"Beyond legos for gun nerds comes this soon-to-be-AR15-lower (aka package of raw metal) that can be transformed with skill and welding. Designed and machined by The Flat Spot, this assortment of metal is what I have dubbed a 25% lower receiver. Whereas 80% lower kits only require a drill press and finishing, this flat set requires welding and tapping of the receiver extension hole.
Practical in the days where complete lowers can be had for $30? Probably not. However this kit looks like a lot of fun for a dedicated builder. Sure, it will end up heavy, less polished and less than milspec, but you were the one who actually brought it to life. And government, serial numbers, NICS checks, Molon Labe, yada-yada-yada stuff too."
