Can You Sell a Homebuilt Gun Without a Serial Number

posted Tuesday, June 23rd 2015 at 7:27 AM by

Completed 80% Lower Receivers

Looks like the BATFE updated their website, and in the process didn't forward any of the links from their old content to the new URL format, bad web development!

But I digress.

I wanted to take this as an opportunity to update my links, as well as expand on some of the topics discussed in my earlier post about the legalities of building your own firearms. Namely, can you sell a home built firearm without a serial number?

922(r) Compliance Calculator

posted Friday, June 12th 2015 at 10:16 AM by

922(r) Compliance

There are a few 922(r) compliance worksheets floating around on the internet, most are really good but quite a few are dated, not functional, and as I discovered when I started my Galil build, inaccurate. I wanted to provide a more up to date resource, and here it is!

How to Fix AK47 Trigger Slap

posted Monday, March 30th 2015 at 8:01 AM by

AK47 Trigger Slap Animation

Trigger slap is a minor, yet common problem shooters of the AKM pattern rifle may experience. This post will get into detail about what trigger slap is, and the specific point during cycling that it happens. I've also provided instructions on how to fix it, as well as discussing a few myths circulating online about trigger slap.

    Adam,
    Excellent write-up on this subject. I have observed another problem with the enlarged Bulgarian style trigger guard rivet and the new ALG AKT triggers. After about 1000 to 3000 rounds, a fellow rifle classmate had his ALG trigger disconnector split in half (bisecting the tail and the hook). The enlarged rivet was nearly beaten down half way with a outline of the tail. This happened once at 3000 rounds and then again at 1000 rounds. So, the englarged rivet puts a lot of additional stress on the disconnector. In addition, the shortened travel of the ALG trigger allows even less room for disconnector travel. I believe the solution to this would be simply to grind off the ALG disconnector tail. Or, harder disconnector spring? Thoughts? Obviously ALG/Geissle will have to rethink think their disconnector design as most Arsenal AK's have the enlarged rivet. This is evident as even my Egyptian Maadi build has a small dent in the standard sized rivet with the ALG disconnector.

      Good points Chang, thanks for the feedback. Very interesting to hear about the failures and at what round count they occurred. The solution you've suggested will work for semi-auto AKs, but the select fire version would still need the disconnector tail, so removing that wouldn't be the solution for AKs as a whole.

      The problem happens when the bottom of the disconnector impacts the trigger, and pushes the trigger forward. The solution would be to remove material from either of those surfaces until the disconnector stops pushing the trigger forward.

    Thanks for your explanation, I replaced original trigger on my Vepr .308 with ALG-Ak and it was a lot of work with my dremel, after testing rifle at my range I found that I got pretty nesty slop, I removed additional metal as you suggested today and will try again soon. Vepr 308 needs a lot of dremeling but ALG is still much better than one installed by Fime.

Is it Cheaper to Buy or Build an AK47

posted Friday, March 13th 2015 at 9:56 AM by

Cost of Building an AK47

The topic of home-building AK47 rifles comes up every now and then on various firearms boards, which usually leads to questions about the tools involved and the price to build.

The great question, however, is it cheaper to build an AK47 or just buy one off the shelf? I've been home-building firearms for a few years and the answer is simple, it depends...

    You didn't figure cost of your time. We build AK types to sell as a manufacturing FFL. We have all the tools for press builds you mentioned plus other specialty tools, jigs, kiln for heat treatment etc. And all the tools for custom finishing. To take the typical cut up AK parts kit in a bag to a fully finished ready to sell rifle has at least 30 man hours. I estimate that to be our average start to finish. There is no way we can sell rifles for the same or less than what it costs to buy. However there are people who want something different than what you can find in a store and will pay.

      Good point. The article was geared toward hobbyists. Typically they're more concerned with their own craftsmanship and personal satisfaction than they are with time.

    First off, your costs to build your own ak are a joke! If a person has any mechanical ability he can figure out how to build the project without all of the way over priced tools on the market! Doesn't take a genius to build your own "toth" barrel install and removal tool with scrap metal readily available from scrap yards or job sights everywhere. Allthread you can buy or I can bring it home from work in construction. Rivets can be set by hand with a ball peen hammer and patience. You just have to be willing to cut and drill and file or whatever it takes to make your own tools. They don't have to be store bought and they don't have to be pretty, just have to work. When I looked up some of the build tools online I had to laugh at the prices, sorry but I'll make my own and save my money. Common sense and know-how can save you a ton of money if you're willing to get dirty, most people aren't.

I did a couple posts for GoPro picatinny rail mounts as well as GoPro mounts for hunting rifles. In the final post of the series, I'll take them to the range and see how they hold up under recoil.

So, grab you eye and ear protection and and make the jump for the full report.

GoPro Weapon Mount Review Part II: Non-Railed Mounts

In trying to find reviews of GoPro mounts for rifles, I was disappointed that nothing I found online seemed to talk about how to mount them, or if it did, it didn't show any example photos of what the mount looked like, and what the images looked like when mounted.

Just like my earlier review for GoPro mounts for rifles with rails, this review will covers a couple different mounting options if you've got a rifle without rails. Oh yeah, and lots of pictures.

How to Zero the M16A1 Series Rifle

How to Zero the M16A1

Now that I've got my M16A1 clone put together from the kit and my 80% lower, and the rear sight fixed, its time to take it to the range and get it sighted in. In order to do that I'll have to zero the sights. Finding an old copy of Army STP 21-1-SMCT from 1987 proved to be a bit difficult, so I've transcribed a copy here for future reference.

M16A1 broken rear sight

So I took my recently finished M16A1 clone to the range to be zeroed, and I could not for the life of me get the group to move left or right. After a bit of searching, I discovered the rear sight drum was broken. Note the hairline crack in the photo.

Crap. Now what?
