Heckler & Koch SP5K Folding Stock Black

The Heckler & Koch SP5K folding stock is a factory-original German-engineered accessory that transforms how your SP5K handles in tight spaces and dynamic shooting scenarios. Built from durable black polymer, this stock replaces the factory butt cap and folds to the right side of the firearm, giving you a genuinely compact platform when you need it. Whether you're working in confined quarters, wearing body armor that demands a different cheek weld geometry, or just prefer a shorter sight picture, this folding buttstock with integrated butt pad delivers the ergonomic flexibility that the SP5K platform deserves.

H&K designed this stock with the realities of professional and civilian operators in mind. Smaller-stature shooters and those geared up for duty often find that a fixed stock doesn't play well with plate carriers, helmets, or body armor. The fold-right design keeps the stock out of the way when collapsed and snaps into firing position with the stability you expect from H&K engineering. The included butt pad provides a solid shouldering surface and helps manage recoil impulse during extended range sessions or tactical training.

Installation is straightforward—no gunsmithing required. This is a direct replacement for the factory butt cap on SP5K models, so you're getting authentic H&K parts compatibility and the reliability that comes with OEM fit and finish. If you run an SP5K 9mm, 10mm, or .40 S&W pistol or rifle variant and want genuine folding-stock capability without the guesswork, this is the upgrade that makes sense.
