a concept model i was showing the OP lol, i want to make some of my stuff but the tools required are expensive beyond what is responsible for me to spend as a married man.
Thanks for the reply. I'll probably get into building once the kit shortages let up. I was just at a couple of retail gun stores today, and the whole buying process they've set up pissed me off. They're regulating the browsing process like TSA theater at the airport.
Damn! Thats a sweet deal on that mill. Ive been searching for a few years now and haven't found anything nearly that inexpensive. did it work right away? or need some work?
I can't answer the downvote. My guess is it was an 80% lower with a jig. You can use a $50 harbor freight drill press to cut out the lower. Friend of mine did it. Worked really well. I have considered doing it myself for as easy as it was.
Example of one of many places to find the entire kit. A good kit also comes with the drill bits and such that you need to make it happen.
I'd personally avoid using a palm router on aluminum. The most important thing when machining metal is for everything involved to be as rigid as possible. Small routers tend to start at 16k rpm which is too high for aluminum without added cooling and if the cutter gums up and catches it can get ugly fast.
The router method works great for the polymer lowers, a friend just did an ar10 and ar15 and he said it was simple.
Maybe look into 3D printing and then making castings from the prints. The remaining fitment can usually be done with a hand file or Dremel tool if necessary. Biggest trial-and-error aspect will be shrinkage as cast metal cools, but it's a lot less with aluminum than what I normally work with (gold & silver).
i am versed in CAD i designed a full AR from the blueprints, all i would need is a cnc machine or like you said i could cast it but i would still want to 3d print it and acetone wash it to use as the reverse mould.
I think a solid 3D print in PLA (or better yet in wax filament) either sand cast or burned out and investment cast would be simplest. Seal the surface, print slightly oversized, and basically just sand down the casting to remove the layer lines. But that's all speculative; I was planning a cross-country move before all this WuFlu crap started, and most of my equipment is packed.
yeah anything is possible, i just need to find a pede who has a 3d printer and is into casting then lol, i have nothing, ive been stuck behind a computer on and off for 15 years, the rest of the time wasting with army, then nat guard....just havent yet had time yet to start my life, only have had 3 whole years of actually being able to concentrate on marriage and life lol no time to build and buy stuff i want is the point still way to busy to have hobbies, the donal is cool because all i have to do is go to my other screen while i work or am rendering somthing etc etc which is like 70% of the time
80% means that 80% of the work has been done. So someone else threaded where the butt stock connects for instance and drilled out the mag well. Usually some of the more complicated parts of the build are already done. 80% is also at the point where the ATF doesn't not treat it as a firearm. Any more work that is done to it requires a background check to purchase because at that point it's a "GUN".
Careful Pede... It looks like a self-milled lower, no problem except it doesn't have serial numbers. In order to have a short barrel and a rifle stock, you need a tax stamp. To get a tax stamp for a sbr you need serial numbers. Put a pistol brace on it and you're legal beagle... Just trying to help, not trying to crap in your cornflakes.
Because fuck the ATF and their unconstitutional laws. They can come and take it if my braces and barrel length don't fit their arbitrary poorly researched standards.
A lot of people have simply given up trying to comply in places like Kalifornia. Every 1-2 years they pass some other piece of shit law which requires me to alter my rifles AGAIN....
Whatever happened to the constitution specifically prohibiting both states and federal government from passing ex-post-facto laws?
If it is "green", the bullets can go all the way through a tree, a car, and a small truck. All three of which will instantly burst in to flames or explode.
I've seen it in movies, so it must be true.
There are lots of good ideas here for finish, I have been using Birchwood Casey “aluminum black” for touchups, it will also do large areas, if you follow directions and were to “soak” your entire lower in some sort of container
what type of cnc did you use?
You bought one of those 0% lowers, didn't you? This is dangerous to our democracy reeeeeeeeee
If I was going through the trouble of buying a "0% lower" I'd certainly be buying from a metal shop - not a firearms company.
do you have the CAD file?
https://i.ibb.co/XVLtBc4/image.png there is the spaceforce
What is that? Looks awesome!
a concept model i was showing the OP lol, i want to make some of my stuff but the tools required are expensive beyond what is responsible for me to spend as a married man.
Ah I see. Good stuff though. Might be a good time to find some fellow patriots in your area to split the bill for some of the fancier equipment.
You talking about the machines required or the tooling? Cause sometimes tooling is very expensive.
i was thinking i like the handmade look.....it adds another dimension idk...how to explain what i want to say
what part is outside the wheelhouse? The designing part?
holy based
Well done pede
I was just looking at those HF mills. $250 seems like an great price used. How's it working? Any problems?
Also...do you work from published drawings or do just do all the measuring and fitting yourself?
Thanks for the reply. I'll probably get into building once the kit shortages let up. I was just at a couple of retail gun stores today, and the whole buying process they've set up pissed me off. They're regulating the browsing process like TSA theater at the airport.
Why didn't you give her a girl's name? I mean comon, ya gotta do better.
Damn! Thats a sweet deal on that mill. Ive been searching for a few years now and haven't found anything nearly that inexpensive. did it work right away? or need some work?
Go to 80%arms.com
Buy their jig
Buy their router kit
Buy a router
You don’t need a cnc machine
It takes 45 minutes per lower
A router is just a portable mill
Your point?
Mine was that you don’t have to find an affordable ($250 mill) because a router which can be gotten for $100 will do just fine
why was this basic question downvoted?
I can't answer the downvote. My guess is it was an 80% lower with a jig. You can use a $50 harbor freight drill press to cut out the lower. Friend of mine did it. Worked really well. I have considered doing it myself for as easy as it was.

