HK 227901 Three Position Buttstock SP5 Black Polymer Steel

The HK 227901 Three Position Buttstock transforms the SP5 pistol into a more stable and versatile platform. This factory-manufactured stock assembly provides three distinct length-of-pull positions for optimal shooter comfort and tactical flexibility.

What Makes This Different

Unlike aftermarket alternatives, this HK-manufactured buttstock maintains the SP5's original build quality and reliability standards. The three-position telescoping design offers 1.5-inch adjustment range between positions, allowing customization for different shooting scenarios and user preferences. The integrated rubber buttpad reduces felt recoil while the steel reinforcement ensures structural integrity under rapid fire conditions.

Key Features

• Three adjustable length-of-pull positions with secure detent system
• Factory HK construction with polymer body and steel reinforcement
• Integrated rubber buttpad for recoil absorption and shoulder grip
• Quick-detach sling swivel attachment point
• Direct compatibility with HK SP5 pistol and rifle variants
• Matte black finish matches SP5 receiver coating
• Tool-free position adjustment mechanism

The buttstock's polymer construction keeps weight minimal while steel components handle stress points where rapid manipulation occurs. Competition shooters benefit from the consistent cheek weld across all three positions, while tactical applications leverage the compact collapsed position for vehicle operations and extended position for precision engagement. The rubber buttpad maintains positive shoulder contact even with body armor or heavy clothing.
