Seekins Precision 0011710277-F Havak PH3 7mm BC 22" Black Fluted Threaded Barrel, Black Picatinny Rail Steel Receiver, Adj Cheek Riser Urban Shadow Synthetic Stock

The Seekins Precision Havak PH3 7mm BC rifle combines precision engineering with practical modularity for hunters and long-range shooters who demand both performance and versatility. This 22-inch fluted, threaded-barrel rifle ships with an Urban Shadow synthetic stock and a steel receiver topped with integrated Picatinny rail—a complete, field-ready package that rewards serious accuracy work from the moment you open the box.

Built around Seekins' modern 3-lug bolt design with a 60-degree throw, the PH3 action cycles faster and smoother than traditional designs while remaining drop-in compatible with Seekins M3 chassis and stock systems. The standout feature here is the quick-change barrel system: you can swap calibers without gunsmithing, using nothing but hand tools. That open-source headspace and tenon spec means you're not locked into proprietary parts—a real advantage if you want to experiment with different loads or calibers down the road. Toolless bolt disassembly makes field cleaning and maintenance genuinely hassle-free.

The 416R stainless steel barrel arrives fluted and threaded at 5/8x24, ready for a suppressor or muzzle brake. The adjustable cheek riser lets you dial in your head position for scope height and sight picture without shimming or tape. You get a full-length M-Lok rail underneath for accessories, and the integrated 20 MOA Picatinny top rail gives you serious elevation adjustment room for extended-distance work. The user-adjustable Trigger Tech trigger breaks between 2.5 and 5 pounds—you tune it to your preference. Urban Shadow is a clean, modern finish that works equally well in field or range scenarios.

This is a rifle built by shooters for shooters: no marketing fluff, just thoughtful design choices that make real sense when you're behind the gun or swapping barrels at the bench.

Frequently Asked Questions

Can I use a Seekins Havak PH3 action in other chassis or stocks?

Yes. The PH3 action is compatible with Seekins M3 chassis and stock systems, and with Seekins mini chassis, giving you flexibility to build or reconfigure your rifle later.

What calibers does the quick-change barrel system support?

The quick-change barrel system is open-source, meaning you can source barrels in various calibers as long as they meet Seekins' published headspace and tenon specifications. The extended cartridge overall length (COAL) accommodates up to 3.14 inches for 6.5 PRC and 3.9 inches for 300 PRC and 300 Win Mag among others.

Do I need tools to change barrels or disassemble the bolt?

The bolt disassembly is completely toolless—no wrenches or screwdrivers needed for cleaning or maintenance. Barrel changes require hand tools but no gunsmithing or specialized equipment.

Is this rifle suppressor-ready?

Yes. The barrel is threaded 5/8x24, which is standard for centerfire rifle suppressors. You can mount a compatible suppressor or muzzle brake directly to the barrel.
