The new KDG Modular Optic Mount is based off the proven Sidelok family of quick detach optic mounts, and features the same user-friendly, tool less design. KDG set out to design a Sidelok mount for all common, tube-style optics that will offer more user-configurable options than what is currently available from competing QD mounts. The mount is offered with a user removable cantilever bar, in which the rings securely mount. This bar runs parallel to the weapon's bore, and is ideal for all semi and fully automatic carbines, rifles and DM style firearms. The matched front and rear rings are CNC machined, and wire EDM cut to be as precisely concentric as possible. The upper and lower ring remain matched for the duration of its production, and feature witness marks for assembly in the form of recessed dots. This allows the user to match the proper ring to its base, and ensure the mount is as truly aligned as possible. The rings themselves can be adjusted forward or back to the user's preference, to avoid interference with large front objective bells, turret adjustment knobs, and rear magnification adjustment collars. The rings themselves bolt into a track system to facilitate this adjustment. The same track system allows the user to purchase and install separate rings in the future, should they decide to change to an optic with a larger or smaller diameter tube. This feature will save the shooter or organization money, as the majority of cost is in the base of the unit.
