The larue mbt-2s was purposefully designed and manufactured to render the greatest benefits from the legendary line of accurate rifles.The mbt-2s can also replace the stock trigger on any mil-spec ar10/ar15 lower receiver.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 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.Model: MBT-2S
