The Reptilia SADDLE is a receiver-mounted optic mount for the Beretta 1301 and A300 shotguns, cut for the Holosun 509T footprint and low enough for a co-witness with the factory Beretta iron sights.
Same shotguns as the ACRO saddle, entirely different footprint. The 509T is an enclosed optic with its own mounting pattern, and this is the saddle machined for it.
Reptilia calls it the lowest possible mounting solution for a miniature red dot using the Holosun HE509T footprint, allowing a low co-witness with the factory Beretta irons. It is machined from billet 7075-T6 aluminum in MIL-STD Type III hardcoat anodizing and weighs 0.8 oz (23 g).
Compatible optics are the Holosun HS509T and the Holosun/Primary Arms HE509-RD with the ACSS Vulcan reticle — both the same enclosed housing, different reticles. A sealed emitter is a sensible choice on a shotgun that works in wet conditions, because nothing outside the housing can dim the dot. Made in the USA.
Key Features
- 509T footprint: Cut for the Holosun HS509T and HE509-RD ACSS Vulcan, not the ACRO pattern
- Mounts to the receiver: No rail section and no riser, so the optic sits as low as the shotgun allows
- Low co-witness: The factory Beretta iron sights remain visible through the optic window
- 0.8 oz (23 g): Billet 7075-T6 aluminum in MIL-STD Type III hardcoat anodizing
- Enclosed emitter: A sealed optic on a shotgun that lives outdoors, with nothing to foul the LED
Compatibility & Fitment
Fits the Beretta 1301 and A300 line of shotguns, taking the Holosun HS509T and the Holosun/Primary Arms HE509-RD with the ACSS Vulcan reticle. This is the 509T version. If your optic is an Aimpoint ACRO or a Steiner MPS, you need the SADDLE for ACRO and MPS instead — same shotguns, different footprint, and the two will not swap. It will not fit any other shotgun.

Frequently Asked Questions
How is this different from the other Beretta saddle?
The footprint. This one is cut for the Holosun 509T's enclosed mounting pattern; the other SADDLE is cut for the Aimpoint ACRO and Steiner MPS pattern. Both fit the same Beretta 1301 and A300 receivers, and neither will accept the other's optic. Choose by the optic you already own.
Which Holosun models fit?
The HS509T, and the Holosun/Primary Arms HE509-RD with the ACSS Vulcan reticle. Those two share the same enclosed housing and mounting pattern; only the reticle differs. A 507 or 508 uses the Trijicon RMR footprint and will not fit this saddle.
Will the factory sights still work?
Yes. Reptilia designed the saddle to sit as low as the receiver allows precisely so the factory Beretta irons stay in view through the optic window. That is what a low co-witness means: two sighting systems in one picture, without adding a riser.
Does it need a rail?
No, and adding one would defeat the purpose. The saddle mounts to the receiver itself. Any rail-plus-mount arrangement puts the optic higher and takes the irons out of the picture.
