Reptilia Sdl Mnt 1301/A300 509T

The Reptilia SDL mount for the Holosun HE509T brings a purpose-built, low-profile optic solution to Beretta 1301 and A300 shotgun platforms. Machined from billet 7075-T6 aluminum and finished to military hard-coat anodize standards, this saddle mount positions your red dot as low as possible over the receiver while maintaining a true co-witness with factory iron sights—a critical advantage when you need both precision aiming and fast backup sight acquisition in the field or on the range.

Whether you're running a tactical shotgun, hunting with buckshot, or competing in 3-gun, a low-mounted optic that doesn't block your irons is foundational to reliable performance. Reptilia's engineering keeps the HE509T footprint precisely aligned with your Beretta's native sight plane, eliminating the height-over-bore guesswork that plagues hastily adapted mounts. The billet construction and hardened finish mean this mount will handle the recoil and weather exposure that shotgun use demands without flex or corrosion.

Made in the USA and built to exacting tolerances, this mount rewards the shooter who values durability and co-witness capability over trendy multi-optic solutions. If your Beretta 1301 or A300 is going to wear an HE509T, this is the mount that does it right.
