Also for hobbiest who likes to mill his own metalware; hand made pride... add to that, you could make changes to the normal design, for example, better/ different trigger guard, better/different grip tang and pistol grip design; better/different forward magazine well wall with finger groves; and finally my dream; better buffer tube connection/ butt stock connection zone... well you get the idea; you can do any thing you want with it... paint it your way/ different company's parts/ trigger job for accuracy, etc. Anything for the DIY/ home made gunsmith. All okay without the liberal press one day publishing your name and address because they got into the FFL/ back ground check files (Fm 4473)(or CCW files). All legal and legit... Regards

Off the grid

Search on here for 80%; and then too, go to Armslist.com and search for 80% receiver... do your home work and judge your skills accordingly. I just saw what I would call 50% receiver ( also nicknamed the "paperweight") as it does not have any of the holes milled out, drilled out, to include threading any/all areas which need threads... to include the buffer tube area. Ouch, that's past my skills... I can do all the vertical drilling I need; but don't like threading screw holes to standard; nor many of the different vector drillings needed.

Nor do I do any fancy finishes... just duracoat paintings... Good luck with your hobby/ search!
