How To And Tips For Milling An AR Lower From An 80%




What do you think about this video?

usmcdoc14: I am replying so I can delete your post. TAS Firearms, If you wish to get exposure off my work then you can send me some of your products to build and evaluate. There is no free lunch, only my free instructional videos

FuYing Bro: I love your PSA. Although I did an 80% on a $130 drill press and $40 x/y vice. Of course it didn't come out as good as yours. I was just saying that you can do it with less that what is shown.

Chris Turnblom: I disagree with your definition of assault weapon. The term is completely ambiguous. If I assault you with a spoon it can be considered an assault weapon. Just because a gun shoots automatically does not mean you can only use it to assault people. Don't give the idiots any ammo.

ChickenPimp J: Where did you get your spec papers? I ordered two of the alum lower 80's and got nothing as far as drilling depths. I didnt get any specs nor, even, a website to go to for looking at any specs. If I ever order any more Ill be going through a different distributor (unless the guy starts adding some info on machining and building these things). NM, Im checking your website, now...maybe Ill find what I need. Semper Fi!

michael N: ... less rhetoric , more facts...

rdsii64: finally knocked out mine last night. I was up until 3am. its not as hard as most people think. YOU DO HAVE TO PAY ATTENTION TO WHAT YOU ARE DOING THOUGH!! I under cut my fire control pocket by 2 or 3 thousandths because I knew being a novice it was going to come out looking rough at best. One final skim pass this morning and this baby is ready for a parts kit.

megadeth22885: a drill press with a 2-axis milling vise for a drill press is realistically all you need to do this, $100 for a cheap drill press and another $60 for the vise.. plus the proper endmill bit

AZ DieselTech: No gloves! Everyone wants to wear gloves. Glad that you're not, and you made a point of stating the obvious for the beginners. You snag a finger you can pull it away. You snag a glove and it pulls you in, you have ground beef. Great video. Learned some things, and knowledge is the most important thing we can arm ourselves with. 

Emil Pienczykowski: Thank you for your patriotic spirit and teaching. Hope to see more people like you.

Christians.Vs.illumination: USMCDOC14 your video has helped me tons! I would love to see you build a Radius 1911 build.

Haywood Jablomie: Is there such a thing as an 80% .50 cal kit??

rdsii64: Well I pulled the trigger last night at work. During my break, I ordered a solid column Sieg X2 and a belt drive conversion. I'll order tolling later this week. looking forward to going back over this video after my mill has been delivered. Lucky for me the 80's I have came with accurate drawings. Now its lots of studying and messing around with scrap aluminum to learn my mill. The fist hog I kill with my new rifle I will dedicate to freedom and the second amendment.

William Hall: Great video! Thank you

michael neyman: mute, take it easy pencil neck

matt lemon: bless you for teaching the populace.... knowledge should be open and free for the people. Governments will try. But people like you are keeping the hope alive.

nunya biness: For those who have a better mill, use a 7/16 cutter. The radii in the FCG pocket are supposed to be .218. I run a 4 flute 7/16 with a 1.3" cut depth at 1,000 RPM for most of the process (I do the main pocket in two steps), then kick it up to 2,500 for final pass, climb milling ~.010" material. Personally, I like to cut 7075 al dry; easier chip clearing, and won't hurt cutters at all if your speed and feeds are right. Having said all this, if you're using a bench top, as he mentioned, they simply won't hold the tolerances, and the lower pocket that is supposed to be .438" (7/16) at the selector lever will grow on you. I spent a long time with the little Seig/HFT mill; it'll get the job done, but you have to take light cuts and constantly check your dimensions. Tighting the gibs will help with chatter, but makes those little cranks very tight, which *will* cause carpel tunnel over time.

Anthony Seneck: I Agree with everything you have said in this video

Kyle Hobson: Hi im 14 and really want an ar 15 im one of those "zombie prepper" types and want one for my survival kit and also for hunting as I know that the ar 15 is a very reliable and comfortable gun for me I want to know if you have any idea if it would be legal for me to manufacture and own one please reply it will be very helpful btw I will be 15 before I can get ough money to buy the parts

Michael Costa: I am with you, I am not a criminal. 

Jordan Baumgardner: Thank you, for helping truly protect this land and it people.

Haywood Jablomie: What a GREAT guy!! A real American!

Y Pop: I had to unwrap a man's hand from a drill press because he was wearing gloves! I never ware gloves when machining! 

rdsii64: Been watching your videos. Love your work. I have two DPMS pattern .308 80 pecent lowers in my safe. I am about to pull the trigger on a solid collum HiTorque mini mill. Once I save for a three axis DRO and the tooling, I'm all in. Hell I might even try to make a video of my progess. If I take it that far I will be sure to credit you as a source. Semper Fi Brother

Gabe Hartman: DOC are you a green shoe or brown shoe, my brother is a retired Navy surgeon, who was assigned to a Marine unit. Oh and thank you for this info, I love it.

