The Beretta 1301 / A300 RDO Adapter Type D is an authentic, factory-original optic mounting platform engineered to provide a rock-solid link between your shotgun receiver and your mini reflex sight. It does not feature an optical magnification range, as it functions strictly as a physical CNC-machined metal base rather than a magnifying target lens system. This heavy-duty component adds exceptional value to your defensive or competition shotgun by dropping your FastFire or Docter footprint optic down to a low-profile saddle depth, drastically accelerating target acquisition speeds over traditional rail-height options. Machined from high-strength aircraft aluminum alloy and treated with an anti-glare matte black protective coat, the kit comes complete with the necessary Torx receiver mounting hardware for straightforward installation. Swapping out your factory rail for this direct-mount plate eliminates stacking tolerances, ensuring your zero remains completely unyielding under the punishing recoil impulses of heavy 12-gauge duty or match payloads.
