Designed to fit the Aimpoint ACRO P2, closed emitter red dot sight, the AALG-002 Lens Guard provides an extra layer of protection for your optic. CNC machined from 6061-T6 aluminum, and given a Type III hard coat anodized finish, the Lens Guard attaches to the front of the ACRO P2 with two stainless-steel set screws. This provides stand-off distance between the lens and impact surfaces. The Lens Guard also makes a great ,slide racker,, without leaving hand prints on your P2 front lens. The AALG-002 P2 Lens Guard is designed for optics mounted on a direct cut slide.
