I believe those 5D jigs can work on 80% 9mm AR9 lowers. I know little of the adapters used in these kits for working with one magazine or another. You need to go to their site and see what is what.I agree but this is a special build that uses M&P 9mm mags.
The biggest purchase if you do not have it is the router. You must have a router that is compatible with their tooling kits. If you very knowledgeable about tooling you likely could obtain drill bits and milling tools on your own. The smart is probably to buy it all from them. I have not made one yet, but I have looked into it.For those who have done the research.......Does the 5D jig require "special" tooling that can only be purchased through them? Some jigs I'd seen require milling bits with non-standard or non-commereially available shaft/cutter dimensions. I do like that 5D Tactical has a jig that can mock up any lower for multi caliber applications, but it all comes at a very steep price.
The jigs are designed to remove metal that correspond to the geometry of the jig. You order what is needed according to the router that you have.OR, perhaps someone is looking to build something unique. Something not on the market. Such as an AR lower that uses M&P magazines. I already have a drill press an routers. And I'm completely fine with law abiding citizens manufacturing their own guns. And just because it's cheaper to purchase a serialized receiver, doesn't make it any less obtrusive to our rights as citizens. Sometimes principal has priority over price. Just sayin'

If you are doing an 80% you will not being saving money over buying a 100% Andersen receiver and the only obvious motivation is a desire to do it yourself or to have what they are calling ghost guns.
If you can swing the $ get a small CNC that can cut them out of a billet.
There used to be a specific CNC that would only cut lowers out of billets. May still be around.
As already stated there are two obvious goals here that some use for justification.Yes, There have been a few. I believe the most well known is the "Ghost Gunner" CNC machine marketed by Cody Wilson. Unless a private citizen is making countless lowers for himself, I can't justify the added expense of a $300+ jig plus machine tools if someone is only completing a couple lowers.
I have completed lowers both a drill press and/or handheld router from Billet 7075-T6 aircraft grade aluminum in a matter of 3 or 4 hours. And this includes the setup, measurements, etc.
Maybe some people will spend hundreds or thousands of dollars and get a couple finished lowers that would cost less than $75 each completed and brand new.
It may sound like I'm playing Devil's Advocate. I have completed close to 40 lowers and at the same time I'm perplexed as to how people can justify spending several "C-notes" when it's not necessary.