Funny, literally tens of thousands of people doing it exactly that way with zero issues.
I used a drill press for mine.

Upper is an M6A2 from LWRC, stock is magpul ACS. lightened hammer, polished sears. much better trigger pull than when it was stock.
yeah i want to make them from scratch to bring some of my inventions to life.....i like the way this cut that curve above the mag well opening

I kind of know what a lower receiver is but what does the 80% mean?

This jig is amazing
Down votes come from those of us on mobile accidentally down voting as we collapse threads haha :)
lol
Also known as "democrats."
Not sure, but just about any CNC mill can do aluminum with the right speeds and feeds setting.
Check out 5d tactical and multi platform pro jig.
looks like it could have been done on a Bridgeport if the operator knew what he was doing, but i would not be surprised if it was CNC.
he did it by hand
If it's time to bury them, then it's time to dig them up
Best comment ever
Best do this before... https://www.youtube.com/watch?v=MMdb0nhTE4A
I used DuraCoat FDE on mine about 8 years ago. Still holding up amazingly enough. https://imgur.com/FHUOTYr
Alumahyde from Brownells works amazing too and is easy to do.
Nah, 10 minutes with a sharpie should do.

Some Commie states, i.e. CA, you need to register it with the state and engrave your name and a serial number on it;
Sounds like you live in a free state (as do I) and you can do whatever you want as long as you are not a prohibited person
there was that one thing...
SHALL NOT BE INFRINGED
or something in regards to that... I don't remember the 'except' part of the 2A
Neither does the notorious ACB!
I don't follow unconstitutional laws.
Totally fucking false. AR-pistols aren’t illegal yet and ghost guns aren’t illegal yet
You’re right - sorry - my anger at the bullshit rules I took out on you
A lot of people have simply given up trying to comply in places like Kalifornia. Every 1-2 years they pass some other piece of shit law which requires me to alter my rifles AGAIN....

Dude! You forgot to redact the serial number!!!
Wait, what????
Need 30 mags and 1200 rounds but otherwise love it
Is that a 30 caliber clipazine with the 30 bullets in half a second feature? Asking for a friend
If it is "green", the bullets can go all the way through a tree, a car, and a small truck. All three of which will instantly burst in to flames or explode. I've seen it in movies, so it must be true.
They're not black, are they? Black things scare me...
NOW you're talkin like a leftist. Black things do tend to scare them
Buried at the bottom of a lake? Oh wait poor thing is already a ghost.
Its so purty!
They now offer these that are already anodized black. For those who can’t cerekote their own. I love it just how it is.
Well, Casper was a frienldy ghost so there is that....
The friendliest ghost around! 👻
Bet she's really friendly... Unless your a terrorist.
👌
Ghost guns deserve a third pin...
Does it have a 30 caliber clip?
I believe you mean three spare mags, or are you running 40 rounders?
Also, should be 121 rounds. "YOU FORGOT ZEE VUN IN DE CHAMBER!"
Spooky
Forget the sticker. Engraved that shit pede
She’s beautiful in all her ghostly glory.
That is a bad ass looking lower.
Milled lowers look badass. All the tool marks.
There are lots of good ideas here for finish, I have been using Birchwood Casey “aluminum black” for touchups, it will also do large areas, if you follow directions and were to “soak” your entire lower in some sort of container
You misspelled “12,000”
Ghost guns = best guns
is that a saint?
What are you gonna do with 120 rounds? Piss someone off for 2 minutes?
120 rounds can readily handle 6-10 bad guys, especially if you're the one who initiates the contact.
I want to do this but I had heard of possible deformation of the trigger pin holes over time without anodizing the lower. Have you experienced this?
Are you going to do the cerakote yourself?
Liberal here.. need protection.. I voted to take those away and defund the police. Got room for 1 more?
Not if you're still a libtard
Butt butt......
Good job y'all passed the test
rip california pedes with lots to lose :(
Midway has been out of aluminum 80s for months now.
I recently bought some from JoeBob’s, but they are out
Just last week I bought ONE Anderson here; they have a limit of one per household, one is better than none, maybe you have “frens” PRIMARY ARMS
Never used this place (billet, not milspec) maybe call them, if they are in stock, your jig may work, YMMV

Yea you just down load the plans online and 3D print all the parts! Lower, barrel, and bullets!
Sweet! It's that easy?? Downloading now!
Yea, pro tip tho: paint the bullets blue or the gun melts
Holy hell. What would I do without you. Thanks bud!
you betcha! ;)
