80% AR Lower
 
I'm looking to maybe machine an 80% AR lower. Now, I see that they have the fixture for doing this, BUT, I have access to a milling machine with a DRO. Is there anyone who has worked off just dimensions with no jig? If so, how did it go, and exactly where do you find the dimensions?

The other thing I'm curious about is how have people marked them? Do they come marked Fire/Safe?

BTW, Ares Armor is the company I'm interested in ordering from.

There are numerous cad files online available.

I'd also look at Tactical Machining, but it does look like they are out of stock. I've bought from Dimitri @Ares Armor, his products are great, but they are seriously backlogged right now and you may be looking at a wait for your products. I'd call first before ordering.

Thanks for the link, I'll check it out. Yeah, as far as I'm aware, everyone is sold out. Since I'm not in a rush, that's OK.

OK. I'm not sure of what to do with that website. It looks like pictures of guns/parts with an attached file to machine it. I should say that while I have some machining knowledge, I'm NOT a CNC machinist, nor do I have access to a CNC machine. Also, how do I determine which ones are correct, and applicable to the Ares lower?

Use a cad program, opencad, solidworks,autocad and you should be able to get a model


Btw wat is a Dro?

Digital Read Out. Doesn't mean the machine is CNC, it just tells you the X & Y position.

So there is nowhere that you know of that just gives a blueprint in maybe a PDF format, or something?

I remeber seeing a pdf online...... ill see if I dig up another link for you. In the mean time get opencad. Its free. And 3d is a whole dimension better than 2d.....literally :)

Thank you, my friend! THAT is what I'm talking about!

Still interested to hear from someone on this forum who has done this project. And whether the lower comes marked fire & safe or not.