Sean Talley: You sir are my freaking hero I really cant express it enough. They can take my guns from my cold dead hands. 

reado33: can someone please tell me how many times this guy says OK is it more or less than 761 times?????

MasterK9Trainer: I appreciate you putting yourself "out there" and it's one thing to read books or plans, but it's invaluable to see someone actually do the work to demonstrate what it takes, what is required and how hard or easy it is to do a project. I have two brothers and we were born in Quantico, Camp Lejune and Cherry Point, so I support marines. 

xmodfreak2011: That calipers advice is golden. Was using some random manual calipers (like ruler status, not even a dial), totally read it wrong like an idiot, and punched thru the floor of my lower. Epic. Fail.

kpw528: +usmcdoc14 Just curious, I saw you say somewhere in a comment that you were from Virginia. What part of VA do you live in? I also live in VA and it'd be awesome if you were in driving distance, so maybe I could come over and you could teach me about milling an 80% lower. I'm really interested in building my own AR, and the concept of 80% lowers is awesome to me because I'm a hands-on type guy and love building/working on things. Semper Fi and thank you for your service, and for the awesome informative videos!

thomas lowe: Hey i got a question for you, im about to start on my first Ar build, im using the jig from 80% the easy jig, and the only things i need are the drill stop collar and the router, (and of course the complete upper receiver) and i was wondering what size and type of router bit would you suggest to use on finishing up my lower, i have the general idea of how to do it, just need some specifics now on the router bit to use

Stresscat1: I did not see the VZ-58 build on your sight. Could you do a VZ-58 build using the Hellbox Armory 80% receiver?

Argelio Del llano: What's the law on this 

Cameron Henrichs: Could you mill mine for me ? 

The Rodog: @ 16:51 love it

Johnny Maggiore: I didn't even know what a drill press was until I watched this video. I have watched this video several times before, I really want to start building my lower soon. I am very excited and this video will really help. The only part I was confused on was the drilling depth I need, and the bits I will need. That's all, thanks.

YungBossk: Quick question. I see your 80% doesnt have a trigger guard. But on the website you give billet80 all the 80% they have come with non removable trigger guard. Did yu buy lower from different website? Just need to know bcus I need 1 without trigger guard for the grip I am using

Steven Ford: Great skills, nice work, I'm a fan. O.k. Now that it it milled what about the finish? Do you prefer to powder coat or anodize and die? I'll keep watching your stuff. Love your abilities and your attitude.

Anthony Seneck: +usmcdoc14 Have been wondering what state do you live in? If you don't want to answer that I understand as well.

UncleDeluxe: Nice video, thanks! On a side note- damn, there are some douchey blowhards on your comments page for your free video, that you spent the time making, which they have absolutely no obligation to watch if they don't want to.

Phu Ly: Thx for the guide, very much appreciated for taking your time in making this video.

Sir David Haddon: ooh rah, Second Amendment, and Free Speech ! Thank You for the schooling.

Alex Fernandez: Is the lower still good if I overcut like say a tenth of an inch or a hundreth of an inch?

sosocrazy1234: hes right, the founders were smart and they were students of historical warfare and they damn well knew the evolution of battle and battlefield tactics and weapons over time. they intentionally used the word "arms" in the second amendment because it is used to refer to all forms of modern weapons, otherwise they would have said "muskets." people who say "arms" refers to and is limited to a musket needs to be kicked in the head, because they are stupid. plain and simple...

spencer han: This guy rules....freak trolls

Robert Russo: please make a video on how to do the tramming on this mill thanks

Ben Raines: This video is outstanding. Everything is explained in great detail for accomplishing this task. I think this is the best video for milling an AR lower available. I agree 100% with your politics! If the gun owners don't stand together we will fall individually. Take a stand! Thanks! Subbed ya!

Johny Vegas: freaking awesome! I trust the people with the guns way the freak more than I trust the government with them. At least with the people, the majority are going to average out and eliminate the influence of the most destructively radical. If the government could build an army that wasn't made up of its own citizens, we would have been completely enslaved years ago. Eventually, I'm sure they will remove all human decisions from war, both abroad, and eventually against us, except orders from the very top. Look at the robots that Boston Dynamics have been building for DARPA. I have no doubt that they will deploy fully autonomous killing machines at some point that are under the direction of a few people. I think if our government no longer served the interests of the people of the United States, traditional weapons would become partially obsolete, and explosives would become an increasingly important means of defense against an increasingly non human army. As I've read in Popular Mechanics recently, they are working on making fertilizers that can't be used for explosives. We might be wise to master techniques of producing explosives as well. That scene from the original Terminator comes to mind.

reado33: OK OK OK OK OK
