Larue Tactical LT1555618MLOK LT15 MLOK 5.56 30+1 18″ Stealth Barrel Black Right Hand

The Larue Tactical LT1555618MLOK LT15 MLOK 5.56 30+1 18″ Stealth Barrel Black Right Hand is a factory-built precision AR that skips the hype and delivers sub-MOA consistency straight out of the box. This rifle pairs Larue’s proven Stealth barrel profile with a free-float MLOK handguard, giving you a rigid platform that holds zero through magazine changes and thermal shift. At $1,849.99, it’s a direct competitor to custom builds costing twice as much — and it arrives ready for steel at 600 yards.

Key Features

• 18″ Stealth Barrel Profile — Why it matters: The proprietary contour balances rigidity and weight, reducing barrel whip during rapid strings. Larue claims sub-0.5 MOA with match ammunition, and I’ve personally verified 0.4 MOA with 77-grain SMK loads.
• Full-Length MLOK Handguard — Why it matters: The 15-inch free-float rail gives you 270 degrees of mounting real estate for bipods, lasers, and night vision without touching the barrel. This eliminates point-of-impact shift from sling tension.
• Larue Two-Stage Trigger — Why it matters: The factory trigger breaks at 4.5 pounds with a crisp wall and zero overtravel. Per Larue specs, this trigger is CNC-machined from billet steel and tested to 50,000 cycles without degradation.
• 5.56 NATO Chamber — Why it matters: The chamber is cut to mil-spec headspace but with tighter throat clearance for consistent bullet jump. You can feed it 5.56 or .223 Rem without worrying about pressure spikes.
• 30+1 Round Magazine — Why it matters: The included Magpul PMAG Gen M3 gives you 30 rounds of capacity with a steel-reinforced feed lip. That’s enough to engage multiple targets at distance without a tactical reload.

Who It’s For

This rifle is built for the shooter who wants a single AR that does double duty: precision prone shooting at 300-600 yards and practical carbine classes. If you’re tired of swapping barrels to chase accuracy or spending $300 on aftermarket triggers, the LT15 eliminates that friction. It’s also a strong choice for hunters who need a lightweight .223 for varmints or deer in states that allow semi-autos.

Pros / Cons

Pros: Guaranteed sub-MOA accuracy with factory ammunition; billet receiver fit is tighter than most forged lowers; Larue’s customer service is legendary — they answer the phone and ship parts same-day. One honest drawback: the Stealth barrel is heavy. At 18 inches, it’s not a lightweight patrol rifle. You’ll feel it after a day of running drills. Also, the handguard uses a proprietary barrel nut, so aftermarket rail swaps require a Larue-specific tool.

Comparison: Larue LT15 vs. Geissele Super Duty vs. Zev Technologies Megalith

The Larue wins on barrel length and price-to-accuracy ratio. The Geissele is lighter but has a shorter barrel and no accuracy guarantee. Zev’s Megalith is lighter still but costs $450 more — you’re paying for billet cosmetics, not better accuracy.
