    LaRue MBT2S weak reset

    I have a MBT2S. The break is great but the reset seems weak or slow.
    Does anyone else feel this way about the MBT2S?

    Any alternative 2-stagers that are made from billet steel and not cast?

    Have you reached out to Larue about the issue? I do not have any reset issues with my Larue's triggers.

    I am not aware of a trigger that is machined form billet. Geissele which are hands down some of the best triggers in the world come from investments casts. May be worth your time - https://www.m4carbine.net/showthread...5982#post65982

    What trigger spring did you use?

    I used the non-heavy spring. Would switching over to the heavy one make the reset feel more solid? Isnt that one just for a heavier 2nd stage?

    No, it replaces the trigger not hammer spring. It's directly responsible for reset.

    Ahh, Ok thanks. I will probably hold off on swapping to the other spring. I don't want an 8 pound trigger. Maybe I just have to wear it in more. The fit is insanely tight because of how wide that trigger is. I think it slightly rubs against the lower where the trigger pokes through.

    That’s just a characteristic of that trigger.

    If it’s rubbing the lower I’d trim the trigger, not the lower. But you’re gonna need a good file because S7 is tough!

    No,

    What lower is it in?
    How does it shoot with it?
    Are you using LaRue trigger pins or something else?
    Have you used any other trigger in the lower and what were the results?
    Have you reached out to LaRue?

    If you feel your trigger is unserviceable or rubs the slot in the lower, contact Larue for assistance.

    The MB2S has a less forceful reset than a MilSpec or G 2-Stage trigger. Pretty much every review ever posted about the trigger states that. The heavier trigger spring increases trigger pull by roughly one pound (not to 8 lbs) and firms up the reset.

    The perfect AR trigger doesn't exist...

    Perhaps the rubbing is contributing to the weak reset?

    My MBT2S is fantastic with the weaker spring in a BCM lower.

    I went from 4.9 to 5.5 pound trigger pull weights (all over the place) with the mil spec trigger to 4.1 pounds consistently across the graph with the MBT2S.
