Universal Telescopic Folding Stock for RPK Kpyk® (Kruk)

The universal telescopic stock RPK Kpyk gives the RPK platform a new level of versatility. Adjustable length, cheek rest height, and buttpad height, combined with a foldable design, secure attachment, and precise fitting. Built on a robust aluminum foundation, it is engineered for demanding use where functionality comes first.

Adaptive design

The stock offers independent adjustment of length, cheek rest height, and buttpad height—tailored to the shooter’s needs. Each adjustment has its own range and locking system, ensuring a stable and repeatable shooting position. Four cheek rest positions and extensive length and buttpad angle options allow precise fine-tuning without compromise.

Durable materials

The load-bearing parts are CNC-milled from aluminum, while the cheek rest is made from reinforced polyamide. This combination provides rigidity, low weight, and long service life. More than 90% of the construction is machined from a solid block, with no thin walls or tolerance-pushed fittings.

Secure folding and carry options

When folded, the stock is held in place by either a magnetic block or an adjustable clamp—both designed to keep it locked when needed. Integrated sling mounts and QD sockets provide multiple carrying options, adaptable to different situations.

Cerakote protection

The surface is treated with Cerakote—a U.S.-made ceramic coating used by leading firearms manufacturers. A thin 50-micron layer protects against chemicals, abrasion, and weather, without affecting function or tolerances.
