Interesting, I do know this, at 80percent arms they have a Glock Kit, but you have to Purchase the Rails SEPARATELY, so you have to make 2 purchases, one for the kit and one for the railings and jigs. They will NOT Ship them Together either. Sounds like this is where Polymer80 screwed up, by sending everything in one box as a complete kit. I would bet this only applies to Handguns also
The miracle of the crass.
