I was wondering if anyone had any links to 80% ar15 lower receivers? I was able to find DSA lower forged receivers that are 0% but cannot seem to find anything that is 80%. I remember seeing them last year at the tannery shop. I have access to a drill press but not a mill. This is why I am looking for 80%. Any help would be much appreciated.

I got mine at https://www.vbd.com/noc/shop/products_detail.asp?CategoryID=29&ProductID=272.

Here's the finished product. It works perfectly and totally stealth except for a hidden serial number.

nice work on the lower.

Did it come with a SN or did you do it yourself? And if you don't mind me asking...Why?

I saw a post on the Roderus site that claimed ATFucks were changing their rules to classify AR lowers that have the trigger well machined as firearms. Be careful... the nazis use this sort of ruling to shoot first and ask questions later.

The finish is Norrell's Moly Resin in Flat Black. The stuff is really durable and solvent resistant.

I spotfaced the takedown pin hole with a 4-flute end mill 0.437" dia.

The cutter I used for the front trigger guard pin was 0.250" dia with a short vertical cut.

The 80% lowers are not considered to be a firearm by the BATFE, therefore they are not serialized. I added a very unique serial number so that I could readily identify the rifle should it be stolen or whatever. As the "finisher" of the lower, I was not legally required to serialize it since I am not regarded as a manufacturer by BATFE.

They want more for an incomplete receiver than I paid for a complete RRA after tax.

You are absolutely correct! People that finish 80% lowers do so for a variety of reasons which to them are priceless. To each his own!!

Well the actual reason I did choose to build an 80% AR is due to the paper trail. I just don't like the idea of the government knowing I have an assault rifle. Call me paranoid but things can change over time. I wouldn' call myself a crazy person but I would feel more comfortable having an AR if it wasn't registered.

I now live in the State of Tennessee and have since learned firearms are not registered. Instead background checks are done to check if I can purchase a firearm. Due to this I have decided to purchase an Anvil Arms lower receiver. I will likely purchase a few 0% forged receiver as I have a family member who is an excellent machinist.

Thank you for posting a picture. By the way your rifle looks great. i hope mine will look as nice as yours.

I saw this too. It also stated there could not be any drilling or even dimpling of the pivot pin holes. The ATF stated they considered dimples to be the same as fully drilled holes.


I would not buy any unfinished receiver unless it came with a certificate stating it was BATF approved as of a few days ago.


Some folks selling/buying receivers that were legit previously, are probably now unknowingly violating federal law, and the ATF will throw them in jail.

they are not violating federal law until convicted, they are just violating the decree of the BATF. you see, these days, they just say something and the threat of arrest is enough to stop people from doing things. Which I think is absolutely wrong.

I make over $21/hr running a CNC milling machine at work. I have all the CAD files, solid models, blueprints, and CAM software I need to finish one(or machine one from a billet or raw forging for that matter). It's simply not logical to spend two or three hours on setup and machining, plus the time programming and building fixtures while paying more....

I'll pay a fellow machinist until I get bored, desperate, or paranoid.

That is just a forged blank, not an 80% finished receiver. The internal milling has not been done.

not to hi jack the thread but since you are making it yourself and there is no serial number, can you legally make it an SBR?

It appears that a 80% lower receivers are supposed to be sent to the ATF for a determination and that the above letter was in response to one particular receiver being submitted for a determination –– apparently, it determined that it didn't qualify as an "80% complete receiver".

Absolutely not, unless you do the BATFE paperwork and pay the $200 fee for the tax stamp.

2-3 hours eh? I have been working on 8 raw forgings. Doing all the programming, fixtures, setups, CAD work, EDMing, and actual cutting time, I have over 50 hours in 8 0% raw forgings. My time is free, so I really only have the cost of the forgings, and a couple of tools in them. It's been a fun project, but I'll probably just buy lowers next time.

As to the OP, just buy finished lowers, unless you plan on doing one from a 0% forging. The cost of a 80% "forging" + finishing is just plain silly.
What is ominous is the ease with which some people go from saying that they don't like something to saying that the government should forbid it. When you go down that road, don't expect freedom to survive very long. – Thomas Sowell

Seems the 80% fad has passed. I remember when they first came out, folks were all over them.

I'm really curious just how many of those 80% lowers ever got finished. I suspect the project proved more difficult than many realized.

Actually, I found the last 20% to be pretty easy. I used another completed lower as my pattern and drill guide and did the whole thing on a good drill press with a 2-axis slide vise. A friend and I shared the cost of the extension tube hole reamer and tap. Already had all the other end mills and drills. It took about 6 hours to complete the machine work including setup and machine time. Blasting and Moly Resin took another hour. It was fun and rewarding.
