The Seekins Precision Havak PH3 in .308 Winchester is a precision rifle built for shooters who demand a smooth action, reliable performance, and genuine long-range capability. This 20-inch barreled rifle combines Seekins' reputation for quality machining with a modern, modular design that works hard whether you're dialing in at the bench, hunting at distance, or running drills on steel. The Woodland Shadow synthetic stock gives it a practical finish that blends function and form—no unnecessary frills, just a rifle engineered to deliver.
At the heart of the PH3 is Seekins' 3-lug bolt design paired with a 60-degree throw, offering one of the fastest and smoothest actions on the market. The quick-change barrel system uses open-source headspace and tenon specs, so swapping calibers is toolless and straightforward—pull the bolt, swap the barrel, and you're ready to go. The integrated 20 MOA Picatinny rail is built into the receiver, eliminating the need for a separate base and giving you a solid foundation for optics and accessories. Full-length M-Lok rail runs the length of the forearm for mounting lights, grips, bipods, or whatever your mission demands.
The 416R stainless steel barrel is fluted to shed weight without compromising rigidity, and it threads at 5/8x24 for suppressors or muzzle devices. The adjustable cheek riser lets you dial in your sight picture to the scope, a feature that matters more the longer your shots get. Trigger Tech delivers a user-adjustable pull between 2.5 and 5 pounds—crisp and consistent. The PH3 action is compatible with Seekins' M3 chassis and the Mini Chassis, so if you decide to go modular down the road, your investment is protected.
