BudsGunShop.com - Optics on Mossberg 930

YES, all Mossberg 930 receivers are drilled and tapped to accept optic. I hope this helps

Joe, yes Sir. All 930 receivers are drilled and tapped, so the addition or removal of an optic sight is a snap. It's a nice touch. The guns also come with what Mossberg calls the "Stock Drop Spacer" system that allows the user to easily and quickly alter the drop and/or cast of the buttstock to fit the shooter and sight system.
