Grand Power Stribog Side-Folding SBR Stock

The Grand Power Stribog Side-Folding SBR Stock is the factory stock for SBR-registered or rifle-length Stribog builds. It uses a steel hinge with a positive locking detent that holds the stock open in the firing position and folded against the receiver during transport. Length of pull is fixed (not adjustable), but the height and cheek weld are tuned for the Stribog's bore axis from the factory.

This is a true rifle stock, not a brace. NFA rules apply: the Stribog must be configured as an SBR with an approved Form 1 or Form 4, or built up as a 16-inch barrel rifle. Installing this stock on a pistol-configured Stribog without registration is a federal violation. Most owners running this stock have already registered the Stribog as an SBR, which removes the brace-stock distinction entirely.

For pistol-configured Stribogs, the factory PDW Collapsible Stock (separate product, $299.99) provides similar folding behavior with brace-legal classification. For 1913 brace-pattern installs, pair the HBI 1913 Adapter with a Strike Industries FSA or SBA3/SBA4 instead. OpticsPlanet stocks at $99.99 (SKU GPSP9A1FFS).
