Seekins Precision 0011710303-F Havak PH3 6 Creedmoor 20" Black Fluted Threaded Barrel, Black Picatinny Rail Steel Receiver, Adj Cheek Riser Woodland Shadow Synthetic Stock

The Seekins Precision Havak PH3 in 6 Creedmoor is a modern precision rifle built for hunters and long-range shooters who demand speed, accuracy, and reliability. This rifle combines Seekins' proven quick-change barrel system with a refined action that prioritizes smooth operation and fast cycling—the 3-lug bolt design and 60-degree throw make chambering rounds and working the action feel effortless, whether you're on the range or in the field. The 20-inch fluted stainless barrel is threaded 5/8x24, ready for a suppressor or muzzle brake, and the integrated 20 MOA Picatinny rail gives you a head start when mounting your optic for long-distance shooting.

What sets the PH3 apart is its thoughtful modular design. The adjustable cheek riser lets you dial in your sight picture without shims or tape, and the full-length M-Lok rail gives you endless options for mounting accessories exactly where you need them. The 3-lug bolt is toolless and removable, so you can swap barrels and calibers in the field without gunsmithing, and the bolt itself comes apart just as easily for thorough cleaning. Seekins' open-source headspace and tenon specifications mean you're not locked into proprietary components—this rifle plays well with the Seekins Mini Chassis and other M3-compatible stocks if you want to customize down the road.

Built from 416R stainless steel with a carbon composite Woodland Shadow synthetic stock, the PH3 is finished to handle hard use. The Trigger Tech trigger arrives user-adjustable from 2.5 to 5 pounds, so you can tune it to your preference. This is a serious rifle for serious shooters—dependable, modular, and engineered to keep pace with how you actually hunt and shoot.

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

Yes. The PH3 action is interchangeable with Seekins M3 chassis and stocks, as well as the Seekins Mini Chassis, giving you flexibility to customize your rifle's configuration as needed.

How does the quick-change barrel system work?

The Seekins quick-change barrel system lets you swap barrels and calibers in the field without a gunsmith. The open-source headspace and tenon specifications mean barrels fit precisely and reliably, and you're not locked into proprietary components.

Is the barrel threaded for a suppressor?

Yes. The 20-inch barrel is threaded 5/8x24, which is the standard suppressor thread pattern and will also accommodate most muzzle brakes and flash hiders.
