Rs Reg 1913 Long Picatinny Rail Modular Upper Receiver

The RS Regulate 1913 Long Picatinny Rail is a modular upper receiver mounting solution built for AK shooters who demand flexibility and precision. This system solves a core AK platform problem: getting your optic positioned exactly where you need it, in the footprint and offset that works for your rifle and your shooting style. Whether you're setting up a dedicated DMR, a home-defense carbine, or a precision rifle, the modular rail system lets you dial in the perfect sight picture without compromise.

The design centers on customization. You get three different lower mount options—a full-length lower rail, a forward rail, and a rear rail—so you can position your optic front-to-back and left-to-right across the receiver. That means you're not stuck with one mounting location; you're building the setup that fits your gun and your grip. The system is machined from aircraft-grade 6061-T6 aluminum and kept lightweight, so adding glass doesn't slow you down. A practical bonus: on most AK variants, you can strip the rifle down without removing your mounted optic, keeping your zero intact and speeding up maintenance.

The redesigned thumb-lever lock is a confidence builder. It holds zero even after you remove and remount your optic repeatedly, and the staking provision adds security for hard-use roles. Co-witness mounting is supported, giving you backup sighting and flexibility in your sight picture. Two versions cover the most common micro optics: the AKML for Aimpoint T-1 and H-1, and the AKOG for Trijicon ACOG systems.

Can I remove my optic without losing zero?

The redesigned thumb-lever lock is engineered to retain zero even after repeated optic removal and reinstallation, so you can confidently take your optic off and put it back on without walking your groups.

Will I have to remove my optic to field-strip my rifle?

On most AK variants, no. This mount allows field stripping without optic removal, keeping your zero intact and making routine maintenance faster.

Two versions are available: the AKML for Aimpoint T-1 and H-1 Micro Red Dots, and the AKOG for Trijicon ACOG sight systems.
