Complete a 80% lower with a jig and common home tools!

The horse is out the barn.  Knowledge is the most powerful thing that any person has and AR-15 know how is spreading.

Sometimes you do things because they're necessary, and sometimes you do things just because you can.  I don't know where this falls but its definitely something everyone should try.

Sidenote.  No registration necessary with a 80% lower.  We're heading into the last year of the Obama Administration with the threat of Hillary taking over....this golden age of AR-15's won't last forever (Republicans screwed themselves with the backdoor budget deal and the complaints about the debate is just to pacify the base).
