## Description

Bobro Engineering Dual Lever Precision Optic Mount 30mm Rings Black B10-300-300. The base has an extension that allows proper eye relief even when using a non-monolithic rail. It is designed so that the base allows the use of a folding back up iron sight (BUIS). The structure is designed for maximum strength and utilizes larger fasteners than our standard lineup. This mount is engineered to handle heavy optics and high recoil forces. Specifications for Bobro Engineering Dual Lever Precision Optic Mount w/30mm Rings: Manufacturer: Bobro Engineering Height: 1.5 in Fabric/Material: 6061-T6 Aluminum Color: Black Distance Between Rings: 2.975 in Tube Diameter: 30 mm Length: 2 in Weight: 9.5 oz Width: 0.99 in Finish: Type 3 Hard coat black anodizing Features of Bobro Engineering Dual Lever Precision Optic Mount w/30mm Rings: The Precision Optic Mount features the Patented BLAC lever system which was designed around the following parameters: Must be compatible with any 1913 Specification Rail to include systems that are out of specification (within reason) and this includes Weaver rails. Must be completely tool and user adjustable free It needs to be 100percent self contained and mate securely to any rail without the user having to tailor the pressure/engagement position. Must lock with enough pressure to positively attach any device or optical instrument to a rail without movement static or dynamic forces not withstanding. The rail must not experience any deformation due to user error This must include synthetic (plastic/polymer/composite) rail systems. Auto Index capability The device must also index parallel to the bore The unit must always repeat the forward shift (recoil forces direction of influence) not only to maximize zero repeatability but to take this step of installation out of the users initial mounting sequence Index must be redundant. Unit must not shoot loose due to improper mounting or a mechanical bottoming out. The system must incorprate a safety that pr
