If you have a registered receiver UZI the s/n on the transfer form should relect the original serial number given to the firearm by IMI/Group Ind. or whoever the manuf. was. This should also have the blocking bar removed from the receiver so that military bolts will drop right in.
Don't forget the 41AE this cartridge makes the ballistics of the 45ACP into a girl's gun. Only a barrel and magazine change is required here.
Also for 45 conversions a M-10 45 mag housing can be welded onto the UZI SMG lower so that the UZI can accept 30rnd grease gun magazines.
