80% AR15 Lower Completion

[Riven]

I have the LMS and I am going to CNC mine, I plan on doing a 45 acp and also a AR15 on mine.. When the time is right..

OakRidge didn't mention jigs (oops, maybe he did - ?LMS?) but I'm assuming that if he's going to CNC them then the commercial jigs are unnecessary - a couple pieces of aluminum shaped to the outside of the receiver will do fine.

If using a hand drill or press than I'd want a commercial jig, but right now I'm shaping jigs per Ray-Vin's manual and plan on using those with a BP for probably a 20% forging (or maybe a zero, I haven't decided yet).

For a jig, look at cnc guns.
+1 for the rayvin guide but also take a look how Justin did his at cnc guns, I got ideas from both. I am not finished but started with 0% lower.
Take a look at goobers posts there, lots of knowledge and nice guy.

Blackhawk, do you have a link to Justin's build on cnc? I am getting ready to start a 0 and want all the info I can get before I decide on how to do it!

Thanks!

Here is the link to cncguns lower, http://www.cncguns.com/projects/ar15lower.html. this and the ray vin guide helped me get as far as i have with mine, im about 90%. Here is another link that was kind of interesting, http://johnbearross.blogspot.com/2012/02/you-cant-stop-signal-homebrew-ar-15s.html

Are you going to do this manual or cnc?

Awesome, thanks very much! I'll read up on them tonight.

I am going to do this one old school. I have a DRO Bridgeport that does most of my milling work at the shop, so that will be the tool I use. Only issue it has is that the Z axis DRO doesn't work and I haven't figured out yet how to get the auto feed to work for the X and Y, but that hasn't really caused my any issues yet and I don't foresee it being a problem here on this build. I'm going to start with a 0% forging, have a couple backups on the way just in case I make a big mistake... LOL
