I recently picked up a stripped LMT MARS-H lower receiver. I know it ain't KAC but I figured it was the closest thing and plays nice with KAC parts. I don't even know what I'm going to build with it yet but I'm at least starting to look at lower parts. I'm a total novice on the large frame AR's but I know things aren't streamlined like the small frame.
I'm a big fan of the Battle Arms pins and wanted to know if they would work on LMT/KAC lowers. Pin Link
BAD told me pins are .2765" diameter so if anybody can chime in and let me know I'd appreciate it.
