Welcome, Chase! The anodizing shop should do any surface prep work but some raw receivers need more work than others. For example, I used a Nodak Spud receiver and it needed to have some casting flashing sanded off. If you're going to have the receivers engraved you might want to do that before they are machined into "firearms" so any engraving shop can do the work and not just a shop with a license to do so. The same goes for the anodizing. If it is machined into a lower receiver the shop will need a license to work on firearms. Cause government.

Thanks for the warm welcome, Jefe!

As far as the FFL restrictions, I've already considered that. Fortunately, both my local jeweler/engraver/gun pusher and the local anodizing shop are FFLs. Having said that, though, I think I'll go ahead and have any engraving and anodizing done before any work is completed on the lower.

If your guys can do the work after machining then definitely do that. You don't want to put money into engraving and then have the possibility of screwing up the lower, especially on your first one(s). And ideally anodizing should be done after machining so the parts you drill/mill will be anodized and dyed too.

Do you have a link to the reamers you bought/used? That actually sounds like a better plan than a plain ol' drill bit anyway.


Well you are still going to need to have a drill press. When I drilled out the hole i had to align the drill with the hole making sure it was in the center since it will be smaller than the hole on the jig plate. Then drilling it and if you can find reamers that are the same length as your drill you can just switch them and ream right through. But reamers are tipicaly longer. I'm actually a tool grinder so I made my own reamers. There are a couple of websites that you can get reamers from. Most places sell them in sets though.
 
Hope this helps.

I did not have the drill stabilizer. My buddy has it and it still feels looser than I would like. I recommend that if you do use the hand drill set your jig on the ground and get as sturdy as possible. The side without the detent hole worked OK but didn't have a good finish but would work. I ended up getting some reamers and thats how I will do the rest of mine.

Howdy folks! My name is Chase, and I'm delving into the world of 80% receivers with a bit of goading by my father in law.

I've built a couple of small frame ARs from 4473'ed lowers, and my FIL started asking me about 80s. So I decided he and I will build a rifle for him this year for Christmas. From an 80% lower (which he will do all machining work on).

I've ordered up an Easy Jig G2 and the necessary tools, and just pulled the trigger on a raw 80% Cerro lower and raw Cerro upper from RTB. I'm planning on having both the 80% and the upper anodized at the same time by a local anodizing shop (trying to ensure a good color match, and I ordered deep safety engraving).

My first question: Are raw receivers ready to be anodized as-received? Or is there some fine finishing that needs to be done beforehand?

I look forward to learning a lot about 80%s and the process. Maybe even contribute a bit once I learn some stuff.

The drilling I messed up on. The safety selector hole has a detent hole and when I was drilling though the drill caught that hole and whipped the drill around and over sized the hole. yes I was trying to do this with a hand drill because my drill press was to small, I do not recommend using a hand drill. The holes on the jig plate have to much slop to ever get it right. Now it did work just fine for the trigger pins.

Did you order/use the 'Hand Drill Stabilizers'?

I'm curious, because I just ordered an EJ2, with the stabilizers, and am hoping those will help with the slop you described.

If anybody is still interested in engraving on the Ghost Gunner, check out - https://ghostwriter.serverrack.net - You can download DD files to use for engraving for free.

Alright so I finished my AR 15. Im very pleased with the results I got from the milling, the finish is very nice.

During the milling I noticed that a lot of chips build up around the bushing which really does not matter for the straights, but coming around the corners the chips keep the bushing from going into the corner completely. What I recommend is every third pass or so clean everything out and wipe the jig plate, and bushing. Then come in and clean up the corners nice and slow.

The drilling I messed up on. The safety selector hole has a detent hole and when I was drilling though the drill caught that hole and whipped the drill around and over sized the hole. yes I was trying to do this with a hand drill because my drill press was to small, I do not recommend using a hand drill. The holes on the jig plate have to much slop to ever get it right. Now it did work just fine for the trigger pins.

Since I am a machinist by trade I went and made some .502" brass bushings and drilled and reamed the hole out to .500" and press fit them in. It worked amazingly all I had to do was borrow my buddies drill press.

I could not post a picture on here but if you have Instagram come check it out. @machiningfools

PS. I just ordered an AR 10 and AR 9. Will post about those also for the easy jig gen 2
