I had always resisted upgrading the triggers on AR-15s because in the Marine Corps we used stock triggers to accurately shoot from the 500-yard line. With performance like that, how much better could an expensive trigger perform? Well, I intend to find out.

I had read so many good things about The Larue MBT (Meticulously Built Trigger)-2S, that I could no longer resist buying one. The internet assured me that, for $80, there is no better performance for the price. I opted for the straight bow trigger.

The installation process was simple. I did not have to remove the pistol grip or the safety.

I like to line up the new parts next to the old parts so I can make sure that I understand how everything will work once it is installed. The MBT comes with an extra power hammer spring and a standard power hammer spring; I used the standard power.

I used a little bit of grease where the instructions indicated.

The hammer spring legs rest on top of the trigger pin, which keeps the trigger pin in place. The hammer pin is kept in place by a spring inside the hammer pinhole.

A punch can be used to align the hammer, which is under quite a bit of spring tension, so the hammer pin can be inserted.

The trigger pull feels fantastic. It also looks cool. If this new trigger allows me to shoot better or to have more fun while shooting, I guess that is worth $80.

    Looks easy to install. Thanks for the article. I’ll have to give it a try.
