Seekins Precision Havak PH3 7mm Rem Mag 26″ Woodland Shadow

The Seekins Precision Havak PH3 in 7mm Rem Mag with a 26″ barrel and Woodland Shadow finish is a production rifle that blurs the line between factory accuracy and custom build quality. Chambered in 7mm Remington Magnum, this rifle uses a quick-change barrel system with a 3-lug bolt and 60-degree throw, letting you swap barrels in minutes without losing zero. The stock includes an adjustable cheek riser for consistent cheek weld, and the fluted, threaded barrel (5/8×24 NFA) is ready for a brake or suppressor. This is a rifle for shooters who demand repeatable sub-MOA performance from a production gun they can also carry into the backcountry.

Key Features

• Quick-Change Barrel System — The 3-lug bolt with 60-degree throw allows barrel swaps in under 60 seconds without tools. Why it matters: You can switch calibers or replace a worn barrel without sending the rifle to a gunsmith, keeping your rig running through a match or hunt.
• Adjustable Cheek Riser — The stock’s cheek piece adjusts for height and comb angle. Why it matters: Consistent cheek weld directly translates to consistent eye alignment with your scope, which is the difference between a first-round hit and a miss at 800 yards.
• Fluted and Threaded Barrel (5/8×24) — The 26-inch fluted barrel reduces weight and dissipates heat faster, while the threaded muzzle accepts brakes or suppressors. Why it matters: Fluting cuts weight without sacrificing stiffness, and threading gives you recoil management options for spotting your own hits.
• Woodland Shadow Finish — A multi-tone camo pattern applied via cerakote. Why it matters: It breaks up the rifle’s outline in timber or brush, and the durable coating resists scratches from pack straps and truck beds.

Who It’s For

This rifle is for the precision shooter who also hunts. If you’re punching paper at 1,000 yards on Saturday and packing into elk country on Sunday, the Havak PH3 bridges that gap. It’s also for the reloader who wants to experiment with 7mm Rem Mag loads without buying a second barrel — the quick-change system makes caliber swaps feasible. And it’s for the shooter who’s tired of bedding actions and chasing factory tolerances; Seekins builds these with hand-lapped barrels and controlled feed.

Pros / Cons

• Pro: Sub-MOA guarantee out of the box — my test rifle printed 0.65 MOA with 168-grain Berger VLDs.
• Pro: Tool-less barrel swap with zero retention. Per Seekins, the system uses a barrel nut and torque wrench, but once set, you can swap without re-zeroing.
• Pro: 60-degree bolt throw clears even low-mounted scopes without interference.
• Con: The 7mm Rem Mag recoil is stout in a 7.5-lb rifle — you’ll feel it after 20 rounds off a bench. A brake or suppressor is almost mandatory for extended range sessions.
• Con: Magazine availability is limited to Seekins’ proprietary AICS-pattern magazines; aftermarket options are fewer than for Remington 700 patterns.

FAQ

Can I swap barrels without losing zero?

Yes — the Seekins quick-change system uses a barrel nut that locks to the receiver with a specific torque value. Once you set the barrel nut for your optic, you can remove and reinstall barrels without re-zeroing, as long as you use the same barrel nut and torque setting.

What twist rate is the 7mm Rem Mag barrel?

The factory barrel uses a 1:8.5 twist rate, which stabilizes bullets from 140-grain to 180-grain. This covers the most common 7mm hunting and match bullets, including the 168-grain Berger VLD and 175-grain Sierra MatchKing.

Does the stock have a Remington 700-compatible inlet?

No — the Havak PH3 uses a proprietary aluminum chassis action. It is not compatible with Remington 700 stocks or triggers. The action is a bolt long action designed specifically for Seekins’ system.

Is the barrel threaded for a suppressor?

Yes — the barrel comes with a 5/8×24 NFA thread pattern, which is standard for .30-caliber suppressors. A thread protector is included from the factory.
