Seven Minute Del-Ton AR-15 Kit Build Step-By-Step

Are you like me? Do you have a few spare AR-15 stripped lower receivers laying around that need rifles built from them? Now is a *great* time to build an AR-15 because component prices are low, and kits/parts are in stock! For years I’ve been wondering about Del-Ton kits, and I’d like to share with you my experiences building out an AR-15 rifle from one of Del-Ton’s kits!

I got my Del-Ton kit from Midsouth Shooters Supply who sells of ton of AR-15 rifle kits, parts, and accessories. In fact, the 16″ M4-style AR-15 carbine kit I’m showing in this article/video is the most popular rifle kit Midsouth Shooters Supply sells! I really enjoy the feeling of having put something together myself, so I prefer to build my own rifles when possible.

Here’s whats in the picture above, which shows what you get with this kit:

  1. Upper assembly (charging handle and bolt removed)
  2. Charging handle
  3. Bolt
  4. Lower parts kit
  5. 5-position buttstock with buffer and buffer spring

And here’s a complete walk-through of my rifle build, complete with a quick range trip: (condensed build steps are just 7 minutes long!)

As you saw in the video, all of the work to build a kit like this is related to the lower assembly. Here you can see all of the parts (minus buttstock, buffer tube, buffer, and buffer spring:

And here’s each of the parts groups pictured above:

  1. Stripped lower receiver (not included in kit: also need magazine(s) and rear sight, both of which are not included in kit)
  2. Magazine catch parts
  3. Bolt catch parts
  4. Buffer retainer parts
  5. Selector parts
  6. Trigger and hammer parts
  7. Grip and trigger guard parts
  8. Pivot pin and take-down pin parts

The build went smoothly, my sight-in was right on without sight adjustment (when does that happen?), and this rifle has performed 100% for the 100 or so rounds I put through it so far (looking forward to many more!).

The quality of the parts included in this kit is quite good- fit and finish looked great, and everything fit together nicely. Here you can see me inspecting the upper assembly as it came in the box:

    1. Because it is a good compromise when shooting heavier bullets (which seem to be all the rage these days) as well as most lighter bullets, too.
