PLEASE READ FOR SELECTION INFO *IF DRILLING AND TAPPING YOUR GUN, MOUNT WILL COME WITH #8-40 SCREWS UNLESS YOU NEED #6-48 or M4x.7 Please send an inquiry if you have questions* Our mounts work on guns that come pre-drilled and tapped from the factory, as well as guns that you plan to drill and tap. The dropdown menu allows you to select the model number for your gun so that we send the correct profile and screw types. If your gun is not drilled and tapped you can select that option from the dropdown list. If you do not see your pre-drilled and tapped gun on the chart please send us an inquiry so we can let you know when they will be available. For optic selection, due to the extra recoil lugs that protrude into the screw holes in the optic, we will send mounting screws. Selecting your exact optic ensures we provide you the screw head type and length needed.
