I am interested in purchasing a tang sight for my Beretta GoldRush. What size screws do I need to ask the sight maker to send with the sight?

Beretta GoldRush Screws

Both the Beretta GoldRush carbine and rifle use the same size screws. The tang screw is 12-28 TPI UNF. The tang plug screw is 10-32 TPI UNF.
Beretta does not offer a factory tang sight for the GoldRush, nor do we offer longer screws of the correct thread that would be required to mount a tang sight. Both the sight and screws would have to be purchased through an aftermarket sight manufacturer.
