Maybe this will be a bit on the identifying side, but I've been wanting to build my first ar-15 for like 6 years now. Once I finally had the money and was looking at the parts though, I thought:

: The primary advantages of the 5.56 cartridge is that it's small size and light weight allow you to carry lots on your person, and pack many rounds into one magazine.

: Since you live in a place with a 10-round magazine limit and are not a soldier on the march, neither of these benefits particularly benefit us. Perhaps a caliber less hampered by the laws of man would be more suitable.

: If we are to be limited to ten bullets, they should be ten of the biggest bullets you can stuff into a magazine

: Well, the biggest round that's both controllable and affordable, of course

: Yeah, yeah...

: One such caliber comes to mind immediately. An icon of the last century that survives, dinosaur-like into this one. Portable-ish, light enough, renowned for it's killing power, and extant in vast surplus war staches throughout the world. The 7.62 by 39.

:Comrade bullet! That 230-grain pencil lead that has signed countless uprisings and revolutions! Millions have carried it like a companion on the path to total human liberation; now it's your turn.

: It may not have the same velocity as the 5.56, but it's twice the weight and has better terminal ballistics. Which is to say, a more dramatic and horrifying effect on a target.

: And the kick! We've fired an AR-15 before, remember? It was like a baby space gun, hardly any kick! You need something bigger, something that'll remind you you're alive!!

:Okay, sounds like the big bullet is for me. Aren't AKs pretty expensive though?

: These days, there are all sort of things you can do with hybrid parts. We can build an AR15 that fires AK47 rounds and feeds from AK47 magazines.

Conceptualization-Easy (success): An AR-47, if you will.

: If we make it from parts, we'll have to make the grip and stock ourselves. We can practice our woodworking and engraving!

: I'm pretty sure they have those things for sale too

: Nope, we must. It will be beautiful and custom, or we will not do it.

: Lasered wooden furniture, hybrid appearance, brass fittings...people are going to wonder why and how some sort of 1920s vampire hunter has made it onto a modern day range. Best wear your most stylish coat.

: A beautiful mutant for a beautiful mutant: how fitting.

So now I'm waiting to pick up my hybrid AR lower that takes AK mags, and slap it on the upper I got. Then it's woodshop time baybee
