Franklin Armory M4-HTF XTD R3 | .350 Legend | 16″

The Franklin Armory M4-HTF XTD R3 is a modern semi-automatic rifle built around a 16″ M4 contour barrel chambered in .350 Legend. It ships with a 15″ free‑float style handguard, Aura XTD muzzle device, B5 Bravo furniture, and an optic-ready upper for straightforward optics mounting. The rifle’s features suit medium-range accuracy needs and stateside hunting or range training where .350 Legend is appropriate.

Suggested optic: a variable 1–6x close-to-mid-range riflescope such as the Vortex Viper PST Gen II 1-6x (well under $1,000) pairs well with this platform for fast target acquisition and practical precision at typical engagement distances.

Applications: hunting with straight-wall cartridges where permitted, and precision-focused range training or tactical-style target work.
