Seekins Precision 0011710269-F Havak PH3 7mm PRC 26" Black Fluted Threaded Barrel, Black Picatinny Rail Steel Receiver, Adj Cheek Riser Mountain Shadow Synthetic Stock

The Seekins Precision Havak PH3 7mm PRC is a modern mountain rifle built for hunters and long-range shooters who demand speed, reliability, and real versatility. This 26-inch rifle combines Seekins' proven quick-change barrel system with a smooth 3-lug bolt action and a fluted, threaded barrel in 416R stainless steel, giving you a capable field gun that handles both close work and extended-range hunting. The Mountain Shadow synthetic stock pairs clean aesthetics with practical functionality, while the adjustable cheek riser ensures repeatable scope alignment in the field.

What sets the PH3 apart is its modular architecture. The 3-lug bolt design strips down without tools for cleaning or barrel swaps, letting you adapt the rifle to different calibers using Seekins' open-source headspace and tenon specs. The integrated 20 MOA Picatinny rail comes ready for glass, and the full-length M-Lok rail gives you clean attachment points for sling hardware, tactical accessories, or minimalist setups. A user-adjustable Trigger Tech trigger (2.5–5 lbs) rounds out a platform that rewards both precision shooters and hunters who need reliability in variable conditions.

The 7mm PRC chambering is built for modern ammunition: the extended cartridge overall length (COAL) lets you load long for maximum velocity and ballistic performance without compromising magazine function. Paired with a muzzle brake-ready 5/8x24 threaded muzzle, the PH3 is engineered for shooters serious about downrange capability. Seekins' reputation for durability and modularity—backed by their no-questions-asked lifetime warranty—makes this a rifle you'll trust for seasons to come.
