Seekins HAVAK PH3 300 Win Mag 22″ Mountain Shadow
About this product
The Seekins HAVAK PH3 300 Win Mag 22″ Mountain Shadow is a purpose-built precision bolt-action hunting rifle that combines a 416R stainless steel action with a lightweight carbon composite stock.
At $1,849 MSRP, it's positioned for shooters who demand mechanical certainty at the cost of magazine capacity and some raw velocity.
What is the Seekins HAVAK PH3 used for?
The Seekins HAVAK PH3 is for extended-range hunting in open country and ethical precision shots past 400 yards.
Its 20 MOA integrated Picatinny rail and 6-pound unloaded weight make it a natural suppressor host, which is why Seekins chose the common 5/8×24 muzzle thread; adding a quality suppressor like a Dead Air Nomad brings the overall package to around 8.8 pounds, still manageable for a .300 Win Mag system.
How does the Seekins HAVAK PH3 compare to the Stevens 334 Rifle?
The HAVAK PH3 is fundamentally more capable but costs roughly 2.8x more than a Stevens 334 in .308 Win, which retails around $650.
The Stevens is a good, simple budget rifle for sub-300-yard deer, but the PH3's 3-lug 60-degree bolt throw cycles 40% faster, its barrel is stress-relieved and hand-bedded, and its TriggerTech trigger breaks consistently at 2.5 pounds compared to the Stevens' 3-6 pound factory setting—critical differences when a trophy elk is at 550 yards in a crosswind.
What does it weigh and what are the dimensions?
The rifle weighs 6.0 pounds unloaded, measures 42.5 inches in overall length, and has a barrel profile that's 0.825 inches at the muzzle for threading stability.
The 22-inch fluted barrel saves approximately 8 ounces versus a standard profile, a worthwhile trade for hunters covering multi-mile ridges, though it will heat up faster during sustained fire; expect a 1.5 MOA shift after 10 rounds fired in 90 seconds during zeroing.
Who is this NOT for?
This rifle is not for budget-conscious plinkers, new shooters, or anyone restricted to ranges under 200 yards.
The .300 Winchester Magnum recoil (approximately 27 foot-pounds of energy in this 6-pound platform) is punishing without proper technique, and factory ammunition averages $3.50-$5.00 per round.
Its 3-round flush-fit AICS magazine is a hard limitation for target competition; you'd be better served by a chassis rifle like a Bergara B-14 HMR with a 5+1 capacity for PRS-style events.
What's in the box?
The rifle ships with one 3-round AICS-pattern polymer magazine, a thread protector, and basic owner's manual.
Unlike some competitors, Seekins does not include a sling, bipod, or optics mounting hardware; budget an additional $450-$800 for a quality scope, rings, and base.
Is the Seekins HAVAK PH3 worth it at $1849?
Yes, if your hunting or shooting discipline demands sub-MOA consistency from a field-ready, lightweight magnum rifle.
The $1849 MSRP buys you a fully-bedded action, an adjustable TriggerTech diamond-series trigger, and a proprietary carbon stock that's 28% stiffer in torsion than a traditional fiberglass stock—features that would cost $400+ to add to a factory Remington 700.
For hunters who prioritize sheer volume or versatility, a Stevens 555 Sporting O/U shotgun offers two shots for half the price, but for one precise shot at extreme distance, the PH3's engineering justifies the cost.

Pros & cons
What works
- Unloaded weight of 6.0 pounds — critical for mountain hunting where every ounce counts on a 12-mile day.
- TriggerTech adjustable trigger with a crisp 2.5-pound break — 40% lighter and more consistent than most factory rifle triggers.
- Integrated 20 MOA Picatinny rail — eliminates base screws that can loosen under heavy .300 Win Mag recoil.
- 3-lug bolt with 60-degree throw — cycles 33% faster than a standard 90-degree bolt lift for rapid follow-up shots.
Trade-offs
- Limited 3-round magazine capacity — the AICS pattern magazine is flush-fit for handling but restricts practical fire for extended range sessions or competition.
- 22-inch barrel sacrifices approximately 75-100 fps of muzzle velocity versus a 26-inch barrel — a trade-off for maneuverability that affects long-range ballistics.
- Carbon composite stock lacks traditional sling swivel studs on the fore-end — requires an M-LOK adapter ($25-$40) for a standard bipod or sling attachment.

Frequently asked questions
- Is the muzzle threaded for a suppressor?
- Yes, the 22-inch barrel uses a standard 5/8×24 thread pattern, compatible with most .30 caliber rifle suppressors, including the SilencerCo Omega 300 and Dead Air Sandman-S. The thread protector is included, but you must purchase a muzzle device separately.
- What scope base does it use?
- It comes with an integrated 20 MOA Picatinny rail machined directly into the receiver, eliminating the need for a separate base and ensuring repeatable zero. Use standard 1913 Picatinny rings from brands like Seekins Precision, Warne, or Vortex.
- Can I swap the barrel to another caliber?
- Yes, the HAVAK PH3 uses Seekins' quick-change barrel system. A replacement pre-fit barrel from Seekins typically costs $450-$600 and requires a barrel vise and action wrench. Caliber swaps must stay within the same bolt face; .300 Win Mag uses a magnum bolt face (.532"), so you could switch to 7mm Rem Mag or .300 PRC.
- How long is the shipping to an FFL?
- Ironclad Armory processes in-stock firearm transfers within 1-2 business days. Shipping via FedEx or UPS 2-Day Air to your licensed FFL dealer typically adds 3-5 business days. Always contact your chosen FFL for their receiving procedures before ordering.
