Uzi parts kit build questions

So Uzi part kits are pretty cheap now, so besides a semi auto reciever and a barrel is anything else needed? Also does anyone know of gunsmiths who you can ship parts to and get the gun built and how much it might run? Since I suspect Uzi carbines vs the micro uzi pistol fall under 922r, what is the parts count?

This would be something spread over a few months so the fact it may be near the same as a centurion or other uzi clone out there so it isn't a big deal since I couldn't afford to get at once anyway.

^ True Uzi's semi - or full auto are NFA due to the open bolt. There have been some clones that dont fire from open bolt but I doubt the parts kit would work.

In that case what did Action Arms do from the mid to late 1980s when open bolts were pretty much banned and before the George Bush Gun Ban? Obviously they were changed, but still used Israeli military parts.

I also saw that RTG oe RTR arms (forget the name) sells what it calls No Dak Completion kits which seens to indicate that it can be used with some parts of the parts kits.

I've seen several older semi uzi's and mac 10's and 11's in my lgs over the years that fired from an open bolt. My lgs is not a class iii dealer nor do they deal with any such things, therefore I'm guessing the older ones are grandfathered in. But you can't make new ones?

ATF made them NFA items in the early 80's (81-82ish.) there were tons imported prior and the semis were grandfathered.. Sheer numbers are also why they are the cheapest entry to full auto..

I'm guessing they changed the bolt assemblies to a closed system. (?) i have no experience with them so I'm not sure.

You can buy surplus parts kits that contain the F/A parts for a number of weapons now-a-days. I wouldn't advise actually installing them thou..

Good luck

The early semi MACs were open bolt, then later changed to closed bolt. The semi UZIs were always closed bolt. Differences are: the bolt assembly, barrel, selector, fire control/grip housing, and assembly pins among others. The semi receiver has a blocking bar welded into the right receiver wall behing the ejection port to prevent insertion of a full auto open bolt. Semi bolts have a slot to pass over that bar. The fire control/grip housing has a small blocking bar welded into the front of the housing to prevent the selector from moving forward of the semi position. The selector itself is slightly different. The rear of the barrel is turned down to slip inside a feed ramp unit that is not present on the full auto models. The assembly pin and holes are a different size on the semi and full auto models. Completion kits are available from several sources to finish partially formed/finished receivers. They do not include the bolt and striker assemblies. Some folks modify the full auto bolts and either by a striker or fab one. Modifying the bolt would be the hardest part. The full auto bolt has a fixed firing pin that is simply a raised tit in the center of the bolt face. The semi bolt has a clearance hole all the way through for the striker mounted firing pin. The bolt is made from some tough heat-treated metal and is difficult to machine. Better to find a semi bolt and striker assembly.
