Reduce glare, forward reflections, and accidental damage to your scope's objective lens using Kahles' Sunshade for 50mm or 56mm Riflescopes. This 2.0"-long (50mm objective) or 2.5"-long (56mm objective) sunshade will easily thread on either the 50mm or 56mm objectives of your Kahles riflescope and match your optic's overall durability with its aluminum construction.
