Review for model:

The first screw (the one in the center of the breech) is hard to turn with the provided key, but then it goes smoothly. A bit of oil after installation, and it works wonderfully smoothly. It's much heavier than the original, so the center of gravity has shifted nicely to the grip line.

Review for model:

After adding a stock to the Crosman 1377, a chain reaction occurred. The peep sight only allows for fairly accurate direction shooting, but the pistol's (subcarbine's) potential for precise shooting is incredible. The next step is a metal breech. Installation is extremely easy, there is plenty of information and videos online on how to do it. Just a few minutes and the conversion is done. An essential element for mounting optics. Flawlessly made, Crosman gains character.

Very good product. I replaced it without any major problems, using the instructional video as a guide. After mounting and calibrating the laser sight, it repeatedly hits a five-zloty coin at 25 meters.

The breech does its job perfectly, everything is stable – you can mount a laser, a scope, and an adjustable metal rear sight.

Revelation. Solid workmanship. I recommend it.

Excelent product. It was installed in a very short time and the air gun (1377) works perfectly. I strongly recommend this specialized site. Thank you Militaria.

If you want to mount a scope securely, you must have this breech. Forget about adding a separate bolt for the barrel. I recommend it.

The breech allows you to attach additional elements; it is metal and longer than the factory plastic one. This definitely improves all the features of the weapon.

This breech is a great idea, too bad it's not factory-installed. You can mount a scope solidly, which is useful on a Crosman with its energy and stock.

The breech met my expectations, the scope holds firmly to the air rifle.

The breech is a bit expensive, but if you want to use a scope, it's worth it. The scope sits securely, and the airgun gets that something extra.

A bit expensive, but worth it. The scope sits securely on the Crosman, I recommend it.

A must-buy for the Crosman 1377.

Very good product, a necessity for the Crosman instead of the plastic one.

It's worth replacing, you can do without buying an additional bolt for the barrel.
