The RS Regulate AK-306M fits the side rail on Yugo and Serbian pattern rifles, including the Zastava M21, PAP, NPAP and OPAP, and must be paired up with an “upper” mount for your particular optic (sold separately). The RS AK-300 system pairs a “lower” mount that attaches to the side rail of a Kalashnikov pattern rifle with an “upper” mount that interfaces with a specific optic model, making it possible to securely and precisely mount popular AR-15 tactical optics on an AK platform rifle.
This lower is constructed from lightweight yet strong 6061 T6 aluminum, finished with a durable matte black hardcoat anodized finish. The RS AK-306M series lowers utilize a titanium-based, low-profile lock system that does not protrude from the mount or into the trigger guard area. The front biased rail option is lighter than the full length option and allows you to place your optic as far forward as possible. All necessary hardware is included for easy setup.
Once matched with an optic-specific upper mount, it allows for adjustments in both the over-bore height and front-to-back position of the optic, ensuring perfect eye relief and a comfortable head position. RS lowers are the strongest, lightest, and thinnest side mounts in the world.
