The Seekins Precision Havak PH3 in 300 Win Mag is a precision rifle engineered for hunters and long-range shooters who demand a modern action with genuine versatility. This rifle combines a smooth 3-lug bolt design with a 60-degree throw, integrated 20 MOA Picatinny rail, and Seekins' quick-change barrel system—all housed in a Woodland Shadow synthetic stock with an adjustable cheek riser for consistent scope mounting and shooter comfort. The 22-inch fluted 416R stainless barrel is threaded 5/8x24 and built to tight tolerances for inherent accuracy, while the steel receiver and full-length M-Lok rail give you room to customize with accessories that matter to you.
What sets the PH3 apart is its emphasis on user control and modularity. The 3-lug bolt disassembles without tools for cleaning and maintenance, and the quick-change barrel system accepts Seekins barrels for fast caliber swaps—no gunsmith required. The action is cross-compatible with Seekins M3 chassis and stocks, so your investment in the platform grows over time. The trigger is user-adjustable from 2.5 to 5 pounds, letting you dial in the break you prefer. For serious distance shooting or hunting where you're covering ground, the PH3 delivers the kind of reliability and precision that comes from purposeful design, not marketing hype.
Whether you're chasing elk in high country or stretching your shots on the range, the Havak PH3 gives you the foundation to shoot farther and straighter—and the flexibility to adapt it to your needs without replacing the whole rifle.
| Caliber | 300 Win Mag |
| Action | Seekins Havak PH3 (3-lug, 60-degree bolt throw) |
| Barrel | 22-inch fluted 416R stainless steel |
| Muzzle Threading | 5/8x24 |
| Picatinny Rail | Integrated 20 MOA |

Yes. The Seekins quick-change barrel system and toolless bolt design let you swap barrels without a gunsmith. The bolt disassembles by hand for cleaning and for magnum or standard caliber changes. Seekins also publishes open-source headspace and tenon specifications so you can work with other gunsmiths if needed.
The integrated 20 MOA Picatinny rail accepts standard Picatinny-mount rings and optics. The 20 MOA inclination is built into the action, so you get additional elevation travel for long-range shooting without adding a specialty mount.
The Havak PH3 action is compatible with Seekins M3 chassis and stocks, and with Seekins Mini Chassis, giving you upgrade options if you want to change your setup later.
The full-length integrated M-Lok rail accommodates standard M-Lok accessories—bipods, rail panels, lights, and other gear. The rifle leaves plenty of real estate for mounting what you need without removing components.
