Things I liked: The individual components are well made and the technique, instructions and tools for changing out the receiver were fine.

Things I would have changed: The interface of the LPA sight and the receiver was not well thought out and needs to be redesigned, Three screws are used tighten down and adjust the sight on the receiver. However, in doing so, you wind up lifting base of the sight off the receiver platform. The only interface is now the bottom edges of the sight dovetail with the top edges of the receiver dovetail. I had no confidence in that arrangement what so ever. I finally just glued the sight to the receive. Of course the end result of that is I have no elevation adjustment capability.

What others should know: Don't buy it if you're really looking for a fully adjustable sight.

Things I liked: Quality steel construction, look and function of the LPA rear sight on the steel breech 1377. The LPA is a huge improvement over the stock sight.The look, feel and weight of the steel breech on the 1377 make it rock solid with the option of optical sights. It now feels and looks more like a firearm. The steel breech helps reduce the slight barrel movement with the plastic breech. I would have given 5 stars overall except for need to alter front sight.

Things I would have changed: The fit into the dovetail should be tighter and the sight should sit lower in the slot. The stock front sight on both of my 1377s was to low and had to be raised to allow for adjustment low enough to get on target. Nothing to change about the breech.

What others should know: If you run out of downward elevation adjustment, your best bet is to raise the top of front sight. It's easy to do, costs little or nothing and takes just little time and creativity.Read my comment on this review page if you want to see how I fixed mine.I know you shouldn't have to but if you like the sight and breech combo it's worth it.

Things I liked: This increased the velocity of my 1377 with H&N Trophy copper-coated 8.80 grain pellets. The stock breech would barely sink the pellet into my plywood backstop or sometimes bounce off at 20 yards. With this installed it buries the pellet in the plywood anywhere from up to the middle or base of the skirt.

Things I would have changed: I'm not so sure about the white dots on the sights. I'm thinking about blacking them out to provide better contrast. It'd be nice if they had a precision factory peep site made to these same dimensions, and not bulky like the Williams one. I wish there was a quality precision front sight besides the junky plastic stock one.
