At HK Parts, we offer a wide range of high-quality Heckler and Koch accessories and components for your favorite firearms. Whether you are upgrading a Heckler and Koch pistol or rifle, or building with parts kits, we have you covered. Explore top-rated components for VP9, USP, P30, MP5, MP5K, G36, HK416, and more. From triggers, barrels, and grips to magazines, stocks, and sights, find the parts you need to enhance performance, reliability, and function.

Popular upgrades include match triggers, threaded barrels, compensators, optic plates, and extended magazines. Rifle owners often add enhanced stocks, forearms, and ambidextrous controls.
MP5 and MP5K kits are top sellers, giving shooters authentic components for iconic builds. G36 and HK416 kits are also highly sought after by collectors and professionals alike.
HKP offers the world’s largest H&K-focused catalog, with better availability, faster fulfillment, and expert support compared to general retailers.
