The M-BRACE Scope Mount is an evolution of the M10 Scope Rings, designed with engineering precision, unlike simple gadgets.
There may be interference with the bolt handle on a 90 degree bolt rotation action if mounted on the far aft recoil slot; this can be resolved by moving the mount forward.
Specific torque specifications are provided for the scope clamp, rail mount screws (55 in-lbs), and the bubble level screw (30 in-lbs).
