The Seekins HAVAK Element M3 .300 Win Mag 22″ Mountain Shadow is a purpose-built mountain hunting rifle that shaves ounces without cutting corners on precision. This is a fully modular, ultra-lightweight build using Seekins’ patent-pending quick-change barrel collar and a three-lug, 60-degree bolt for fast, smooth cycling in the field. The carbon-wrapped 416R stainless barrel pairs with the Seekins PH3 carbon composite stock and adjustable cheek riser for a stable, lightweight platform that carries like a dream. Threaded muzzle and included hunter-style brake round out a rig that’s ready to hunt from ridge to valley. Per manufacturer specs, this rifle weighs under 7 pounds bare, making it a serious contender for backcountry hunters who demand sub-MOA accuracy.

Key Features
- Quick-Change Barrel Collar: Patent-pending design lets you swap barrels in minutes without a gunsmith—ideal for caliber changes or replacing a shot-out tube in the field.
