Default Just milled out my first 80% lower

I just milled out my first 80% lower and started putting all of the parts in it. Figured I would take a picture before I got everything put together, and then update when it's completely finished. The lower and jig set are from 80% arms, the tools I used were a Crafstman Router/Drill and a table mounted vice. The milling process took about 3 hours, and I've been working with the parts for about an hour so far.

Did the sides turn out pretty smooth? Did you use the plunge capability ?

The sides turned out very smooth. I used the drill bits that 80% arms sells in their store, so the router bit had a 1 inch tip and the rest of the bit was all shank which meant that when I was routing it out, I could touch the walls with the shank and it wouldn't tear the jig or my lower up. The plunge capability, do you mean the part that allows you to resize the depth? In between each pass, I would measure how far the bit went in, and then resize the router to 1/3 to 1/2 of a hash mark, lock it, and then do another pass. (the hash marks that you use to measure the bit that came with the jig set)

Edit: I also took a buffing tool with a cotton tip to smooth out some of the holes that I drilled just so they weren't as sharp along the sides

I think you'll find it will also be pretty easy. The main thing to remember (and they talk about this in the video tutorial) is when doing the routing, take your time. If it's not cutting like butter, then you've either move the drill bit too much from the last pass or you're going too fast. Something I had to constantly remind myself of. Take it slowww.

Thumbs up

Well done, man!

Once you are satisfied with the operation of your assembled lower ( and have tested it), you can use a set of the KNS anti-rotation pins to conceal the lack of anodizing around the hammer & trigger pin holes.

I keep an eye out for Primary Arms sales where they put the KNS pin sets on deep discount. It pays to keep a couple sets on hand. Again, nice job!

Trigger seems great! It came with a parts kit that I bought at a local gun shop here in the central valley.

I was reading about some other people doing that as well, I'll look into it. Thanks!

Weird gap between the trigger guard and the grip.

I've made two so far. Almost have enough parts left over to make a third, but I'll probably hold off until my finances recoup a bit.

I had my suspicions. I'll fix it now, thanks.

The grip didn't have the screw in the bottom of it yet.

Attached are the two that I've finished. The bottom one is a 20 inch barrel with a 16 inch rail. I feel like I should probably try to find an 18 inch one so that the barrel doesn't stick out as much. What do you guys think?

Lol...I know exactly what you mean dude. I'm saving up for a 300 blk and I've got plenty of completed lowers just waiting to be assembled.
