Description
The RS Regulate AKMR is the piece that finally gets a modern micro red dot riding low and clean on an AK. It's built as the optic-specific upper for the AK-300 Modular Side Mount System, machined from lightweight aluminum and cut for the Trijicon RMR footprint. Bolt an RMR-pattern optic to it and the sight sits down close to the dust cover, giving you a slim profile and quick, natural target acquisition instead of a red dot perched way up high.
What the AKMR Upper Actually Bolts To
This is an upper mount only, so it needs an RS Regulate lower to do its job. The lower clamps directly to your rifle's factory side rail and stays put, while the AKMR snaps onto it and holds the optic. That two-piece setup is the whole point of the AK-300 system. Pick the lower that matches your side rail (something like the AK-303M full-length lower is a popular general-purpose choice for standard AKM-pattern rails), lock it down once, and you can swap uppers down the road without ever disturbing your rifle's rail interface.
Optics That Fit the AKMR Trijicon RMR Mount
The AKMR is cut for the RMR footprint, so it covers a wide range of popular micro red dots. Trijicon RMR and RMR Type 2, the Trijicon SRO, the Holosun 507 series, and other reflex sights sharing that same base all drop right on. If you've already got an RMR-pattern dot in your kit, this mount lets you run it on the AK without hunting down a proprietary solution.
Why AK Guys Trust the RS Regulate System
RS Regulate has been building these mounts since the early days of the AK optics resurgence, and the reputation is earned. The design lets you fine-tune both over-bore and front-to-back placement, so your dot ends up exactly where your eye wants it. It's light, it's machined well, and once it's locked to the lower it holds zero and shrugs off recoil. For a lot of AK owners, this modular approach is the cleanest way to run a modern optic on a classic platform.

Frequently Asked Questions
Does the AKMR Trijicon RMR upper come with a lower mount?
No, the AKMR is the upper optic mount only. It has to be paired with a separate RS Regulate AK-300 lower that clamps to your rifle's side rail. Once you have the correct lower for your platform, the AKMR attaches to it and holds your optic.
Which optics fit the RS Regulate AKMR RMR mount?
It's machined for the Trijicon RMR footprint, so it accepts the RMR and RMR Type 2, the Trijicon SRO, the Holosun 507 series, and other red dots that share that same base pattern. If your dot uses an RMR footprint, it should mount up cleanly.
How do I know which RS Regulate lower I need?
The lower is chosen based on your rifle's side rail rather than the optic. For standard AKM-pattern rails found on many Russian, Bulgarian, and similar rifles, a general-purpose lower like the AK-303M full-length is a common pick. Match the lower to your rail, then run the AKMR on top for your RMR-pattern dot.
Will the AKMR hold zero on an AK?
Yes. Once the lower is properly locked to the side rail and the AKMR is seated on it, the interface stays tight and repeatable through recoil. The modular design also lets you fine-tune over-bore and front-to-back position so your dot ends up right where your eye wants it.
