Steel Breech Kit is rated 4.6 out of 5 by 18.
Rated 5 out of 5 by from Makes a great gun even better! I bought this to put on my 1377 to be able to mount a scope. Install was easy and I enjoyed doing it. Crosman seems to have best price in the Breech. It also looks much better and gives the 1377 better balance in my opinion. Money well spent.

Rated 4 out of 5 by from Steel Breech kit Original was ordered on 7/1/2017. By 7/6/2017 I had not received confirmation of order or any other communication. I sent an email canceling the order and placed another order which I received instant confirmation and the order was received about five days later. I installed the breech and was very pleased with it. On 7/20/2017 I received the original order with paperwork saying it had been canceled. Email to Crosman has gone unanswered. The order is being returned.

Rated 5 out of 5 by from Great ugrade Received the steel breech and have it installed - it's a great upgrade ! The only small problem was the instructions that were sent - evidently it's a copy of a copy of a copy - not only was it very light and hardly legible but the instructions were very very small print ! I found several links on utube that made the install very easy ! That being said - I'm extremely happy - this was an upgrade for my 1377 - I'll be ordering another one for my 2240 !

Rated 5 out of 5 by from Great upgrade! I ordered this steel breech and LPA rear sight for my 1377 from Crosman. I received it in good condition about 5 working days after I ordered it which I thought was timely delivery. It installed fast and easy and improves the look and function of the gun. I had no problem with the plastic breech but wanted the upgrade with option of optics. Iron sights work for me with the pistol configuration 1377 but with the shoulder stock the rear sight too close and blurry for my eyes. I like the LPA sight but the fit in the slot is very loose before using set screws to tighten it up. Some minor tinkering will easily correct this as well as shooting a tad high with elevation adjustment all the way down. I would recommend this quality steel breech to anyone considering this upgrade. It makes an already nice gun much better. I will be ordering another steel breech for one of my other 1377s as soon as they come back in stock.

Rated 4 out of 5 by from Solid construction Works great with crosman target finder scope, I only wish crosman would make a rear iron sight to fit this breech. Sometimes I like to shoot open sights, and have to reinstall the original plastic breech. It would be a 5 star for sure if they made this possible. I know there,are after market sights I can use, but are extremely expensive.

Rated 5 out of 5 by from Nice Kit - Good Upgrade This kit is awesome. It gives my 1377 a more substantial feel and I really like that pistol. I mounted a red dot sight & it is amazingly accurate at 50-60 feet. My only niggle is that the bolt fell off often, but it wasn't anything a little Locktite couldn't fix. I certainly would have paid the extra $ to have it installed stock.

Rated 5 out of 5 by from Heavy Durable Stands the test of time Accurate I brought this steel breech for my 1377 All American Air Pistol a couple of weeks ago . It enhances the apperance and accuracy. I look at all my air guns as life long so any thing I can do to perserve my investment and make it better I do. One unique thing about this air gun is modifications are as far as your imagination can go.

Rated 5 out of 5 by from Great modification part I bought this simply to land a scope on my 1377. I have the newer model but had one of the original 1980's version when I was a kid. It was lost while I was in college. Anyway, I am teaching my youngest daughter gun safety and how to shoot. Not only is this a solid platform for a scope, it seems to have lived up to its reputation for a small increase in power as well. Please note that when you install it, make sure it is seated correctly on the air port. Youtube it. My first attempt at installing it was a failure. It actually looked like it was seated correctly but when I fired the gun, I could feel air around my hand. I had oiled the breach as well so I did see a pattern of oil blowing out where the two pieces mated. I took it apart and reset it and it performs nicely. It is well built and fits the gun perfectly. There are several videos to assist with install on Youtube. Fit and finish is really nice. Well machined and good tolerances. I would recommend this to anyone looking to mod their 1377.
