Thank you for the warm welcome in the 'New Persons' post!  As promised, here is the start of my first build of an AR 15. 

Here are two MilSpec lowers:

My first build will be with inexpensive parts.

 

Question: MilSpec is MilSpec so is there really any difference in different lowers?  An expensive lower isn't going to make it perform any better than a inexpensive lower is it?

No matter who makes them there can be small tolerance differences in parts. Don't sweat it just yet. When they are completed you want everything to work together.....the magazines should drop freely, ammo should feed properly, etc. Any maker can have a bad day and get tooling off a tad. Different brands hold those tolerances to higher or lower standards. I have two lowers that won't run certain magazines because of tolerance issues.....but they run flawlessly with others. It may be the lower itself or it could be an issue in the parts kits. Every individual part has a tolerance....stack up the fat ones and things get tight, get all skinny one's and things go the other way.

 

You have milspec 80% lowers....they will only be as good as you make them. You mess up your end you will have milspec paper weights. :tiphat:

Thanks for the input towtruck! That's why I got two. They were cheap!  If I mess up on the first one, the second should be good.  If both turn out good, then I'll have two lowers to build on. :)

Get a good jig, get good bits, follow the directions to the letter, don't use a drill press, and go slow......there is no reason to mess up any of them.

You mean I shouldn't just use my hand drill and Dremel tool?  :tongue:  Just kidding.  I have an 80% Arms Gen2 jig.  They seem to be really nice but i need to remember to go slow.

Here is the Easy Jig Gen 2 from 80% Arms. It is suppose to be one of the best.  It will do AR9, AR15 and AR10 and it seems to be well designed and build:

Never used one like that. It does look like a good jig.

Haven't been able to do much this long weekend with a lot of things going on.  But I was able to drill the pilot hole in both the lowers.

 

First three pictures show the lower in the jig.

Some more progress this week.  Got both lowers milled out in the 80% Lowers Gen 2 jig.  I used a Mikita compact router to mill out the fire control area.  The jig has set depth increments for advancing the mill bit about a millimeter at a time.  These lowers are 7075 billet aluminum, so it was suggested to use half a millimeter increments.  Used some tap magic at each depth and cleaned the chips.  The first lower took about an hour since I was being real careful.  The second only took about 30 minutes.  I got the extra drill guides in case I needed to hand drill the Safety and trigger pin holes and tried them out.  Worked really well.  Here are some pictures.

In the jig and milling with the Mikita:

Finished milling:

Finished milled and drilled lowers:

Ready to start assembling lower:

The whole process was really easy with this jig.

 

More to follow.

Welcome to the board, Sir. 

This is already one of the best intro threads I've seen,

because you are documenting the 80% lower and the rest of the build.

 

I look forward to following your progress on the build, and thanks for all the pics. 

It might be nice to give the brands of some things, and no matter if they work well, or work poorly,

it is simply additional information that I think would be nice to have. 

 

Have fun !  (Like I need to tell you that)

 

John

I am retired from the military. I always wondered about the term milspec.  Because the weapon is built by the lowest bidder who passes the tests or is good at greasing palms.

 

Welcome.

Thank you all!

 

RetCop: The Jig came from 80% Lowers.  The 80% lowers as well as the lower parts kit came from Ceratac.

 

Got everything from the lower parts kit on with the exception of the the buffer tube assembly because i lost one of the detent pins for the pivot pins.  Was trying to get the forward pivot pin in and the detent pin went shooting off never to be found.  Used the other detent pin, so now waiting for another detent pin for the rear pivot pin to come in. :tap:

Picture:

Mag release/catch works. Performed the trigger function check.  Hammer fires when the trigger is pulled, does not fire when the selector switch is on safe, and when the trigger is kept pulled back after firing and then releasing, catches on the disconnect.  YouTube is wonderful! :tiphat:
