Seekins Precision
The Seekins Precision Havak Pro Hunter Ph3 Mountain in 308 Win with a 16-inch barrel is a modernized bolt-action rifle built for hunters and long-range shooters who demand both precision and practicality in the field. This isn't a rifle designed by committee—it's engineered around real-world use: quick caliber changes, rock-solid accuracy, and enough modularity to adapt to your setup without a gunsmith. The PH3 combines Seekins' proven 3-lug bolt design with a host of features that make it equally at home on a mountainside or at the range.
The action itself is the star here. Its 60-degree bolt throw is among the fastest on the market, and the toolless, removable bolt design means you can swap between standard and magnum bolt heads without tools—handy for shooters who want to experiment with different calibers or maintain their rifle in the field. The quick-change barrel system uses open-source headspace and tenon specifications, so you're not locked into proprietary components. The 416R stainless steel barrel is threaded 5/8x24 and built for accuracy and durability.
On the tactical side, the rifle ships with an integrated 20 MOA Picatinny rail for long-range optics and a full-length M-Lok rail for accessories. The adjustable cheek riser lets you dial in proper scope cheek weld without shimming or aftermarket parts. Seekins PH3 carbon composite stock handles recoil management and keeps weight down. The Trigger Tech trigger breaks between 2.5 and 5 pounds, user-adjustable to your preference. Available in the Mountain Shadow finish shown here, this rifle is built to last—Seekins backs it with a no-questions-asked lifetime warranty.
