Purchased this to add to my vector full size uzi. Its a well thought out design, and allows the use of a red dot on a firearm that was never designed to have an optic. The installation was pretty simple, use the included template, drill the appropriate holes to allow the plate to protrude through the cover, add loctite to the bolts threads and tighten it down. Works well many micro dots. I have not had a chance to fire it yet, but I'm sure it will not disappoint. Would recommend.
