    LMT Mars-L Ambi

    Anyone know if the bolt catchers are independent from each other? also, does it need a special bolt carrier to have ambi bolt catch features function properly?

    The bolt catches are independent. The traditional side bolt catch has a cut out that accepts the ambi side bolt "flapper".

    I'm pretty certain you don't need any special bolt carrier.

    Derp. Yeah, they are connected. If you move one, it will actuate the other side.

    For some reason I thought you were asking if it was a one piece system like a PDQ.

    They do not require different bcgs. My favorite lower in the market right now.

    The trigger guard area where you press the roll-pin is a little more "meaty" than milspec, some aftermarket trigger guards do not work (KAC and MAGPUL enhanced metal versions that came with the screws instead of the rollpin--the enhanced MAGPUL with roll pin works--no idea what was changed. MAGPUL polymer guards work). The pivot pin can be REALLY tight. I'm still working on fitting one upper/lower together that is actually too tight. They are great lowers, no regrets. If you are buying an MRP to go on top of it, make sure you torque your barrel to spec using the LMT torque wrench tool--if it's not on the gnat's ass you will have issues. I'd like to see what LMT recommends in terms of maximum number of barrel changes you can make on a single set of screws. Personally, I'd want a new set every time if I was going to swap it, they have to stretch a little with as much torque as you need to apply.

    MARS-L lower's bolt catch has a key where the right hand bolt catch/release lever rides in. It is a neat setup. Any BCG will work.

    I dig my MARS-L rifle...to me...it is the best AR15 design. Hands down.

    My two go to rifles are LMT MWS 13.5" and the LMT MARS-L
