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 makes mounting optics to your AK-47 pattern extremely easy. This 2nd generation AK-307M lower scope rail is one of the most precise, rugged, and lightest weight you can find on the market. However, the real claim to fame is the unique titanium-based locking system that is extremely low profile and attaches directly to the side mount on your 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 allows for the widest range of adjustment, so you can get proper eye relief with your scope. It is made from 6061-T6 aluminum and the modular design allows you to mount your optic directly over bore. 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:
  • Yugo
  • Yugoslavian
  • Serb
  • Serbian
  • PAP
  • NPAP
  • OPAP
  • Zastava
  • M21

The AK-307M front biased lower rail weighs just 3.37 ounces and is compatible with Yugo M21 and PAP pattern side 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. The unique locking system is machined to have the tightest tolerances possible so that every time it gets re-attached, your scope will be in the exact same position and you won’t need to mess with your zero.

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 rail systems to fully personalize your setup.

Always good timely service and quality products here.Keep up the good work

Need more products like this!


Amazing workmanship. Fit my O-pap perfectly. If you want to put a scope on your Yugo AK, this is the only right way to do it. Don't forget the AKR upper mount!

Great AK Mount for my Yugo N-Pap


Crazy fast shipping. I had tracking info an hour or two after submitting the order.I love this side mount. I had tried the eBay knockoff of the midwest mount with the dremel mod but it sat too high and was not directly over the bore axis. This along with the AKMD mount is perfect for my Bushnell TRS-25.

Quality doesn't come cheap


Excellent quality scope mount. With the built in adjustability this mount lines up perfectly and is light weight but strong. Wish I had just gotten this scope mount first.



I know we all have seen videos and pics of this mount but it even looks better ones you hold it and mount it on your rifle. I'm very satisfy with this mount , it's worth the extra money, do your self the favor and save up the $$$ and get it. The machining on the mount if outstanding the way it mounts and works/holds is great . I have no doubt that it will last a live time.

just what the mil-dot ordered


I purchased the RS AK-307 for my Zastava M77.This rail is a perfect fit for the Yugoslavian/Zastava optics rail, because RS designed it for these rifles. Primary Arms ships fast and has great customer service. In the end I could not be happier.

Great mount for AK


I put this on a Pap M77 PS and the mount slides on closer to the rear sight, which gives good eye relief for mounting a scope. It locks on securely and awesome for an AK.

Looks great.


I really like this rail. I researched for a long time and this product was recommended over and over. It fit perfectly. The only snag was getting the adjustment bolt to turn. After a little frustration I realized the spring for the pushdown was getting caught in the bolt thread. After rotating it 90 degrees it worked perfectly. I only write this so that anyone else with this issue might realize it sooner than I did. It is beautiful on my Yugo AK.

The ONLY way to run an ACOG...


I was looking for a way to use an acog on my npap, this mount offered the perfect solution. Keeps the optic as lowas possible, fit and finish it top notch, and the size and weight of the mount is minimal.

fits like a glove...


i'd give it 5 stars but the price is high. as far as the product, it fits like a glove. very well made and very light...
