AHG Rear Sight BlinderThe ahg-universal eyeshade is simply attached to the existing iris disc or rear sight disc. Two plastic discs, transparent and black, (supplied) can be swung out in order to cover the non-aiming eye. This will help in relaxing the aiming eye. This shield can be used by left or right hand shooters. Contact us at 70822-33324, if the product is in pre-order status.
