Crosman .177 Caliber Steel Breech Kit Reviews

Santa Rosa, CA

I would recommend this item to a friend.

Awesome upgrade
August 30, 2017
This breech was a snap to install, and I love the weight and balance it brings. The long dovetailed top let me install 4-7x 32 optics's to shoot dime sized groups with cheepo pellets.
Perpendicular dovetail at rear for Williams peep sight
Breech plug protrudes too far to allow reuse of factory sight (no great loss.)

Great improvement over plastic
August 10, 2017
Took no time at all to install, really easy since the instructions are a little poor. As well as loading pellets much easier for my chubby fingers, it hold the pistol scope SOLID with no wobble and with the addition of a set of target sights (iron sights only matches) everything is working great.
Just what I wanted and at a price lower than I expected. As a old shooter, much easier to handle than the OEM.

upgrade is awesome

this add on part makes the "toy" feel more like a "gun", added a laser adaptor and added a screen dot as well.

Excellent Upgrade
June 24, 2016
This steel breech is easy to install and of excellent quality. The only down side is that the stock rear sight no longer fits on this breech but I knew that when buying it and have a scope that I will be using in place of the open sights.
11mm Dovetail allows for scope mounting that original breech does not.
Not truly a con but you can't use the stock rear sight with this breech unless you do some modifications to the sight.

Better than stock enhancement
September 22, 2015
Installation of the steel breech kit was fairly quick. Gives your pistol a nice custom upgrade
Smoother breech action. Mounting rail allows for a variety of optics or sights to be used.
