Overview
The Kinetic Development Group SRX6 is the 6-inch M-LOK receiver extension for the Grand Power Stribog. It bolts to the front of the upper receiver via a dedicated mounting block plus four upper-receiver fasteners, six fastening points total, which makes the lockup substantially more rigid than typical drop-in handguard extensions. The result is a stable platform for forward grips, lights, lasers, and suppressor shrouding.
The extension is machined from 6061-T6 aluminum and finished in Type III hardcoat or Cerakote. M-LOK slots run along the body, and the 1.72-inch internal diameter accommodates many 9mm suppressors. KDG requires the rail to be used with its SMX3 or SMX6, a suppressor, or another device that carries the muzzle beyond the rail, and specifically excludes the B&T VERS36 Ti.
KDG also makes the SRX3.25 MkII for shooters who want forward real estate without the full-length extension. The current black SRX6 is SKU STR5-MK2-020; FDE sibling STR5-MK2-120 is selected on the same product page. This catalog entry remains limited to Stribog SP9 hosts with M-LOK receivers.
