Features

The KDG MK2 Stribog Bundle – 6" FDE is a complete performance upgrade package designed to enhance ergonomics, control, and modularity on the Grand Power Stribog SP9 platform. This Flat Dark Earth configuration combines Kinetic Development Group’s key components into a cohesive system built for both function and aesthetics. At the core of the bundle is the SRX6 MK2 6-inch M-LOK rail extension, which significantly increases forward grip space and provides expanded mounting options for lights, lasers, and other accessories. Its contoured profile improves handling and stability, especially during rapid fire or extended shooting sessions. Paired with the rail is the SMX6 muzzle extension, designed to redirect blast forward and away from the shooter’s support hand—enhancing safety and comfort when running extended handguards or suppressors. The bundle also includes an oversized knurled charging handle, delivering improved grip and faster, more reliable manipulation under stress. Constructed from 6061-T6 aluminum (rail) and durable steel components (muzzle extension and charging handle) with a Cerakote FDE finish, the system maintains a lightweight yet rugged profile. Designed as a drop-in upgrade for Stribog SP9 models with M-LOK receivers, this bundle delivers a balanced solution that improves handling, customization, and overall shooting performance.
