Lower is one of Kevin's 80%, completely finished.

Part's kit for the lower is from Sportsman's Guide.
Upper is an Oly Arms 40cal pistol with M4 Handguards and 11" barrel.
Receivers and barrel and front sight forging finished in SFL gray.
Pins are KNS QD type.
Buffer tube is a Model 1 Sales Pistol tube.
I'm pretty happy with her, and had her to the range this morning. Functions perfectly, and looks fantastic. I have a new love.... AR pistols!

Whaddaya use for an IWB holster? :D
It's easier just to prop it against the wall, beside the bed... :D
Anyone else here ever build their own AR from a forging or 80% receiver?

This is the closest thread I could find to "finishing my rifle"
One of mine is a REM.700 in 30-06 stock barrel.
I put it on the Plaster Sniper stock a few years back, and last year up graded the trigger (Rifle Basix), and yesterday I finished cutting out the bottom and replacing the Bottom metal to allow a Mag well. I baught the "Kwick Klip" set up and two 10 round Mags.
A lot of Dremel work but it's worth it. I'll try to get some Pics.
Oh...Scoped with a BSA (no problems with it in 6 years).

I looked into it, but, IMHO it is not worth buying all the tools to make one to build one receiver. Also cast less than 80% receivers that I have cost more than stripped 100% receivers.
Also it requires some good machining skills, patience and....
True, but with the 80% there is no paper, or serial #. The only tools I actually had to buy to finish mine were the extra long aircraft drill bit for the bolt hold open lever pin, and the tap for the pistol grip screw hole. Other than that, I used a drill press with mill bits, a vise, and dremel sanding drums to complete mine. The buffer tube threads were already done, and I had all the bits for the lower parts pins and such.
It works very nice. I'm going to be building a nice SBR as soon as ATF gets off their (well you know) and gets my form 1 back... Oooo the fun...

Buying from a private party, no paper either. I have seen just the raw casting. Sounds like you got a good partial to work on.
Thanks for the photos.
While doing a search for "Kevins 80% Lower", I came across this site re: CNC gunsmithing:

Latest News:
12/01/08: Great news!!! I just designed and test a new milling adapter kit to help you remove the material from the fire control pocket in AR15 and AR45 lowers. You no longer need a big milling machine to remove the material from the fire control pocket. It can all be done right on your drill press. Visit the TOOLING page for details.
I've completed tutorials on how to finish an 80% AR15 lower receiver using the CNC jig and the milling adapter kit. You can view the tutorials at this link.
I still have a few 10% AR10 lower "paperweights". These won't last long, so if you are interested, please contact me ASAP. You can get more details on the CNCGUNS forum in this link.
I have the 10% AR45 lower receivers in stock and ready to ship. For details, go to the bottom of the AR45 lower receivers page. I also have a few A1 carry handles left. If you would like to buy one go to this link A1 Handles.
Yes, SF, CNC guns is where I found Kevin's contact info. I bought two 80% receivers from him last year, and finished one into the pistol. Debating on what to do with the other. (I actually bought two in case I FUBAR'D the first one. It was so easy to do, the first one turned out so well...) I might put together another 40cal pistol to match this one, with a left side ejection port... They would go SO well together. :D The drilling jigs they make look nice if you plan on making a few receivers. I just had two, so I did everything by eye and careful measuring. The FCG pin holes I actually used a tracing of another complete receiver, and a center punch to position the holes for drilling. Worked simple.

I have a maintenance question.
I have a 1860 colt repro by (Uberti) and at first it would Half cock allowing the cylinder to spin (for Loading) after the first disassembly and cleaning. It will not half cock with the cylinder free rotating. I disassimbled it totally and reassembled it without changing anything and it still doesn't free rotate. There is a position just before Half cock" that if held there will allow the cylinder to rotate. It looks like a "timing" problem.. Any suggestions? Blitzzz

It's not a Pistol, but you may find it interesting. (It's from about 5 years ago)

Great photo. This is one of my builds and conversions to closed bolt.

Neat to know we have a number of builders on this forum. Currently I am working on trying to figure out how to do the semi auto firing group on a RPD. I have the closed bold figured out.

Probably worth a bump considering current gun politics.
Not sure how far along cncguns drill jig was 4 years ago.
Looks to be fairly user friendly.

I have just finished my second lower receiver but I have a background in manual machining.
I used 80% billet receivers and the jig from Jagernaut Tactical since the receivers come anodized leaving only the FCB needing to be finished. I also did not utilize the initial drill jig designed to remove the mass of the metal from the FCB. I center drilled a couple spots then drilled the mass out leaving about .030" at bottom to finish with the endmill.
To the point of using a drill press to finsih these off: if I were going to assist family/friends and didnt have access to a fullsize vertical mill I would purchase a smaller benchtop mill (around $1,000.00). While I am certain these could be completed with a drillpress the quality of work isnt going to be the same and it will take you far longer. I would also purchase two flute endmills instead of 4 flute endmills - 2 flutes work better on softer materials.
Now if I could find a 80% billet upper...

Does the prosthetics shop know what you are doing with their machinery? :D
The upper requires a huge bit and a long travel machine to cut the space for the bolt carrier longitudinally. The lowers are much easier.
Hence the reason that so many companies make lowers, but buy their finished uppers from someone else.
Very nice work, BTW, I didn't know you dabbled in metal, as well as flesh.

Yes, very good job. FYI, using the drill press does take some time, but I can usually knock one out in an afternoon. I just finished two more. One for a 24" fluted upper I bought from Rguns, and the other as another pistol with a 7.5" barrel, 3 prong FH. For me, it's all about the fun of doing them. If I only wanted one, I never would have bought the jigs, but if you are doing several, in order to sell off your "papered" receivers... they are worth the investment. Using the endmills and side mills to clean up the drill marks works nice. Thanks fo the tip on the 2 flute as opposed to the 4 flute. I need to buy a few more end mills and such. Mine are getting dull. I have a friend that anodizes them for me for free, and have a few more to send out this week. One is a 45 lower that uses grease gun magazines. That is going to be my new home defense weapon. I will post some photos when I get it done and back. It will then be papered and made into an SBR eventually perhaps... Perhaps not... Might keep it a pistol. We'll see on that one. Depends on how it works out. In this day and age... it is the way to go.
Lowers 80% used to be 80 bucks each when I first started doing mine, so I stocked up... I see they are now 120... You gotta buy low! Hahaha... Everything went through the roof though. If anyone wants to do something like this, and has any questions, let me know and I will help you out. GROG

The uppers would require a bit more work but on a bench-mount verticle milling machine there is more than enough table travel to account for the length of the bold carrier groove.
Yeah, I worked in a machine shop building jigs and dies for CNC machinery in highschool. I knew the investment in tooling and exuipment would one day pay off. Thanks to the President I have decided to build a few guns under the radar.
To echo Grog, if anyone decides to undertake one of these and wants some advice please feel free to ask.
