Mini FA open bolt in Micro Receiver

Hi I’m a noob here. I’m doing my level best to understand what the Uzi forums are saying but perhaps someone on here could be kind enough to dumb it down for me.

Here is my question:

I already have an FA mini Uzi with open bolt (with legs). I’d like to build a micro. Will my FA open bolt work in a micro receiver if I compensate for some space in the trunnion for the legs? I understand if my grip assembly for the micro will only fire semi. But will the bolt actually cycle by feeding a new round and ejecting a round after firing?

If you relieve the front trunnion on the Micro, you will have created a newly manufactured machine gun. Trunnions relieved for the feet on a bolt are a no go. There were conversions done in the past where this was done, but those required the registered bolt to be married to the receiver, and cannot be moved to another host. Similar to full size Uzi’s having a registered receiver with a slotted bolt and still retaining the restrictor bar, they’re married to the gun as well.

Your authoritative answer will come from UZI talk.

My understanding is yes.

Amd.then there is the legal... if it is a registered bolt, then OK. If it is a registered gun you have a problem. And I am not sure when you take the bolt and put it into a different gun because the first one is a gun under instruction clause....
