Asura Dynamics have released an AluminiumB13 Side Mount Rail for a whole variety of AK brands out there!
These Include:
-GHK (2011),
-LCT,
-Marui,
-E&L,
-CYMA
This will blend very well with the Lower Handguard as this combination will make your AK incredibly tacticool. This will allow you to mount sights on top so I have a feeling that this will be a very popular product as a lot of people like to modernize their AKs.
