Heckler & Koch Rifle Accessories for Sale

Heckler & Koch GmbH of Germany treats Rifle Accessories as platform support for its rifles, maintaining an official lineup that grew from free‑floating quad‑rail handguards, sights, and magazines for HK416/HK417 and MR‑series rifles to Slim Line HKey options and, by the mid‑2020s, M‑LOK handguards. HK’s Rifle Accessories are OEM, platform‑specific parts built around its mounting standards, featuring free‑floating rail systems designed for tool‑less removal with repeatable zero, extensive STANAG 4694 Picatinny top rails, the proprietary HKey interface on Slim Line handguards, and newer M‑LOK choices that emphasize fit, durability, and consistency on service‑grade platforms.
