  • Crosman .177-cal. steel breech kit
  • Fits Crosman airgun models 1377,* 1740, 1760 and PC77
  • Will accept the Crosman LPA MIM rear sight

The original rear sight that comes with any of these airgun models will no longer fit on the steel breech. If you want a rear sight, the Crosman LPA MIM rear sight is made for this kit (CR-2300-010[PY-A-4385]).

*This breech does not fit older model 1377 air pistols with a sliding breech cover.

Things I liked: Easy to install and the directions are included are good.

Things I would have changed: The bolt handle likes to loosen up - this has happened to both of the 1377s I modified. Its easy to fix with some thread lock.

What others should know: This is a quality product that makes scope mounting on the 13xx much more solid and reliable.

Things I liked: It makes the 1377 into a very solid feeling, and accurate weapon. Highly recommended

What others should know: If you like the weapon before the conversion, you will like it a lot more AFTER the conversion
