The Seekins Precision Havak PH3 in .308 Winchester is a modern precision rifle purpose-built for long-range hunting and target shooting. This 20-inch barreled .308 Win rifle combines a short-throw action, modular quick-change barrel system, and a purpose-designed chassis stock into a platform that rewards both accuracy and efficiency. Whether you're setting up a dedicated long-range hunting rifle or a competition-grade platform, the PH3 gives you real control over your setup without compromising reliability or ease of maintenance.
The Havak PH3's action is the heart of the system: a 3-lug bolt design with a 60-degree throw makes cycling fast and smooth, and the toolless removable bolt design means you can swap barrels or field-strip for cleaning without hunting for tools. The integrated 20 MOA Picatinny rail comes pre-mounted on the receiver, giving you a solid optic mounting platform right out of the box, while the full-length M-Lok rail on the stock opens up endless mounting options for accessories. The 416R stainless steel barrel is fluted to shed weight without sacrificing stiffness, threaded 5/8x24 for suppressors or brakes, and chambered in .308 Winchester—a proven cartridge for hunting and precision shooting at distance.
The Urban Shadow synthetic stock features an adjustable cheek riser so you can dial in your cheek weld for your optic setup, and the rifle ships with a TriggerTech user-adjustable trigger tuned between 2.5 and 5 pounds. Seekins backs every PH3 with their no-questions-asked lifetime warranty, so you're covered for the life of the rifle. If you ever want to explore the quick-change barrel system's versatility, Seekins has published open-source headspace and tenon specifications so you can source or commission barrels in other calibers.
