The 12-inch HK417 is the compact designated marksman variant designed for close-quarters battle where a full-length DMR would be unwieldy. The short barrel sacrifices significant 7.62x51mm velocity — roughly 300 fps compared to the 20-inch — but remains effective within typical urban engagement distances. Used by special operations units that need 7.62 capability in a package no larger than an M4. Type: Rifle Action: Semi-Automatic Caliber: 7.62x51mm Capacity: 10 Year introduced: 2006, Germany Weight: 87.2 oz Overall length: 30.5" Status: Active Military use: Yes Intended use: military, cqb, dmr
