I don't waste my money on other types of mounts anymore I wish they would make the rear sight grove smaller to fit the 22 rifle style buckhorn sighys

sturdy well made machining is excellent finish matches most pellet gun finishes (80)% anyway.

bolt handle fit a bit tight but workable (tight in the downward position.) needs 2 barrel grub screws to keep barrel from tipping up when installed like the baker air guns BIG BOY model 20 seconds with a verry small file took care of that

Suggest to install a small o-ring on the upper part of the transfer port to minimize any air lost.

Great upgrade product. Upgraded a Crosman 2260 air rifle, prior the change it shot about 20 shots at an average of 484fps with Crosman Premier Pointed 14.3g pellets. After the upgrade I got 30 shoots at an average of 539fps with the same pellets.

No derrogatory remarks, is a great product.

I bought this kit to replace the flimsy 2-piece plastic breech that comes standard on the Crosman 2240 pistol. It provides a stronger clamping force onto the barrel, thus reducing, if not entirely eliminating, any barrel movement associated with the short plastic breech. This is especially important since I opted to install a 14.6" barrel in lieu of the 7.5" barrel that came with the gun. This in turn improved the accuracy of the gun. The breech also provides a solid dovetail base for attaching optics. In my opinion, this is a much better and solid platform for attaching optics than the barrel clamp style mounts, further adding to the accuracy. BTW, the longer barrel, without any other modifications, boosted the velocity from an average of 411 fps to an average of 514 fps using JSB Diabolo Exact Jumbo 15.89 grain pellets. This test was conducted indoors under the exact same conditions using the exact same equipment and techniques. I shot two 3-shot strings with the same gun powered by the exact same CO2 powerlet. The two shot strings were made less than 5 minutes apart-the time it took to swap the 7.5" to 14.6" barrel.

Except for the breech screw and a flat head screw driver, this kit includes everything needed to upgrade the breech and bolt on a 2240 pistol. It Improves the accuracy of the gun and provides a better way for attaching optics on the 2240 than barrel clamp style mounts. Even if you opt for open sights, it provides a notch to attach a more usable rear sight than the rudimentary rear sight that comes standard on some crosman guns. The kit is entirely made of steel. It is less susceptible to damage and is easier to take off and re-install than the flimsy 2-piece plastic breech.

A little pricey considering even with the discount it cost me about 79% of what I paid for a new Crosman 2240. It does not include a breech screw, so you must use the one from the old breech. The original rear sight on the 2240 does not work with this breech. Therefore, if you opt to shoot with open sights, it will be necessary to find an alternative rear sight system like the Crosman LPA MIM rear sight.

This Breech Kit is easy to assemble. The fit is excellent & machine to high tolerances!

Cannot be beat as a replacement assembly!

Steel must be maintained. Steel does rust where brass does not. They do not oxidize at the same rate & both requires oil!

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.

Very 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.

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.

Relatively easy to install.

Instructions could be clearer.

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.

Adds a little extra weight to gun which I like.

LPA rear site is why to loose in breech dovetail.

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.

Less toylike feel, more solid, hopefully more accurate.

None, it should be a standard part. But they would sell a lot less guns when the price goes up.

By KFebruary 22, 2018

Works as it should. It's a must for building a solid gun.

Does the job.

It'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.

By JoshMarch 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).

Crosman 2240 Pellet Pistol steel breech kit The kt is a custom build that the customer wants supplied by crosman. My 22xx custom breech will fit but only if the KT gas tube has a front breech screw, not a hidden one under the probe. My right hand is useless to me, (Stroke) I want to get to that in target grips.
