Altius Clamp Ring for Anschutz Front Sight.  This is a replacement part for the 2-piece system (clamp ring plus rubber O-ring) currently used with the Anschutz front sight hood.  Designed and Made in Montana, this part creates a true 'round' front sight profile without having to rely on the O-ring that can easily become damaged or lost.  NEW for 2020:  Face of Clamp Ring is now grooved to reduce glare.
