The Seekins Havak PH3 7mm Rem Mag 26″ Mountain Shadow is a production-ready precision rifle built for shooters who demand repeatable sub-MOA performance without the custom-gunsmith price tag. Chambered in 7mm Remington Magnum and wearing a fluted, threaded 26″ barrel, this long-action bolt gun delivers the flat trajectory and retained energy needed for 1,000-yard competition or high-country hunting. The integrated 20 MOA rail and full-length M-LOK forend make mounting optics and bipods a non-issue, while the quick-change barrel system lets you swap calibers in minutes. At $1,849, it’s a serious tool for shooters who value accuracy and modularity.

Key Features
- Quick-Change Barrel System: The 3-lug bolt with 60-degree throw and barrel nut design lets you swap barrels in under 10 minutes without headspace gauges—critical for shooters who want to switch between 7mm Rem Mag and other short-action calibers.
- Integrated 20 MOA Picatinny Rail: Machined directly into the receiver, this rail gives you the elevation range for 1,000-yard shots without needing a 40 MOA base. It’s solid, repeatable, and eliminates a failure point.
- Full-Length M-LOK Forend: The free-floated synthetic stock includes M-LOK slots from receiver to muzzle, so you can mount a bipod, barricade stop, or weights exactly where you need them—no drilling or adhesives.
- TriggerTech Adjustable Trigger: Factory trigger breaks clean at 2.5-3.5 lbs with zero creep. Adjustable pull weight via external screw—no disassembly required.
- Fluted, Threaded Barrel (5/8×24): The 26″ stainless barrel is fluted for reduced weight and faster cooling, and threaded for a suppressor or brake. Muzzle threads are protected by a factory-installed cap.
Who It’s For
This rifle is built for the long-range competitor who wants a production gun that shoots like a custom. If you’re shooting PRS, NRL Hunter, or F-Class production divisions, the Havak PH3 gives you the accuracy and modularity to hang with rifles costing twice as much. It’s also a strong pick for the mountain hunter who needs a lightweight, packable 7mm Rem Mag that can reach out past 800 yards. If you’re a tinkerer who wants to swap barrels between 6.5 Creedmoor and .308 Win (using Seekins’ barrel system), this platform delivers.
Pros & Cons
- Pro: Sub-MOA guarantee out of the box. Per Seekins Precision specs, the Havak PH3 is test-fired and guaranteed to shoot 0.5 MOA or better with quality factory match ammo.
- Pro: Tool-less barrel swap. The 3-lug bolt and barrel nut system let you change calibers in minutes—no gunsmith needed.
- Pro: Lightweight for a 26″ magnum. At ~8.3 lbs, it’s easy to carry in the field or run through a stage.
- Con: The synthetic stock is functional but lacks the adjustability of a chassis—no LOP spacers or ARCA rail included. You’ll need to add them if you want more precision fit.
- Con: The factory trigger is good, but some competition shooters will still swap to a Timney or TriggerTech Diamond for a sub-1-lb break.

What caliber options are available for the Seekins Havak PH3?
The Havak PH3 is available in 6.5 Creedmoor, .308 Winchester, 7mm Remington Magnum, .300 Winchester Magnum, and .300 PRC. The quick-change barrel system lets you swap between these calibers by purchasing a separate barrel assembly—no headspace gauges needed.
Does the Havak PH3 come with a scope or rings?
No, the rifle ships without optics. It includes an integrated 20 MOA Picatinny rail, so you can mount your own scope rings or a one-piece mount. Seekins recommends their own 34mm or 30mm rings for a solid fit.
Can I use this rifle for hunting?
Yes, the 7mm Rem Mag version is ideal for hunting elk, mule deer, and other large game at extended ranges. At ~8.3 lbs with a 26″ barrel, it’s packable for mountain hunts, though you may want to add a suppressor to reduce muzzle blast.
What is the barrel twist rate on the 7mm Rem Mag model?
Per Seekins Precision specs, the 7mm Rem Mag barrel has a 1:9.5″ twist rate, optimized for bullets from 140 to 175 grains. This handles most factory match and hunting loads well.
Is the stock adjustable for length of pull?
The stock has an adjustable cheek riser but does not include length-of-pull spacers. If you need a longer LOP, you’ll need to add a spacer kit or replace the stock with an aftermarket option.
