Larue Tactical LT1555612MLOK | 5.56 NATO | 12-inch

The Larue Tactical LT15 described here is an AR-platform semi-automatic carbine configured around a 12-inch stealth barrel in 5.56 (.223 Rem/5.56 NATO). It pairs a compact barrel and M-LOK handguard geometry with Larue’s MBT trigger and R.A.T. stock for a balance of controllability and modular accessory mounting. For a dedicated optic under $1,000 that suits this configuration, the Vortex Strike Eagle 1-6×24 provides a clear low-power variable option for close-to-medium engagements and is commonly chosen for compact carbines.

Applications: range training and competitive carbine events (e.g., limited-velocity matches) are well suited to this platform and barrel length, as is precision work at shorter ranges where maneuverability matters.
