Any difference in 80 lower on quality I live in Maryland my buddy wants to get one thanks

Well, it's legal to posess, but milling it out and making a rifle would not be advisable after 10/01/2013.

Since there is no identifying information engraved/stamped on the receiver, who knows when it was made?

and, there's the rub......

TacticalMachining.com.  I also recommend their jig sets.  Very good quality components.

CNCGuns.com is a good resource for plans/dimensions if "your buddy," who presumably lives in another state, wants to finish them.


If "your buddy" doesn't have access to a machine mill and doesn't care to try his luck with an aluminum 80% with a Dremel (it can be done, but requires mucho patience), I'll also recommend the Polymer 80 products.

They're sold directly at polymer80.com, or through Ares Armor (which is a good company, good people, involved in their own legal battle and could deffinitely use your/our support).

Finishing those is much easier, but the polymer lower is somewhat weaker than aluminum.  But, for half the price, assuming "your buddy" just wants a light use rifle, it may be worth considering.

Finishing info can be found here (no embed; the video description contains even more useful info):

Paper trail. If ordered online, Id assume you'd use a credit card. Therefore, it doesn't matter when it was made because you would have taken possession of it after Oct. 1, 2013 I can imagine that if you'd went out of state and bought one with cash, there would not be any evidence to prove you've committed a crime. That's still treading on thin ice seeing as a gun with no serial numbers in a place like Maryland is a magnet for questions from authority who give a damn. But hey, heroin and meth is illegal too and there's still plenty of people buying, using, and not getting caught with that.
