Seekins Precision 0011710295-F Havak PH3 300 PRC 22" 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 purpose-built precision rifle for long-range hunters and competitive shooters who demand speed, reliability, and modularity in one package. Built around Seekins' proprietary quick-change barrel system and new 3-lug bolt design, the PH3 delivers the smoothest action and fastest cycling the company has produced—all without sacrificing accuracy or ease of maintenance. The 22-inch fluted 416R stainless steel barrel is threaded 5/8x24 and finished in black, while the steel receiver wears an integrated 20 MOA Picatinny rail for mounting scopes and accessories. The Urban Shadow camo synthetic stock features an adjustable cheek riser, giving you the perfect sight picture whether you're running a traditional scope setup or exploring newer optic options.

What sets the PH3 apart is its toolless bolt disassembly—you can swap calibers or strip the bolt for cleaning in seconds without breaking out additional tools. The 60-degree bolt throw means faster cycling between shots without the need for a short-action-specific design, and the full-length M-Lok rail integrated into the stock gives you endless mounting flexibility for bipods, slings, and other kit. The Trigger Tech trigger is user-adjustable from 2.5 to 5 pounds, letting you dial in the break that works best for your shooting style.

The 300 PRC chambering delivers flat trajectory and serious downrange energy for extended-range hunting. Seekins engineered the magazine well and action for extended cartridge overall length (COAL) up to 3.9 inches in 300 PRC, meaning you can load long and optimize your ballistics without compromising feeding reliability. Whether you're shooting a backcountry hunt in rough country or running a competition course, the PH3 combines modularity with genuine precision engineering—no hype, just a rifle built to shoot.

Frequently Asked Questions

What makes the quick-change barrel system useful?

The Seekins quick-change barrel system lets you swap to a different caliber or barrel length without gunsmithing. The open-source headspace and tenon specifications mean you can work with compatible barrels from Seekins or other manufacturers who follow the standard. Combined with the toolless bolt disassembly, you can reconfigure the rifle for different hunts or training scenarios in minutes.

Is this rifle compatible with other Seekins stocks or chassis systems?

Yes. The PH3 action is interchangeable with the Seekins M3 Chassis and other compatible stocks, as well as the Seekins Mini Chassis. If you want to change your setup down the road, the action will work with other Seekins platforms.

What does the 20 MOA integrated rail do?

The 20 MOA rail is built into the steel receiver and is angled to give you additional elevation adjustment when mounting a rifle scope. This is especially useful for long-range shooting, where even small adjustments matter. The rail accepts standard Picatinny accessories like scope rings and accessories.

Can I use a suppressor on this rifle?

The barrel is threaded 5/8x24, which is a standard suppressor thread pitch. A compatible suppressor with the same thread pitch will fit, but you'll need to verify compatibility with your specific suppressor manufacturer.
