Modern shotguns have become increasingly capable platforms, and red dot optics have become a practical addition for everything from defensive use to competition and hunting. The challenge is mounting that optic securely without adding unnecessary height, weight, or complexity.
That is where the Reptilia SADDLE™ line comes in.
Reptilia SADDLE mounts are purpose-built optic mounting solutions designed around specific shotgun platforms and optic footprints. Rather than relying on a universal rail and stacking multiple mounting interfaces, each SADDLE is designed to put the optic as low and close to the shotgun as possible.
The result is a cleaner, more streamlined setup with a natural sight picture and a mounting solution built specifically for the firearm and optic it supports.
The current SADDLE lineup covers four configurations: two purpose-built for the Beretta® 1301™ and A300™ shotgun family and two designed to adapt the ELCAN® SpecterDR to modern red dot optics, but we are focusing on the Shotguns at the moment. We will save the ELCAN SADDLES for another write up, now back to the boom sticks.
One Name, Different Solutions
The SADDLE name describes a simple idea: create a dedicated interface between a specific platform and optic, eliminating unnecessary height and extra mounting hardware.
For the Beretta shotgun mounts, that means a direct, low-profile solution designed around the 1301 and A300 receiver. Both shotgun SADDLE mounts are machined from billet 7075-T6 aluminum, hardcoat anodized to MIL-STD Type III specifications, weigh 23 grams, and are designed to provide a low co-witness with the factory Beretta iron sights.
SADDLE for Beretta 1301 & A300 and Aimpoint® ACRO or Steiner Optics® MPS™

For shooters running an enclosed-emitter optic with the ACRO footprint, this is the dedicated solution.
The mount is compatible with the Aimpoint ACRO P-1, P-2, and C-2, as well as the Steiner Optics MPS. It uses the screws supplied with the Beretta 1301 or A300 and positions the optic as low as possible on the shotgun.
The result is a streamlined optic setup without adding unnecessary bulk or height.
SADDLE for Beretta 1301 & A300 and Holosun® 509T™

The 509T version brings the same low-profile approach to optics utilizing the Holosun HE509T footprint.
Compatible optics include the Holosun HS509T and the Holosun/Primary Arms® HE509-RD ACSS Vulcan Reticle. Like the ACRO version, it is machined from billet 7075-T6 aluminum, hardcoat anodized, weighs 23 grams, and is designed to maintain a low co-witness with the factory iron sights.
For 1301 and A300 owners, the choice comes down to optic footprint. The mounting philosophy remains the same: put the optic where it needs to be and remove everything that does not need to be there.
Choosing the Right SADDLE
The right SADDLE depends on two things: your platform and your optic.
Running a Beretta 1301 or A300?
- Choose the ACRO / MPS SADDLE for Aimpoint ACRO or Steiner MPS optics.
- Choose the 509T SADDLE for Holosun 509T-footprint optics.
- There are 12G and 20G options, specifically for the A300.
Built for the Platform, Not Adapted to It

The entire SADDLE line follows the same principle that drives Reptilia’s mounting systems: a mount should be designed around the equipment it connects.
That means platform-specific geometry, minimal added height, and a direct interface wherever possible.
Adding a red dot to a Beretta 1301 or A300 shotgun, the SADDLE lineup offers dedicated solutions built to keep the setup low, simple, and purpose-built.
