The Seekins Precision Havak PH3 in 300 PRC is a modern long-range hunting and precision rifle built around Seekins' latest action platform and quick-change barrel system. This 22-inch fluted threaded model comes dressed in Woodland Shadow synthetic stock and delivers the kind of versatility and performance you'd expect from a purpose-built magnum caliber rifle. Whether you're stretching shots on elk or dialing in at the range, the PH3 gives you a smooth, reliable foundation with genuinely useful features—not the usual feature creep that adds cost without value.
The action itself is the real story here. Seekins engineered a 3-lug bolt with a fast 60-degree throw, so you're not wrestling with an oversized handle on every round. Better yet, the bolt disassembles without tools, making cleaning and caliber swaps straightforward in the field. The integrated 20 MOA Picatinny rail is built into the receiver—no rail mounting guesswork—and a full-length M-Lok slot runs along the forend for lights, bags, or whatever you bolt on. The adjustable cheek riser lets you dial in your sight picture without adding shim tape or extra hardware. That 416R stainless steel barrel is fluted to help shed heat and weight, and it's threaded 5/8x24 so you can run a suppressor or muzzle brake that fits your setup. The Trigger Tech trigger breaks between 2.5 and 5 pounds—user adjustable, so you tune it to your style.
The Woodland Shadow composite stock is tough, weather-resistant, and finished in Seekins' subdued camo option. The PH3 action is compatible with Seekins' M3 chassis and Mini Chassis down the road, so if you want to build or reconfigure, you've got that option. The 300 PRC cartridge shines in this platform—Seekins engineered extended cartridge overall length to let you seat 300 PRC rounds out to 3.9 inches, maximizing velocity and performance without jamming into the magazine. This is a rifle that rewards precision-minded hunters and shooters who value clean engineering over gimmicks.

Yes. The Seekins quick-change barrel system and toolless 3-lug bolt make it straightforward to swap to a different caliber without gunsmithing. Seekins publishes open-source headspace and tenon specs so you can source or have a gunsmith turn new barrels.
The PH3 action is compatible with Seekins M3 Chassis and Mini Chassis, so you can upgrade or reconfigure your chassis down the road while keeping the same action.
The 0011710291-F ships as a complete rifle with the 22-inch fluted threaded barrel, Woodland Shadow synthetic stock, adjustable cheek riser, Trigger Tech trigger, and Picatinny/M-Lok rails built in.
The barrel is threaded 5/8x24, a common magnum-class thread pitch. Suppressors and muzzle brakes in that specification will fit, though compatibility depends on the individual device—verify with the manufacturer.
