Description
LaRue Tactical built its name on quick-detach optic mounts and hyper-accurate rifle systems, and the LT15 is where all of that experience lands in a complete 5.56 NATO carbine. This 16-inch version pairs a CNC-machined LaRue billet upper with a precision-machined billet lower, both wearing a hard-anodized finish that holds up to range days and rough handling alike. It runs a direct impingement gas system and ships with one LaRue-branded 30-round Amend2 magazine, so you're set to load up the moment it clears your FFL.
What Sets the LaRue LT15 Apart at the Range
The heart of this rifle is the stealth medium-weight contour barrel with 1:8 twist rifling, M4 feed ramps, and a 1/2-28 threaded muzzle capped with a birdcage flash hider. That 1:8 twist is the sweet spot for 5.56, stabilizing everything from lighter 55-grain plinking loads up through heavier 69 and 77-grain match bullets. LaRue is candid that the rifle is built to be capable of sub-MOA accuracy, with plenty of owners reporting groups under half an inch when they feed it quality match-grade ammo. Barrel life is rated around 10,000 rounds, so there's a lot of trigger time built in.
Trigger and Furniture That Make the LT15 Feel Custom
Where a lot of factory ARs cut corners, this one comes with the LaRue MBT-2S, widely considered one of the best drop-in triggers in the AR world. It gives you a clean, predictable break that makes a real difference once you're trying to wring accuracy out of the gun. The LaRue R.A.T. stock and matching grip round out the package, and the 14.5-inch free-floating M-LOK handguard leaves you all the room you need to bolt on a bipod, light, or laser.
At roughly 7.4 pounds with a 32.5-inch overall length, the LT15 carries well whether you're working a square range, running drills, or heading into the field. It's a right-hand build aimed at folks who want a hand-built, made-in-USA AR that shoots better than they do and leaves plenty of room to grow.

Frequently Asked Questions
How accurate is the LaRue LT15?
LaRue guarantees the rifle is capable of sub-MOA accuracy, and many owners report groups smaller than half an inch when shooting quality match-grade ammunition. The rifle itself is built to deliver that performance, though the final result still depends on your ammo choice, optic, and shooting fundamentals. Feed it good ammo and it will hold its end of the bargain.
What ammo works best in the 1:8 twist barrel?
The 1:8 twist is a versatile middle ground that handles the full range of common 5.56 and .223 loads. It stabilizes light 55-grain plinking rounds just fine, but really shines with heavier 69 to 77-grain match bullets where the tighter twist earns its keep. If you're chasing those tight groups, lean toward quality match ammo.
Is the MBT-2S trigger really that good?
The LaRue MBT-2S has a strong reputation as one of the best drop-in AR triggers you can get, and it comes installed from the factory here. It delivers a crisp, predictable break that makes precision shooting noticeably easier. It's the kind of upgrade a lot of people pay extra to add to other rifles, so having it standard is a real plus.
Can I remove the handguard or add accessories?
Yes. The 14.5-inch free-floating M-LOK handguard gives you plenty of real estate to mount a bipod, light, laser, or sling hardware right where you want them. The free-float design also helps keep your accessories from putting pressure on the barrel and affecting accuracy.
Does this version come with a 30-round magazine?
This model ships with one LaRue-branded 30-round Amend2 magazine and is rated at 30+1 capacity. Note that LaRue also offers a 10-round configuration of the LT15 under a different part number, so this is the full-capacity build. It's ready to load and run as soon as you take delivery.
