Ar-15 lower 80

[Twist7d7]

Hello fellow gun lovers. Today I was talked into buying a ar-15 lower 80, the guy at the store made it seem like it would be easy to find someone to mill out the trigger box. It has proven to be very hard. Do any of you guys know where I can get this milled? The lower was made here in Maryland

Only a FFL07 may finish the 80% lower for you. Any non manufacturer would be breaking the law to finish it for you.

Why don't you do a little researching? It's not impossible to finish yourself, and it's a fun project.

You might be able to find someone with the right equipment who would let you come over and use it if you bring beer.

That's one thing I'm looking for. I really want to get this done. I have a drill press but I really would rather have it done on a mill. I don't think I could manage building it myself.

Do they have any more?

 

[Twist7d7]

Yes they had 6 and they are Very high quality. Do you have the tools/know how to finish them?

 

[Twist7d7]

And if I was to go the drill press route what would my tolerances be like?

 

[magnumpi]

I have never done one but have been researching it. I have a friend that has some equipment who can hopefully show me how to do it. If I can get one reasonably enough I will give it a try.
Here's a link with a lot of info

ive done a ton of research on it. the more i do the more i want to get it milled. maybe the second one i build will be a drill press one... anyone have access to a mill??

You may need a fixture to secure the mill/bit to make it easier to do on your own. It is a guide that lays out where to mill the trigger pocket and so forth. Also known as a jig.

If i can get my hands on some would there be interest?

ETA: Where did you get these?

 

[Twist7d7]

i was looking at some on cncgun.com. this job is just to intimidating for me at the moment. i dont think i will be able to get it within the needed tolerances.

 

[crfakm4]

Tight lipped on where you got them huh?

 

[Twist7d7]

continental arms. hehe i might want another one just incase i mess this one up.

 

[Twist7d7]

Get a Jig ! its the only way to clamp it down and get it right. I have blueprints to a lower receiver tho . But i still bought a jig. i machined my boys each one and had em custom engraved . Hopefully they will appreciate something that was built by there dad one day

This is the right answer for a first timer who is NOT a machinist. With a jig these are not hard to do, I wouldn't call it dead simple, but definitely within the reach of most who are reasonably handy. It takes me a while to crank one out, but it's very satisfying to know you built your own lower.

You didn't make any mistakes by buying one. It's a cool project. Now, I have a 10% (forging) that's a complex project, and as a result, it's still a brick.

It would be great if we could get someone with the proper equipment and knowledge to put together a "build party" like they do at aresarmor.com in California. They set everything up and you do the work to keep it legal. We could all chip in and buy the jigs and maybe "rent" the shop time.

I have two jigs for drilling and milling out the FCG pocket and all of the holes. All the bits too. I'm happy to make them available to those who want to do it.

mpickering thanks for the generous offer. I will take you up on that if I can find one at a decent price. Did you use a drill press or a milling machine?
