FRT or Super Safety in LMT MWS AR10
- Thread starter NHPiper
- Start date
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.
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.

I run one on a small frame. It works...unless you point the gun down and try to charge it. Then the BCG still hangs up despite lots of sanding. Hopefully will report back here at some point.
hopefully someone has gotten one to run in the MARS-H. I am putting together an AR22 that is a lot of fun to play with. It takes some tuning to get them right (I started with a 4.5" barrel but now have a 16" to try to get it to run more reliably and hopefully with subs and a can). Not that I would want to feed a 308 SS but it would be fun to know that it would work if I wanted to play with one..
FYI here is the link to the cad/stl file for the 308 AR10 specific lever needed for the AR10's. Haven't read of anyone trying it specifically in the LMT.
Gray Market Research also has a specific AR10/308 variation that looks good. It's being used on Aero M5 lowers for sure.

just found this on Reddit (original posting and author were deleted but some info still in the thread):
"Its all factory internals it has a full auto lmt bolt but I also ran it with a aero prescision ar10 bolt except for the super safety lmt h3 buffer 13.5in 308 barrel and grey market research 308/ar10 super safety kit there are new levers that are 3d printed that are on the way that I will also try when they arrive some people needed minor fitting mine with the lmt bolt was dropped in"
sounds like he used the GMR AR10 variation and only had to do some light sanding on the lever to get it to work in the MARS-H

After buying...i kinda wish I would have picked up an ARIZONA REGULATOR first. Seems like the best of all the options and it's not linked to one system. It's swappable.
Do those fit the AR10 platform? Nice that you can run a 3 position and also swap these between uppers.
Those do not work in a AR-10. The trip is too short to contact the rear of the carrier.
