Seekins Precision 0011710223-F Havak PH3 6.5 Creedmoor 20" Black Fluted Threaded Barrel, Black Picatinny Rail Steel Receiver, Adj Cheek Riser Urban Shadow Synthetic Stock

The Seekins Precision Havak PH3 in 6.5 Creedmoor is a purpose-built precision rifle for hunters and long-range shooters who demand a smooth action, field-swappable barrels, and a modern tactical chassis platform. Built on Seekins' latest 3-lug bolt design with a fast 60-degree throw, this rifle combines a 20-inch fluted stainless steel barrel with an adjustable cheek riser stock, giving you the ergonomic control and accuracy foundation serious shooters expect.

The PH3 action is engineered around Seekins' quick-change barrel system with open-source headspace and tenon specs—meaning you can swap barrels in the field without a gunsmith, and the bolt disassembles toollessly for cleaning and maintenance. The integrated 20 MOA Picatinny rail sits on a steel receiver and pairs with full-length M-Lok for mounting optics, lights, or accessories exactly where you need them. The 5/8×24 threaded muzzle is ready for a suppressor or brake. All of that bolts into a composite Urban Shadow stock with an adjustable comb, letting you dial in your cheek weld for consistent scope alignment shot after shot.

This is a rifle built for hunters planning long-range 6.5 Creedmoor work, whether you're glassing from a high ridge or punching steel at distance. The modular Seekins platform means you're not locked into a single barrel or caliber—you're buying into a system. The TriggerTech user-adjustable trigger spans 2.5 to 5 pounds, so you can tune the break to your preference.
