Rifles

The HK Rifles category is an informational catalog of Heckler & Koch rifle platforms, rimfire models, and upper-receiver-kit references. Use it to distinguish model families, compare general configurations, and locate the appropriate manufacturer documentation before professional inspection or service.

Explore HK rifle categories

• MR Series — MR556 and MR762 family references organized by configuration.
• Rimfire — .22 LR platform references, including HK-branded rimfire configurations.
• Upper Receiver Kits — model-specific kit references separated from complete rifle listings.

Model and configuration identification

Model numbers, barrel-length designations, caliber, configuration, and regulatory classification can distinguish products that appear visually similar. Confirm the complete designation and manufacturer part number before relying on compatibility information. Components and accessories are organized separately in the Rifle Parts catalog. Pistol platforms are listed under HK Pistols.

Safety, regulation, and professional guidance

This catalog is provided for identification and educational reference. Firearms and regulated components must be possessed, transported, stored, and transferred in accordance with applicable federal, state, and local laws. Certain configurations may be subject to additional restrictions. Complete any regulated transfer through the legally required licensed dealer and eligibility process. Follow the manufacturer’s manual and use a qualified gunsmith for inspection, compatibility assessment, or service. Never disable or bypass a firearm safety feature.
