Can this mount to a standard picatinny rail?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on March 01, 2021

The 509T will come with an RMR adapter plate so that you can install the adapter plate to any standard Trijicon RMR mount or slide and then the 509T will clamp to that adapter plate once it has been installed to the mount/slide. This includes a large majority of Trijicon RMR Picatinny mounts.

Will this work with a FN 509T?

A
Answered by BMF18, guest, from WA, United States, on October 10, 2020

I mounted mine today on my FN 509 Tactical. I had to mount the RMR Holosun 509T plate on top of a RMR plate. This seems the only option at this point. The red dot sits high and your rear suppressor sight is out of play. Until a plate is created I don’t see any other way for it to fit. Better than nothing for right now and it shot spot on.

Justin Mackrella, member, from PA, United States, asked on January 25, 2020

can this optic be used on a rifle as well? I'm looking for a good micro red dot for an AK.

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on March 01, 2021

Yes, you will just want to get an RMR picatinny mount for your AK and then you can install the adapter plate included with the 509T and from there the 509T will clamp to that adapter plate.

Q
ANGELO RUSSELL, guest, from NJ, United States, asked on January 25, 2020

What type of mount will it using ?

A
Answered by John Smith, member, from CA, United States, on August 02, 2020

It will have a proprietary mount. Because it’s not an open emitter there is no way to screw in screws from top down like on a RMR. The mount will be more similar to a picatinny mount with a side screw to tighten. Confirmed it won’t be the same as the Aimpoint ACRO footprint. It will be unique. Hopefully they will have an adapter plate to fit RMR cut slides, but that means having the sight ride higher than I would like. Best of luck

Charmane, guest, from TX, United States, asked on February 07, 2022

Will this fit a walther Q5 match?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on February 09, 2022

Yes, the Holosun HE509T Reflex Optical Red Dot Sight comes with an RMR footprint adapter. So you would need to get the RMR mounting plate from Walther to mount the Holosun HE509T Reflex Optical Red Dot Sight to a Walther Q5 Macth.
