Seekins Havak SLAM M3 6.5 PRC Woodland Shadow

The Seekins Havak SLAM M3 6.5 PRC Woodland Shadow is a lightweight, modular bolt-action rifle built for serious hunters and precision shooters who want a rig that pulls double duty without the extra weight. It pairs the proven Element barreled action with the SLAM hunting chassis—skeletonized aerospace-grade aluminum wrapped in hand-laid carbon fiber—to deliver a sub-7-pound package that still shoots like a heavy bench gun. The spiral-fluted, threaded barrel and integrated 20 MOA rail mean you’re ready for optics and a suppressor right out of the box.

Key Features

• Spiral-Fluted, Threaded Barrel – Reduces weight and improves heat dissipation, with a 5/8×24 thread pattern ready for a suppressor or brake. Why it matters: You get faster follow-up shots and quieter hunting setups without adding a gunsmith bill.
• Integrated 20 MOA Rail – Machined directly into the receiver for zero shift under recoil. Why it matters: Dial in long-range shots past 800 yards without maxing out your turrets.
• SLAM Carbon Fiber Chassis – Skeletonized aluminum frame wrapped in hand-laid carbon fiber drops weight while maintaining rigidity. Why it matters: Carry this rifle all day in the backcountry and still get bench-rest accuracy when you glass up a buck.
• Long Action with 6.5 PRC Chamber – The long action feeds the hot 6.5 PRC round smoothly, giving you 300+ ft-lbs more energy at 500 yards than a 6.5 Creedmoor. Why it matters: You’re elk-ready with a flat-shooting cartridge that doesn’t beat you up.
• Woodland Shadow Cerakote Finish – A durable, low-reflectivity coating that blends into forest and mountain environments. Why it matters: Stay hidden from game and protected from rust in wet weather.

Who It’s For

This rifle is built for the hunter who wants one gun for both spot-and-stalk and long-range precision work. If you’re a recreational shooter stepping up from a factory Remington 700 or a first-time buyer who wants a do-it-all rig without the weight penalty, the Seekins Havak SLAM M3 6.5 PRC Woodland Shadow fits the bill. It’s also a solid pick for PRS-style hunters who compete in tactical rifle matches and need a lightweight build that still holds sub-MOA at distance.

FAQ

What barrel twist rate does the Seekins Havak SLAM M3 6.5 PRC use?

The barrel has a 1:8 twist rate, which stabilizes 140- to 160-grain bullets perfectly for the 6.5 PRC cartridge. That’s the sweet spot for hunting loads like Hornady ELD-X or Berger VLD Hunting.

Can I mount a night vision or thermal scope on this rifle?

Yes. The integrated 20 MOA rail is Picatinny-spec, so you can mount any NV or thermal optic with standard rings. Just make sure your optic has enough eye relief for the long action.

Is the Seekins Havak SLAM M3 compatible with aftermarket triggers?

It uses a Remington 700-style trigger footprint, so you can drop in a Timney or TriggerTech unit without any gunsmithing. The factory trigger is adjustable from 2.5 to 4 lbs.

Does this rifle come with a muzzle brake?

No, it ships with a thread protector installed. Seekins offers their own brake as an add-on, or you can run a suppressor directly on the 5/8×24 threads.
