I had enough parts to build a stock 2240, that's why I have two now.

I just bought a .177 24'' Disco barrel for my 1377. By cutting it at 17'', I will have 7'' take off and will modify that to fit as a replacement barrel on the 2240 so I can shoot .177 from it!!

I don't have a chrony either. Would be interesting to see what the 177 steps out at compared to the 22. I was hoping to stretch CO2 usage out a bit by changing out calibers.

From all that I have read, you WILL achieve that goal!

I'm at a loss as to thinking changing to a smaller pellet will increase co2 output when you are still using the same valve volume? I would be interested to how this works.

Good point. I'm still learning this stuff. I was thinking that going with a smaller pellet would decrease the amount of CO2 needed to propel the pellet and thus getting more shots per cartridge. But I can see that is not the case if nothing is done to the valve. Actually it would seem that CO2 is being wasted, or is it resulting in increased velocity? Am I way off here?

bgmcgee · « **Reply #14 on:** May 16, 2013, 10:46:51 PM »

I have both a 2300kt which is .177 and the 2240 they both run the same valves and I get a couple of more shots with the .177 but I only think that's because the pellets are half as heavy if that makes sense to you.

Makes sense. So I am probably going to revert my 2217 to a 2240. It was shooting very well as I originally had it configured. Should have listened to the old adage 'If it ain't broke, don't fix it!'

I'm posting this so I can find these part nos. next month when we get back to the 'home ranch'.

Oldgringo · « **Reply #17 on:** October 12, 2013, 08:49:58 PM »

Well, we're back at the 'home ranch'. So, there's not a 12-14.5" Crosman .177 barrel for a 1377 mod? $:-\$

daveb50 · « **Reply #18 on:** October 13, 2013, 06:16:29 PM »

You can get one any length from a vendor, such as Mountain Air or Mellon -(has backlogs that can make for a long wait).
Crosman only makes these sizes.
.177 (4.5mm)
Length Original Gun Crosman P/N
7.5” 2240 Only 1740-002
10.25” 1377 1377-025
10.1” 2300s LW Match 2300-102

Gertrude · « **Reply #19 on:** October 13, 2013, 06:50:14 PM »

Greg,

You can get one of the 24" and cut it to any desired length, crown it, with a hacksaw, hand file, hand drill/ slotted screw (for crowning), blueing pen.
Easy stuff.

Daveb50,

what is the difference between the two 18" .22 barrels ?

18" 2400 2400-102
18 " 2250XE 2400-006
