Designed to handle the recoil of your toughest magnum, Burris Pistol Scopes offer fully multi-coated optics for an exceptionally bright view. These variable power pistol scopes have 1/4 MOA windage and elevation adjustments. Waterproof, fogproof and shockproof. Posi-Lock systems replace the springs of a conventional adjustment system with a retractable steel post, to keep the point of aim firmly in place under the harshest recoil. Burris Pistol Scopes are covered by the Burris Forever Warranty.
