Things I liked: The sight is the main reason to upgrade, I purchased it with the gun so it was already install when I got it, what else can I say steel or plastic with a sight that's not dove tailed and isn't easy to adjust, you choose.
Things I would have changed: The sight wouldn't adjust down enough to get centered at 25 to 30 feet the distance I am shooting indoors with 5 pumps. It shoots about 1-1/2" high at the lowest setting. (fixed see my review on the gun)
What others should know: When I first sighted it in I noticed that the bolt handle was angled to the rear. I have the 22 version as well so I thought the angle may have been changed on newer models. On closer inspection the bolt handle was cross threaded into the bolt. I thought I might have to send it back but it turned out that I was able to dress the threads and correctly install the handle.
Things I liked: I've always liked my Crosman 177 pistol. I use it for plinking and getting rid of critters who like our garden as much as we do. Wasn't sure if the steel breech would make much difference and not sure it does. The new sight that comes with the kit is fantastic. Much better sight picture. Fully adjustable!
Things I would have changed: Instructions aren't the best. I got a better set from Crosman. It tells you to loosen the barrel screw to lift the barrel up and out. My model doesn't have a barrel screw.
What others should know: Kind of tricky re-installing the valve (don't remember the part name) but when it goes in it works great. I love the gun!
Things I liked: Great upgrade for a 1377, allows for a good rear sight instead of the cheap factory one. Had a problem with the first order, the package had been opened and there was nothing inside. Pyramid Air sent the order again. Awesome customer service!
Things I would have changed: I had to tap the bolt for the handle installation so some QC is in order, otherwise simple.
What others should know: My 1377 was from the early 1980's and upgrade works great.
