Seekins Precision PH3 Havak .300 Winchester Magnum with a 26″ fluted threaded barrel, black Picatinny rail steel receiver, adjustable cheek riser, and Woodland Shadow synthetic stock.
The Seekins Precision Havak PH3 in .300 Winchester Magnum is a bolt-action, long-action rifle built for accurate long-range performance and repeatable barrel changes. It uses a Seekins quick-change barrel system with a three-lug bolt and a 60-degree throw, and includes toolless bolt disassembly for caliber changes and cleaning. The rifle features an integrated 20 MOA Picatinny rail and a full-length M-LOK for accessory mounting, paired with an adjustable cheek piece and a Woodland Shadow synthetic stock. For optics, a Vortex Viper PST Gen II 5-25×50 is a practical pairing for this platform and provides the magnification and reticle clarity appropriate for .300 Win Mag precision work without exceeding typical mid-range optics budgets.
