Key Features

• Element Barreled Action — The heart of the HAVAK line, this action is machined from 416R stainless steel with a 60-degree bolt throw, providing a smooth, short-lift cycle that keeps you on target during follow-up shots. Why it matters: Faster bolt manipulation means less time breaking cheek weld, critical for hunting or competition.
• 16″ Spiral-Fluted, Threaded Barrel — The 1:10 twist barrel is spiral-fluted to reduce weight and increase surface area for heat dissipation, then threaded 5/8×24 for suppressor or brake attachment. Why it matters: You get a compact, suppressor-ready barrel that sheds heat faster than a standard contour, maintaining consistency through a string of fire.
• Trigger Tech Diamond Trigger — A fully adjustable, single-stage trigger with a crisp break and zero creep, set at a factory pull weight of 2.5 lbs. Why it matters: A clean break eliminates shooter-induced error, letting you exploit the rifle’s inherent accuracy potential.
• SLAM Hunting Chassis with Carbon Fiber Wrap — The skeletonized aluminum chassis is wrapped in hand-laid carbon fiber, then topped with a folding stock that locks rigidly when deployed. Why it matters: The carbon fiber reduces weight without sacrificing stiffness, and the foldable design cuts overall length to 27″ for pack carry.
• Integral 20 MOA Picatinny Rail — Machined directly into the action, the rail provides a canted base for long-range optics without needing aftermarket mounts. Why it matters: A built-in 20 MOA rail gives you the elevation travel needed to dial out to 1,000 yards with most scopes, right out of the box.

Who It’s For

This rifle is built for the hunter who also runs precision rifle matches, or the precision shooter who wants a lightweight rig for backcountry use. If you’re the kind of shooter who measures groups in MOA and packs your rifle into the high country, the HAVAK SLAM M3 is your tool. It’s not a safe queen—it’s meant to be carried, shot, and carried again.

Pros & Cons

• Pro: Sub-7-pound weight with a full-length chassis and 16″ barrel makes it one of the lightest production precision rifles in its class.
• Pro: The Trigger Tech Diamond is arguably the best factory trigger available, with a repeatable pull that rivals custom jobs.
• Con: The 16″ barrel limits muzzle velocity compared to a 20″ or 22″ tube—expect about 100-150 fps less with 168-grain loads, which slightly reduces maximum effective range.

FAQ

What is the barrel twist rate on the Seekins HAVAK SLAM M3 .308?

The barrel uses a 1:10 twist rate, optimized for 150-175 grain projectiles common in .308 Win and 7.62 NATO.

Does this rifle come with a muzzle brake or suppressor mount?

The barrel is threaded 5/8×24 and includes a thread protector. No muzzle brake is included, but the threading is compatible with most .30-caliber brakes and suppressors.

Can the stock be folded with the optic attached?

Yes, the folding mechanism is designed to clear most scopes and red dots when folded. The stock locks rigidly when deployed with zero play.

What is the magazine compatibility for this model?

It accepts AICS-pattern magazines. Seekins includes one 5-round magazine with the rifle.

Is this rifle suitable for long-range target shooting beyond 800 yards?

Yes, but with the 16″ barrel, you’ll see a velocity drop of about 100-150 fps compared to a 20″ barrel. With 175-grain match ammo, it’s capable of consistent hits to 1,000 yards, though wind calls become more critical.
