When it comes to maintaining zero and ensuring that your rifle has the optic-attachment point needed for success in the field, turn to the Geissele Super Precision Aimpoint Pro Series Optic Mount. This high-strength mounting option is a rigid, single-piece design machined from combat-proven 7075-T6 aluminum and is treated with the same Type 3 hard-coat anodized finish the military uses on its equipment. Each mount incorporates a specially designed nut-and-bolt attachment mechanism that clamps down onto your gun with 1,400 pounds of force, ensuring a solid attachment point and maintenance of zero.
