I'm thinking about building my first AR15,which will also be my first AR15 ever. I'm thinking about getting a XM177 kit cause I really like how those look and I don't need or want any rails because I don't use optics or front grips,I prefer iron sights and using my support hand on the magwell,so I'll be getting the kit with the A2 upper.I'm going for the Vietnam era XM177 look so I'll also be using metal 20 round mags. This is the kit I'm thinking about: https://www.model1sales.com/index.cfm?fuseaction=category.display&category_id=226 Has anyone else built one of these?(if so how did it come out?) Does anyone else know of some good kits use A2 uppers and has no rails as an option?
