Seekins Precision 0011710301-F Havak PH3 300 PRC 26" Black Fluted Threaded Barrel, Black Picatinny Rail Steel Receiver, Adj Cheek Riser Urban Shadow Camo Synthetic Stock

The Seekins Precision Havak PH3 in 300 PRC is a modern long-range hunting and precision rifle built for shooters who demand smooth operation, quick barrel changes, and genuine versatility without compromise. This 26-inch fluted, threaded rifle combines Seekins' proven action design with features usually found only in high-end custom builds: a 3-lug bolt with a lightning-fast 60-degree throw, integrated 20 MOA Picatinny rail, full-length M-Lok rail, and an adjustable cheek riser that lets you dial in your sight picture perfectly. The Urban Shadow camo synthetic stock is durable, weather-resistant, and built to take a beating in the field or on the range.

What sets the PH3 apart is the Seekins quick-change barrel system and toolless bolt disassembly—meaning you can swap calibers or deep-clean your action without gunsmithing knowledge or special tools. The 300 PRC chambering delivers serious downrange energy with the room to load long, and the 416R stainless steel barrel is finished with a black flute pattern that reduces weight while maintaining rigidity. The integrated rail system gives you mounting options for glass, night vision, or tactical accessories without adapters or gaps.

The Trigger Tech trigger arrives user-adjustable from 2.5 to 5 pounds, so you can dial it to your preference. Pair that with the rigid steel receiver and carbon composite stock, and you're looking at a rifle that handles recoil predictably and returns to zero shot after shot. This isn't a rifle that asks you to compromise between features and reliability—it delivers both.

Frequently Asked Questions

What's included with the Havak PH3, and is the barrel removable?

The rifle ships complete and ready to mount optics. The barrel is removable via the Seekins quick-change system, allowing you to swap calibers without a gunsmith. You'll need a compatible quick-change barrel and a basic understanding of headspace to change calibers yourself; Seekins publishes open-source headspace and tenon specs to support this.

Can I use the PH3 action with 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 upgrade and customization options down the road.

Is the bolt really toolless to disassemble for cleaning?

Yes. The 3-lug bolt design allows toolless disassembly, so you can deep-clean the action or swap lugs for a magnum or standard bolt without special tools.

Will this rifle work with a suppressor or muzzle brake?

The barrel is threaded 5/8x24, which is the standard thread pitch for suppressors and muzzle devices in magnum rifle calibers. Any suppressor or brake with that thread pattern will fit.
