Key Features

• Ambidextrous Controls: WHY IT MATTERS — left-handed shooters and weak-side transitions become seamless, shaving seconds off your stage times or follow-up shots.
• 16-inch Barrel with 1:8 Twist: WHY IT MATTERS — stabilizes both 55-grain plinking loads and 77-grain match ammo, giving you sub-MOA potential from a compact package.
• M-LOK Handguard with Full Picatinny Top Rail: WHY IT MATTERS — mount your bipod, LAM, or clip-on thermal without adapter plates, keeping zero shift to a minimum.
• CK Green Cerakote and Anodized Finish: WHY IT MATTERS — low-visibility color reduces glare in the field, and the hardcoat resists corrosion better than standard black anodizing.
• Lightweight Aluminum Receiver Set: WHY IT MATTERS — shaves nearly half a pound off a standard mil-spec lower, making this rifle viable for long days on the range or in the backcountry.

Who It’s For

This rifle is for the precision shooter who wants a lightweight, ambidextrous platform for PRS gas-gun divisions, tactical matches, or varmint hunting. It’s also a strong choice for the left-handed shooter who’s tired of aftermarket bolt releases. If you’re building a competition gun and don’t want to spend time swapping parts, the Pro Light comes ready out of the box.

Pros / Cons

• Pro: Sub-6-pound weight makes it one of the lightest 16-inch ARs on the market at this price point.
• Pro: Factory ambidextrous controls are rare in this price bracket — you’d spend $200+ on a conversion set.
• Con: The lightweight barrel profile heats up faster during sustained fire — expect stringing after 60-80 rounds in a match scenario. Plan your shot cadence accordingly.

FAQ

What is the twist rate on the 16-inch barrel?

1:8 twist, per Cobalt Kinetics specs. This handles everything from 55-grain bulk ammo to 77-grain OTM match loads without keyholing.

Does this rifle accept standard AR-15 magazines?

Yes. It uses any mil-spec AR-15 pattern magazine (30-round included). The lower is cut for standard mags, not proprietary.

Is the handguard free-floated?

Yes. The M-LOK handguard is free-floated and attaches to the barrel nut, not the gas block. This prevents barrel harmonics from shifting under pressure.

What is the weight of the rifle as configured?

5.8 pounds empty, per manufacturer specs. With a loaded 30-round magazine and optic, expect roughly 7.5-8 pounds.

Can I use this for 3-Gun or PRS Gas Gun division?

Yes. The 16-inch barrel and lightweight build make it ideal for 3-Gun. For PRS, the ambi controls and M-LOK rail give you the modularity to add a bipod and bag rider.
