Anyone here built an ak-47?

Postby newportri » Mon Oct 13, 2014 1:59 pm

I have never fired an ak-47 and I never really had a desire to own one, but I thought it would be a nice gun to have in case of SHTF and I would like to know they work. I see you can also buy these receiver flats that I think are considered 80% lowers and can therefore be shipped to your home. The nice think about those receivers are that they look relatively easy to make since it's just a bunch of holes drilled in a flat that needs to be bent. Seems a little simpler than machining an ar-15 receiver. What is considered the most difficult parts to assemble on ak-47 and how does it compare to an ar-15 as far as building one?

I've got a Yugo under folder that I like. It's not pinpoint accurate, but it's certainly accurate enough! I'd be happy to let you try it.

As for building an AK, I know that some folks from Northeast Shooters get together periodically for AK build parties. There's also a company that hosts weekend builds with an eye toward training folks to set up their own AK construction businesses.

Thanks, that would be fun to try. You are a member at TRGC, right?

Go watch a couple videos on building an AK and I think you'll reconsider the "easy" part...

I had thought about building one myself too but the outlay money on tools alone (hydraulic press, bending jigs, riveting tools) just made it completely unfeasable from an economic perspective. When you can buy a century underfolder for $400 with a couple of magazines, the ~$500 you would spend on tools alone starts to seem nutty.

In comparison, doing an AR lower is actually pretty easy. The new "easy jigs" that just use a small hand-held router make things super easy.. But again, the cost of the tooling is 2-3x the cost of a finished (and transfered) lower!

Wow, those jigs are nice. I was never comfortable doing it on a drill press due to the lateral forces, but this seems much better. Has anyone here use one? Who sells good quality 80% lowers?

I am. I'm pretty booked up for couple weeks, but let's plan on hitting the TRGC outdoor range.

I'm thinking of picking up a C39. I don't normally jump at Century's stuff, but the reviews have been very good of late and they're built with a longer length of pull than ComBloc versions.

Yeah, I started an AR lower on a drill press.. and finished it on a router.

The drill press head fell out from the lateral forces - it's not designed for the side-loading at all.

Fun fact - how do you remove a drill press head? Tap it with a mallet - SIDEWAYS! :cry:

I've been reading about a company that sells a small "open source" CNC machine that hooks up to a laptop. It's capable of finishing AR-15 and AR-10 lowers. IIRC, the price is somewhere around $1600. It's not cheap, but could perhaps become cost effective if shared by a group.

I recently watched a YouTube video by a company called Broken Arms. Their jig apparently allows much more drilling out prior to the milling stage. Lateral force would still be an issue, but perhaps not as much as other jigs. I'm no expert on this stuff.

Milling machines and routers can take a lot more lateral load than a drill press so they are better for finishing ar15 lowers.
What milling machine was used in that setup?

The video showed a drill press being used.
