Uzi Permanent Stock Bushing
The permanent stock bushing is used to convert the Quick Disconnect stock mounting hardware so it may be permanently mounted to a semi-auto carbine. Using the same bolt as the permanent collapsible stock, the bushing replaces the original bushing and does not protrude from the back plate allowing the mounting hardware to sit flush. CNC machined from steel and finished in manganese phosphate "parkerizing." NOTE: Original stock mounting hardware must have the button machined to flush and a hole drilled in its place for the bolt. Also the stock must have a relief drilled for the bolt head.
