Seekins HAVAK PH3 | 300 Win Mag | 22in Fluted Threaded | 0011710279-F

The Seekins Precision HAVAK PH3 is a feature-rich bolt-action rifle built around a quick-change barrel system and a three-lug, 60-degree bolt for fast, smooth operation. This configuration includes an integrated 20 MOA Picatinny rail, a full-length M-LOK handguard, and an adjustable cheek riser on the Woodland Shadow synthetic stock. The rifle ships with a 22-inch fluted, threaded barrel and is chambered in .300 Winchester Magnum.

For optics, a mid- to long-range riflescope such as the Vortex Viper PST Gen II 5-25×50 pairs well with this platform and typically retails under $1,000, offering the magnification range and adjustments to match the PH3’s performance envelope.
