Design & operating context

Design and role

Heckler & Koch’s family page groups several versions under shared technical information and warns that dimensions and weights vary with configuration. Accessories and magazine state therefore matter.

How to read the evidence

A nominal calibre identifies a cartridge family, not weapon effectiveness. Future mass and length claims need the exact model, stock position and included accessories; generic family values are held back.
