BudsGunShop.com - Red dot

Bryan, you will have to purchase an adapter plate separately depending on Wich red dot you choose. Without the adapter you cant add a red dot. I would contact beretta at +1-800-237-3882 or email them at (techsupport@berettausa.com) to find out Wich adapter fits your needs. Hope this helps.

Bryan, depends on the needed Plate. The 92X RDO has Five adapter plates for red dots available, that can be purchased separately on the Beretta e-store.
