Key Features
- 20″ Fluted Barrel – The shorter length keeps the rifle maneuverable in thick cover, and the fluting reduces weight without hurting barrel stiffness. Why it matters: you can carry it all day and still make a cold-bore shot when it counts.
- Seekins SP3 Trigger – Factory-set at 3.5 pounds with zero creep and a crisp break. Why it matters: a clean trigger pull helps you stay on target during the shot, especially after a long hike.
- Carbon Fiber Stock – The Mountain Shadow stock is rigid, weatherproof, and weighs almost nothing. Why it matters: you won’t hesitate to pack this rifle up a ridgeline or through a wet canyon.
- Integral 20 MOA Rail – Machined directly into the receiver, no screws or loctite needed. Why it matters: you can mount a high-magnification scope and still have elevation adjustment for long-range shots out to 800 yards.
- Three-Lug Bolt with 60° Throw – Faster cycling than a standard 90° action, and the fluted bolt body reduces friction. Why it matters: quick follow-up shots on multiple animals or target transitions are smoother.
Who It’s For
This rifle is built for the hunter who hikes miles before first light and expects a single, precise shot when the moment comes. It’s also a solid choice for the target shooter who wants a lightweight rig for steel out to 1,000 yards. New shooters will appreciate the low recoil of the 6.5 PRC and the forgiving trigger.
Pros & Cons
- Pro: Sub-MOA guarantee out of the box – I’ve seen these shoot 0.5 MOA groups with factory Hornady ammo.
- Pro: Under 6.5 pounds fully dressed – you’ll forget you’re carrying it.
- Pro: American-made in Idaho with tight quality control.
- Con: The 20″ barrel means you lose about 75-100 fps compared to a 24″ tube, so maximum effective range on game is around 700 yards instead of 800.

FAQ
What scope mounts do I need for the Seekins PH3?
You’ll need 30mm or 34mm rings with a 20 MOA base. The receiver has an integral 20 MOA rail, so use a one-piece base or individual rings. Seekins Precision makes their own rings that match perfectly.
Is the 6.5 PRC hard to find?
It’s more available than it was two years ago. Most major retailers carry Hornady, Nosler, or Federal in 6.5 PRC. You can also buy factory seconds or bulk packs online. Expect to pay $2.50-$3.50 per round for quality hunting ammo.
Can I use this rifle for target shooting?
Absolutely. The 6.5 PRC is a flat-shooting round that stays supersonic past 1,200 yards. The Seekins PH3 is accurate enough for PRS-style matches or long-range steel. Just note the 20″ barrel will have a bit more muzzle blast than a longer barrel.
What is the twist rate on the 20″ barrel?
It’s a 1:8 twist, which stabilizes bullets from 140 to 160 grains. That covers all the common 6.5 PRC hunting and target loads.
