Kinetic Development Group STR5-MK2-020 SRX6 MK2 Stribog Rail Extension Black Aluminum Compatible w/ Stribog SP9 Models w/ MLOK Receivers

The Kinetic Development Group SRX6 MK2 Stribog rail extension is a 6-inch forend upgrade built for shooters running Stribog SP9 platforms with M-LOK receivers. If you've found the stock grip too short, cramped your hand position, or run out of real estate for mounting lights and accessories, this aluminum extension solves those problems in one piece. It threads directly onto compatible Stribog SP9 builds, giving you both the reach and mounting versatility that modern PCC shooters expect.

The SRX6 MK2 is machined from 6061-T6 aircraft-grade aluminum and finished in black Cerakote, so it'll hold up to hard use without adding unnecessary weight. M-LOK slots run the full length of the rail, meaning you can attach lights, vertical grips, laser modules, or sling hardware exactly where you need them. The contoured profile is designed around shooter ergonomics—it won't feel like a tube bolted to your gun; instead, it naturally fills your hand and keeps your grip stable through rapid fire or longer range sessions.

Because the extension increases forend length, you get better sight radius if you're running iron sights, and suppressors mount cleanly with plenty of standoff and ventilation to keep things cool. This isn't a lightweight tacticool add-on; it's a functional upgrade for anyone serious about their Stribog setup.
