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 Priority Upgrade! I found that I gained fps while also increasing consistency in groupings at various distances. I later added weaver rail adapters and a truglo 1x30 red dot scope. This made it even more fun. Good squirrel gun.
