The Shark Coast Tactical Arctic White 5.56 16-inch M-LOK 30rd is a custom AR-15 that breaks the mold with a white pearl Cerakote finish carrying a subtle bluish tint across the upper, lower, and handguard. Chambered in .223 Rem/5.56 NATO and fed by a 30-round magazine, this rifle delivers a balanced platform for range work, training, and sport shooting without the tactical-clone look. The 16-inch threaded barrel and M-LOK handguard keep you modular, while the Magpul SL-K stock trims weight. Per manufacturer specs, the Cerakote resists wear and maintains its distinctive finish through repeated use.

Key Features
- White Pearl Cerakote with Bluish Tint — Why it matters: This isn’t a rattle-can job. The multi-layer Cerakote bonds to the aluminum and steel, resisting chips and corrosion while giving you a finish that stands out on any line or in any safe. The bluish tint shifts under different light, so it never looks flat.
- 16-inch Threaded Barrel (1:8 Twist) — Why it matters: The 1:8 twist rate stabilizes 55-77 grain projectiles, covering everything from cheap plinking ammo to match-grade 77-grain OTM loads. The threaded muzzle (1/2×28) accepts your choice of brake, suppressor, or flash hider without gunsmithing.
- M-LOK Handguard (15-inch) — Why it matters: Full-length M-LOK slots let you mount bipods, rails, or sling points exactly where you need them. No keymod, no proprietary nonsense — just standardized attachment points that hold zero under recoil.
- Magpul SL-K Stock — Why it matters: This is the lightest collapsible stock Magpul makes, shaving ounces off the rear end without sacrificing cheek weld or battery storage. The slim profile clears plate carriers and barricades cleanly.
- Right-Hand Lower Assembly — Why it matters: Standard AR-15 controls mean compatibility with every aftermarket trigger, grip, and safety. No left-hand conversions, no proprietary parts — just drop-in upgrades as you see fit.
Who It’s For
This rifle fits shooters who want a distinctive platform for 3-gun, steel challenge, or range practice without the flat-black uniformity. If you already own a safe full of dark rifles and want something that photographs well and starts conversations, this is your build. It also suits left-handed shooters who don’t need an ambi lower — the standard right-hand setup keeps parts commonality high.
Pros / Cons
- Pros: Unique finish that stays put, modular M-LOK for gear attachment, lightweight build at 6.4 lb, standard AR-15 parts compatibility, 1:8 twist handles heavy match bullets.
- Cons: White finish shows carbon residue faster than dark coatings — you’ll want to wipe the bolt carrier and chamber face after each session. The bluish tint may not match every shooter’s aesthetic; it’s a specific look.

The Zev OZ9C is a pistol-caliber carbine, not a direct competitor, but it shows the price delta for a custom finish. The Geissele Super Duty is a battle-ready rifle with a proven track record, but at over double the price. The Shark Coast Arctic White gives you a unique look and solid specs for under a grand — a meaningful value gap.
FAQ
What twist rate is the barrel?
1:8 twist, which stabilizes bullets from 55 grains up to 77 grains. Good for both 55-grain FMJ plinking and 77-grain match loads.
Is the handguard free-float?
Yes, the M-LOK handguard is free-floated, meaning it doesn’t contact the barrel. This improves accuracy by eliminating pressure points that can shift point of impact.
What muzzle device is included?
The rifle ships with a standard A2-style flash hider (1/2×28 threads). You can swap it for a suppressor, brake, or compensator without tools.
Does the Cerakote require special cleaning?
No. Use standard CLP and a nylon brush. Avoid abrasive pads or steel wool. The finish is tough, but white shows carbon — a quick wipe after each range trip keeps it looking fresh.
Is this California compliant?
This model ships with a standard 30-round magazine and standard stock. For California compliance, you would need a fixed magazine or featureless build. Check your local laws before ordering.
