This is a good point, and a great reason to get a mill as opposed to a jig (only). Mills are dang useful.

I would have to second this.

The only 'proper' way to do a real 80% lower is with a proper jig, router, and drill.

Jig: 280$ https://www.5dtactical.com/multiplatfor ... 5d-pmj.htm
Router: 165$ https://www.amazon.com/dp/B0049ZFUK2/re ... vDb0772FQJ
Milling Bits: 45$ (Can handle about 50-200 builds depending on material, so its more like a one off purchase)

80% Lower: 40 - 50$ https://www.5dtactical.com/ar-15-80-low ... -s/109.htm and https://www.80-lower.com/products/80-lo ... ed-1-pack/

Basically you will be paying an extra $490 - 500 dollars to save 10 bucks and a transfer fee off a completed lower, which can be found fairly easily right now for 60 - 200 bucks. If presidents change and things get scarce again, then it could make sense when all lowers are priced like gold blocks, but right now just buy normal lowers and save for future use. IMO

It is kinda cool for the novelty of it, though.
