The AK-307MS full length lower rail weighs just 3.5 ounces and is compatible with Zastava and other AK rifles with a Zastava style side rail. 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 to provide customers with a solid and dependable way to customize their AK pattern rifles with any optics they want: from ACOGs, to red dots, to full 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.
