Bobro Dual Lever Precision Optic Mount 30mm 0 MOA

The Precision Optic Mount features the Patented [US Patent 8,567,105] BLAC(TM) 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 100% 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
