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.

Popular upgrades include match triggers, threaded barrels, compensators, optic plates, and extended magazines. Rifle owners often add enhanced stocks, forearms, and ambidextrous controls.
