Seekins HAVAK PH3 | .300 Win Mag | 22″ Barrel

The Seekins HAVAK PH3 is a feature-rich bolt-action hunting rifle built around a quick-change barrel system and a compact PH3 action intended for magnum cartridges. This configuration is chambered in .300 Winchester Magnum with a 22-inch fluted, threaded barrel and a Seekins carbon-composite Mountain Shadow stock with an adjustable cheek riser. For an optic that pairs well with the PH3 for hunting and extended-range work, consider a Vortex Viper HS-T 4-16×44, a scope commonly available under $1,000 and suitable for both variable-range hunting and precision field shots.
