My first AR build...

Just wanted to post this: My first AR build. Bought a Del-Ton stripped lower from JSE surplus and then got a Del-Ton mid-length flattop kit direct from Del-Ton in NC. I read the assembly instructions on AR15.com and downloaded the video, and it went together pretty easy.

In fact, as mechanically inept as I am, I can offer myself as proof of how easy it is: If I can do it, pretty much any primate with opposable thumbs and simple hand tools can do it! ;)

Here's the finished product:

As you can see I went with the mid-length upper rather than the carbine-length upper. Since I use iron sights I figured the extra sight radius would be a benefit. Also, since the actual M4 carbine has a 14.5" barrel and these civilian rifles are required to have 16" barrels, I think the mid length looks more "correct" whereas the carbine-length handguards always make it look like the barrel is too long IMO.

Haven't had a chance to shoot it yet but with it getting warmer and warmer, the mountain shooting areas will be accessible soon!

EDITED TO ADD:
If anyone out there is "on the fence" and wondering if they can really do it, the answer is YES, YOU CAN! :sombrero:

You can also save some money (~$100 - $150 over buying a 'built' rifle) and get the exact rifle you want.

I should also point out that the Del-Ton kits come with the upper receiver/barrel assembly fully assembled, so all that needs to be put together is the lower receiver and stock. I may try to assemble an upper next!

Looks nice!

Did you assemble the FCG or did you buy a drop-in?

FCG = "Fire control group" I assume? :confused:

In that case, no, I assembled all of it. A bunch of springs and things. Actually, the trigger/hammer/disconnector went in pretty easy, no problems at all. Getting those roll pins in was a different story! I'm a little bit surprised that they don't sell lower receivers with the roll pin components (the trigger guard and the bolt catch) already installed. I certainly would have paid $20-$25 extra to not have to do those parts.

Funny thing, my kit seems to have come with an extra trigger spring because I had one left over when I was done, and my rifle "function checks" just fine so I assume everything is installed correctly.

very cool. I've been debating on building mine...

I would say do it, it's surprisingly easy. I don't know what kind of hoops you have to jump through to make an AR legal in the DPRK but the assembly itself is pretty easy.

In fact, the one "difficult" part that many people complain about, the installation of the forward takedown pin/pivot pin, was quite easy. If you follow the video, they show you how to compress the spring and detent plunger with a razor knife and then slide the pin right in - works like a charm!

I had my laptop on the floor next to my assembly area and just followed it step-by-step, pausing the video after every one. That was much easier than trying to read the printed-out instructions I got off of AR15.com.

You can buy lowers with the parts in...it's just not as much fun. Good job!

not very much actually. We're limited to a 10rd mag, and that mag has be be released by a "tool". (most guys run a mag that holds ten, but looks like the 30rd'er called a 10/30..I'd just run a reg. GI 10rd'r)

To that end I have to install whats called a "bullet button" that precludes me from being able to pop a mag with my finger. So the mag is the same, well is the same, I just have to have a bullet or other pointy tool on the gun/nearby to use to drop the mag.

everything else can be built to normal standards (16" barrel, flash hider, collapsable stock, iron/holo sights, etc). Can't do supressors, but thats a small issue in my mind.

If you're going to build an upper from scratch I would suggest buying a quality barrel nut wrench. And maybe a quality drift punch of a size suitable for the gas tube retaining pin. The other special tools are handy, but with care and time I don't think they're all that necessary.

I made a scoped flat top upper for a guy years before those were available (cut up an A1 UR, no front site). Built it up with a 1:9 twist chrome bore HBar, a fixed tubular forearm (fixed only to the barrel nut), and added a case deflector (LH'd shooter) since case deflector UR's came at an extreme premium in those days.

Right on!

Fwiw assembling the upper/barrel assembly is no more difficult than the lower although it does require some tools (armorers wrench) and you'll want to double check head-spacing as well.

I looked high and low for a set of roll-pin starter punches, couldn't find any in the size I needed so I had a buddy make me a set. It basically holds the roll-pin in the end of the punch, making it extremely easy to start. I think Brownells might retail as well?

Nice job - let us know how it shoots when you get a chance.

Brownells does sell a set of roll pin punches that makes assembling the lower a breeze. Check around and you may be able to find a set to borrow, or if you're planning to make a hobby of this they are a worthwhile investment.
