Black Rifle Arms has developed the most innovated Gas Piston Systems
This is the long-awaited straight bow (SB) version of the popular curve-bowed MBT-2S. Many precision and competition shooters prefer a flat-faced trigger for greater surface area against the finger-pad and ease of bore indexing from a variety of hasty shooting positions, resulting in faster intuitive shots.Just like the standard MBT-2S, it's CNC-machined out of solid S7 tool steel. Meticulously built by our staff toolmakers ... without a stopwatch in sight. 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-SB breaks crisply at 4.5 lbs (2.5 lb first stage, 2 lb second stage) and has a smooth and positive reset.Everyone also knows that LaRue Tactical has a track-record of doing things right. The LaRue MBT-2S-SB is purposefully designed and manufactured to render the greatest benefits from our legendary line of accurate rifles. The MBT-2S-SB can also replace the stock trigger on any mil-spec AR10/AR15 lower receiver.
