The ArmorMason Dual Offset Rail Interface Mount Base is an aluminum rail accessory that adds two angled Picatinny mounting surfaces to a standard 20mm rail. It is designed to expand usable rail space on a handguard or upper receiver without modification to the host rifle.

Versatile applications:
Common applications include offsetting a magnifier or red dot for better eye relief, mounting a weapon light at an angle that keeps the tail switch within thumb reach, running a laser unit on the opposite offset rail to keep both devices off the top rail, or staging multiple accessories on a build with limited rail length. The two angled surfaces are symmetrical, so the same mount works equally well for right and left-handed shooters and supports balanced left-right accessory placement on a single rifle.

Construction and finish:
Machined from aluminum alloy and finished in matte black anodized coating. The lightweight body does not add unwanted weight to the rifle, preserving balance and handling speed. The anodized layer is intended for sustained outdoor use.

Installation:
The mount slides directly onto an exposed section of Picatinny rail. The two top screws compress the clamp around the rail when tightened, providing a fixed grip that does not shift under recoil or hard handling. The mount can be removed or repositioned using the included hex key. Permanent modification to the rifle is not required.
