22 Caliber Steel Breech Kit
July 2, 2019
This Breech Kit is easy to assemble. The fit is excellent & machine to high tolerances!
ProsCannot be beat as a replacement assembly!
ConsSteel must be maintained. Steel does rust where brass does not. They do not oxidize at the same rate & both requires oil!
Best UsesThe best replacement kit one can buy.

Required for the mounting of optical sights
February 27, 2019
The Crosman steel breech kit is necessary for mounting a scope or red dot sight, and/or a longer barrel, to the 13XX and 2240 air and CO2 guns. I own several of these guns and have installed steel breech kits on all of them. The kits are very well designed and manufactured and will enhance the function and appearance of the gun. They are easily installed and come with written instructions. The standard plastic breech will work if you plan to use the standard rear sight that comes with the guns. There are mounts that clamp onto the barrel for mounting standard dovetail scope rings but I have found them to be difficult to attach firmly which affects accuracy. The steel breech kit enables you to get the most from these guns, in my opinion.
ProsVery well designed and manufactured from solid steel. Easy to install. Gives you many options for attaching optical sights. Brings out the accuracy these guns are capable of producing. Also allows you to easily change barrels.
Best UsesFor Improving functionality and accuracy of the Crosman 13XX and 2240 guns.

Great Upgrade
July 10, 2018
Modifying a gun is not something I have ever done - somewhat daunting proposition. However - despite unclear description of one miniscule invisible (until disassembled) part. I achieved the changeover with minimal frustration. If I can do it anyone can.
ProsRelatively easy to install.
ConsInstructions could be clearer.
Best Usesupgrade from a plastic breach to a metal one with dovetails for installing sighting options.

LPA rear site fits to loose.
June 23, 2018
I received the steel breech kit and installed it on one of my 2240's, which by the way was pretty simple. I like the little bit of extra weight it added to the gun also. However I also ordered and received a LPA rear site to go along with this kit, as the factory rear site won't work with the steel breech kit. Sliding the new rear site in the dovetail of the breech was very easy, really to easy and after tightening the two small set screws I noticed a large gap between the bottom of the rear site and the breech. I wonder I any one else has noticed this?. I think if I try to tighten the set screws any tighter that the site will pop right out of the dovetail in the breech, not much of the breech dovetail is in contact with the rear site. I don't know for sure if the dovetail on the breech was cut a little to large or if the LPA site that I received is possibly the wrong one, packaging for the LPA rear site shows a part number of CR-2300-010. I would like to find out what size dovetail is supposed to be machined in the steel breech, I know mistakes happen. I think I can possibly shim the rear site to fit the dovetail on the breech but buying parts that are made to go together shouldn't require shimming in my opinion. I really didn't buy the steel breech kit to add a scope to my 2240, I will be carrying it as a backup while ridding various rodents for local feedlots, while also using my air rifles, and the use of open sites on an air pistol at close range would be ideal as it ill be carried in a holster. I think even though tight, that the rear site might just pop straight out of the steel breech dovetail while carrying it in a holster and it will be lost.
ProsAdds a little extra weight to gun which I like.
ConsLPA rear site is why to loose in breech dovetail.
Makes a fun gun feel less like a toy
June 21, 2018
I ordered this part for my 1377 when changing to a .22 barrel. It's a really nice improvement over the plastic piece they come with and adds some, much needed support to the barrel. The plastic breech only supports about 1/2" of the barrel, the steel breech adds a couple inches to that and secures the barrel with a setscrew. The MIM rear sight seemed expensive at the time, so for now I'm trying another sight from someone else that may be a more affordable alternative but may also require much more tinkering to be accurate.
ProsLess toylike feel, more solid, hopefully more accurate.
ConsNone, it should be a standard part. But they would sell a lot less guns when the price goes up.
Best UsesIt's a good upgrade for anyone who wants a more solid and better shooting gun than what Crosman sells.

Should be shipped in a box, not a bag
February 22, 2018
Works as it should. It's a must for building a solid gun.
Merchant Response:We sincerely apologize for this and totally agree with you. We have notified the Shipping Manger about this and these kits will be shipped properly in a box. Thank you for bringing this to our attention and thank you for your business!
ProsDoes the job.
ConsIt's shipped in a mailing bag instead of a box! Kind of hard to believe, really. There's a scratch and ding factor for the bolt and the small hardware and tools because they get crunched together and pressed against the breech during shipping.

Easy, excellent upgrade.
March 1, 2017
Much more stable barrel mounting that adds just enough weight over the trigger. Easy to pick up a target and stabilize the sights with that weight. Nicely machined WITHOUT razor-blade edges all over.
This upgrade is a bit deceptive as you must also upgrade the rear sight(yes the sight IS nicer than stock). Not a big deal if the sight wasn't so expensive (more than the breech).

In deciding what should my first modification should be I did a lot of research, and also thinking ahead to what direction I wanted to take that would make future mods possible. So, since this is my first pellet pistol and never took it apart before I thought I could do this. It was a lot easier than I imagined. There are instructions and all sorts of videos on the TUBE to help. Don't let it scare you, this Steel Breach Kit you need and will make all the rest of your mods possible.
ProsIt opened up all kinds of 2240 modifications; has open sight slot, scope rail, can change barrels and more.

Best way to start
October 18, 2016
The Crosman 2240 pistol is a great gun with many modifications available. The first mod you should consider is this metal breech. It allows dovetail mounts to bolt right on to hold your red dot or pistol scope. That addition will make your gun even more accurate than it is out of the box with open sights. Another benefit of this breech is that it's durable. You won't wear this one out. Even though it's half again the price of the pistol, it's well worth the investment. Polish the trigger and you've got a great target pistol for under $100.
ProsQuality construction, easy to install, good value.

If you have a 1322 this is a necessity.
October 18, 2016
If you intend on scoping your 1322 combo this will enable rifle like accuracy out to 20-25 yds and a stable mount that will allow no movement of the scope.
ProsEasy to install.
ConsWatch out when using the small allen wrench on the breech screw.

Works fine, as advertised, fit gun good
ProsIs as advertised, fit good, easy to install, just take your time and make sure everything is lined up right. Alot more rigid than the factory breach and allows for secure way to mount optics And better secure the barrell
ConsDoes not allow use of factory rear sight, so if want that option (open sights) be sure to order some after market rear sights
