so im finally building my uzi from a parts kit that i have. i have to buy a semi bolt and i think a new sear. could someone tell me what sear i have and if it will work with the new semi auto bolt.
Yes, it's one of the newer style SMG sears. The SMG sear doesn't have the proper angle to match up with a semi-auto striker, so you should replace it with a proper semi-auto sear.
