LaRue Tactical MBT-2S 4.5lb Two-Stage Straight Trigger AR-10/AR-15

The LaRue Tactical MBT-2S is a precision two-stage straight trigger engineered for AR-10 and AR-15 platforms. Designed and CNC-machined from solid S7 tool steel, the MBT-2S delivers the durability, consistency, and long service life that have made LaRue triggers a top choice for duty, defensive, and precision rifle builds.

The MBT-2S breaks crisply at a total pull weight of 4.5 lbs, with a 2.5 lb first stage and a 2 lb second stage, followed by a smooth and positive reset. It is built for small-pin AR-15 lower receivers using .154-inch pins, making it a clean drop-in upgrade for most modern mil-spec and aftermarket AR-10 and AR-15 lowers. The black finish provides a clean, professional appearance inside the receiver.

Whether you are assembling a competition rifle, refining a duty carbine, or upgrading a defensive AR-10, the LaRue MBT-2S trigger delivers the combination of a clean break, short reset, and proven reliability that shooters expect from LaRue Tactical.
