So after building a fullsize uzi pistol on a McKay enterprises receiver and bolt, I haven't had the chance to file my SBR paperwork yet, But I am loving this uzi build more than the 9mm AR SBR it replaced, It suppresses very very well, and even as a large pistol it is still pretty easy to shoot, I modified a QD sling cup to mount on the rear of the receiver where the stock would mount. It shoots very well, and is reliable, But I have check the clearance on the top cover to make sure its in spec..However when I take the top cover off it tends to cut me, So I figure I have a few sharp edges to file down. I really want one of the Rail systems for it so I can mount a light to it.
I am surprised at the ease and simplicity of the UZI when assembling it, Only really needed a Screwdriver to tighten the grips down.
So, who else here has an UZI in any form, post a pic.
