In a world of instantly M.I.M.'d rifle and pistol components, LaRue threw on the brakes, slowed to a walk, and built 2-stage triggers out of solid S7 tool steel plates. Meticulous triggers built by their staff toolmakers... without a stopwatch in sight.
No question, they’re particular about accuracy. Everyone knows that one of the smartest improvements an AR-owner can do to their rifle is a precision trigger upgrade. Everyone also knows that LaRue Tactical has a track-record of doing things right. The LaRue MBT-2S was purposefully designed and manufactured to render the greatest benefits from our legendary line of accurate rifles. The MBT-2S can also replace the stock trigger on any mil-spec AR10/AR15 lower receiver.
Sparing no expense, all major components are precision-machined from S7 Tool Steel. The result of this extra effort is a glass-smooth, hyper-consistent trigger that will satisfy even the most scrupulous competition shooter, but also be overly rugged for the battlefield. The MBT-2S breaks crisply at 4.5 lbs (2.5 lb first stage, 2 lb second stage) and has a smooth and positive reset. Each trigger comes with an additional "heavy" trigger spring that increases the pull weight to 6 lbs.
Made in-house by LaRue, in Texas, in the USA.
NOTE: This trigger only works with Small Pin Lower Receivers/.154
