Kinetic Development Group 3.25" MkII Ultimate Bog Bundle Stribog SP9 M-LOK Rail Extension - Black Cerakote

The Kinetic Development Group 3.25" MkII Ultimate Bog Bundle is a matched accessory package designed for the Stribog SP9 family of firearms equipped with M-LOK receivers (SP9, SP9A1, and SP9A3). This coordinated kit pairs a 3.25" SRX3 MkII M-LOK rail extension, an SMX3 muzzle extension, and an enhanced charging handle, giving shooters a single-purchase upgrade for grip, control, and accessory mounting.

At the heart of the bundle is the SRX3 MkII rail, machined from 6061 T6 aircraft-grade aluminum and finished in rugged Black Cerakote for excellent corrosion and wear resistance. The rail adds 3.25 inches of M-LOK-compatible handguard surface for mounting weapon lights, lasers, vertical grips, and bipods, and weighs 4.02 oz on its own. The included SMX3 muzzle extension extends the front of the handguard for a more secure support-hand grip and improved recoil management, while the upgraded charging handle provides better leverage for faster, more positive manipulations.

All three components share a matched Black Cerakote finish for a cohesive, factory-coordinated look. The complete bundle weighs 6.2 oz installed and is a direct-fit upgrade for the Stribog SP9 platform.
