The Seekins Havak PH3 .308 Win 20 in. Urban Shadow is a modular, field-ready precision bolt-action rifle built for shooters who demand repeatable accuracy in harsh environments. Chambered in .308 / 7.62 NATO, this configuration pairs a 20-inch fluted, threaded barrel with an integrated 20 MOA Picatinny rail and full-length M-LOK for modern accessory mounting. The PH3 features a three-lug bolt with a 60-degree throw and Seekins’ quick-change barrel system, enabling caliber swaps and simplified maintenance. An Urban Shadow carbon composite stock with adjustable cheek riser and a TriggerTech user-adjustable trigger complete the package.

Key Features
- Quick-Change Barrel System — Why it matters: swap calibers or replace barrels in under 10 minutes with a single tool, extending rifle life and mission flexibility.
- Three-Lug Bolt with 60-Degree Throw — Why it matters: faster cycling from prone or barricade positions without losing cheek weld, critical for follow-up shots.
- Integrated 20 MOA Picatinny Rail — Why it matters: mounts optics directly without aftermarket bases, giving you full elevation travel for long-range dialing.
- TriggerTech User-Adjustable Trigger — Why it matters: pull weight adjusts from 2.5 to 5 lbs with zero creep, letting you tune for precision or speed.
- Full-Length M-LOK Handguard — Why it matters: mount bipods, lights, or IR lasers anywhere along the forend without extra rails.
Who It’s For
Law enforcement precision rifle squads, military scout/sniper teams, and serious long-range shooters who need a lightweight, modular platform that holds sub-MOA accuracy in field conditions. This is not a budget hunting rifle — it’s a tool for those who shoot for a living or compete at the highest levels.
