Nice Product
This is a great value and a great product. The combination of the slide, barrel, metal sights (not Glock plastic) AND the RMR cut is outstanding! This is the first time I've "built" a gun and used a 26X frame to put this on. My only disappointment was in the "lower parts kit" not including a locking block which is required to build a Glock knockoff. I was further disappointed by the rather cold response, "locking blocks are never included in any of our kits." I don't mind buying it, and did, but it took extra time to work through this. Even a reply that said the same thing along with, hey, we have those in stock if you'd like to order one....or something other than no.

Lf26 slide
Fairly impressed for the price. Ordered on a Sat got it Tuesday. Good fit. Rmr cut for holosun so no adapter needed.

Great set
Lovely, well fitted pieces. If it fires as well as it looks, this is a big value for the price.

G26
I received my item on the day it said I was supposed to get it I opened it up I was very satisfied I inspected the merchandise it was very nicely made I started to put it together everything went together very nicely I'm very happy with my item and I will be ordering again very soon I thank you very much I was going to buy another one but there's no longer a sale on that item I should have ordered two of them I'm so happy with it but made a mistake maybe next time when they're on sale like that and I'll order two of them at the same time
