Note: This is only the lower rail. The upper optic mount must be additionally purchased to use your optic.

The RS Regulate modular scope mounting system for AK-47 rifle is one of the best ways to mount an optic. Most AK mounts are do not provide a solid lock up which can result in losing zero after just a couple of shots. This 2nd generation AK-309M lower scope rail is one of the most precise, rugged, and lightest weight on the market, and it attaches directly to the proprietary side rail on your C39V2. What makes this optic mount unique is the titanium-based locking system that is extremely low profile and attaches directly to the receiver. Once this full length lower rail is locked down, it isn’t going anywhere ensuring that your rifle stays zeroed with your favorite optic. The full-length rail option gives you the largest amount of positioning, so you can truly customize how you want your optic set up. It is made from 6061-T6 aluminum and the modular design allows you to mount your optic directly over bore and adjust for proper eye relief. All you need is an upper optic mount compatible with your favorite red dot or scope and you are ready to head to the range.

Full Compatibility List:
  • C39V2
  • RAS47

The AK-309M full length lower rail weighs just 3.37 ounces and is compatible with Century Arms rifles with factory side mount rails. With the AK-300 line of lower rail mounts, you can easily remove your optic for storage and retain zero the next time you attach it at the range. This rock-solid RS Regulate mount system is top of the line when it comes to attaching modern optics to the classic AK-47 pattern of rifle.

RS Regulate was built on the idea of providing customers with a solid and dependable way to customize their AK pattern rifles with any optics they want from an ACOG to full on rifle scopes. After years of testing and researching, they came up with the AK-300 modular mounting system which allows a huge variety of customization in terms of optics positioning. This two-piece design allows you to choose the lower and upper picatinny rail systems to fully personalize your setup.

Recommeneds RS Side Mount!


I paired this mount with the ak-300 modular side mount for a red dot configuration. Fit and finish is really nice, has a solid clamp and always holds zero. I have been satisfied with this product for 12 months. I stand by RS quality products.
