Yugo AK underfolder build
I picked up a couple of Yugo underfolder receivers and kits, and have been trying to figure out the easiest way to convert them to CA legal. I think I may have come up with something.
To keep them semiauto, I'd have to pin the stock to keep it at least 30", so it doesn't get classified as an AW based on length. I would also have to either remove the pistol grip, or pin the magazine. The only way I can see keeping these features, is to make it not semiauto. I was trying to come up with all sorts of ways to remove the gas piston, then I realized the obvious. The Yugo has a gas shutoff valve that is attached to the grenade sight. If I unscrew that valve, and replace it with one that is plugged, that should make it no longer fire as semi-auto, correct? If so, I could build this with the folding stock intact, as well as the pistol grip and detachable magazine. The only other things I would need to change out are the 922 compliance parts. |

I just fixed the magazine - cut out the top, rear of the magazine release bit on the trigger guard assembly. Put a nut behind the magazine release, and then bottom out the release with a bolt that runs through the nut.
I didn't know the Yugos had a gas cutoff screw, do you know the specs to it? I'dbe interested in changing mine out. I bought a Red Star Arms adjustable 2-stage trigger/hammer/sear for my AK and it is incredible. I highly recommend it. |

I wasn't planning on getting a gunsmith to do it though. If I can't find an aluminum spacer the right size, I'll make one on the lathe at work. |

I will have to try this out at the range to make sure it works. But I managed to find an almost perfect replacement for the gas cutoff valve. The diameter is correct, the shoulder of it is just a hair too long, but that can be corrected with another washer.

I permanently fixed one of mine to single shot, I filled the gas block with high temp silver solder, plugging the hole. I also then cut down the gas piston so it wouldnt allow it to get pushed back if the plug were to come loose.
The kit was a very poor polish kit $70 so I didnt waste to much modifing it. The gas shutoff on the Yugo seems to sound OK but I would be concerned LEO/DoJ would say it would be to easy/tempting to open it up and have a illegal AK. Similar to the mag release, gas system should require tools or be permanent. Just my .02 on this one. |

IF they list them(and I think they will), and IF the receiver you picked up happens to be one of the ones listed, and IF they don't try to pull that Cat. 4 crap like in that memo, then you could build them up to AW status after you registered it. Anything else, and you are taking your chances. But these have been all hashed over many times in the legal forum, with nothing but a bunch of tin foil hat conspiracy theories to show as the result. Personally, since the mod I am doing is fairly easy, and I am comfortable with how compliant it is, I will finish building mine up. |

In the case of the Yugo, I would try to buy a spare gas valve, and weld the hole shut ont he spare part, or weld your original- it can be drilled should you ever leave the state- just write down the hole diameter. No need to do anything more than you legally need to do. it's tougher on regular AK's since there's not an easily modifiable part, i.e. the gas selector. -Dave |

If I were any of you, I would not have the parts to make a complete AR/AK in illegal configuration. Removing the piston? Get rid of it. Altering a part? Make sure you have no others. Even if uninstalled, do NOT have the parts to build one into a full rifle.
If you think I am over doing it, buy a AR pistol barrel without an AR pistol...

WHY? DOJ has already SPECIFICALLY said that if you remove a threaded barrel from a pistol (say USP tactical, P22), and store it next to the pistol, it's not an AW unless IT IS INSTALLED. PERIOD. It don't get clearer than that.
Your AR pistol upper is wholly irrelevant. It regards FEDERAL law, were constructivve possession applies with machine guns and SBR's. State AW law does not have constructive possession. Period. This has already been discussed- time for the search function, and less fearmongering. -Dave Quote:

Leaving them in a box 35 miles away in a room I don't have a key to, should satisfy the federal guidelines.
