80% lower

[Mattech]

Yup, just need a jig. I've done a couple my self. I had a stripper lower with me just to use as reference.

I was considering striping my current lower down to us as a reference also.

That'll work.

This particular lower can be used with a full auto set-up. See Description:

"These 80% AR-15 Lower receivers start as 7075-T6 forgings from the lead forge in the US and are fully machined to mil-spec tolerances. The operations left to be completed are as follows/ fire control group, trigger pin, hammer pin, trigger slot and the safety selector hole. These are our Gen2 80s and have the rear lug area cut out. This is a not an FFL item. This is not a complete receiver and still requires machining to be done. We have a copy of our ATF determination letter and our determination update stating that it is not a firearm"

80% lowers are more about thumbing the govt than they are cost.

Yep. Plus it's just a fun project to do.

I also like having a lower receiver that has no markings on it. I just really like the clean look.

Try 80percentarms.com

You can use their jig with a router. Much easier and cheaper in the long run.
