FRT or Super Safety in LMT MWS AR10

[NHPiper]

Has anyone run an FRT, Arc Fire, Super Safety or similar in a large frame LMT?

There is a difference in the height of the BCGs between an AR10 and an AR15; the AR10 carrier body is larger in diameter but the tail is turned down to fit in an AR15 receiver extension. The carrier tail needs to contact the FRT the same way an M16 auto sear contacts the carrier tail. The only way for an FRT to work in an AR10 is if the FRT is taller. There is an AR10 FRT on the market, the user has to modify it for the specific platform because of all of the AR10 BCG variations on the market. The ones you mentioned don't work.

Some guys have gotten the 308 super safety to run in LMTs, so I was curious if anyone here had messed with it.

Hope you get one running, sounds like a hoot! Love my Atrius.

I would suspect that a SuperSafety MIGHT work with SOME AR10s. It appears common, that the SuperSafty "dinglehopper" is excessively tall and actually binds on a lot of carriers on it's rearward travel. Plenty of info online of folks needing to slightly file down the height to get smooth reliable functionality.

My SS just got tweaked yesterday and passed a function check, but I haven't even fired it yet.
