So I mounted my MAMS to My SR15 Mod1. I needed to use 2 shims to get the post to line up at the 12 o'clock position. my question is is this normal to need 2 shims, and is it normal that I can fit my fingernail in-between the 2 shims? I torqued it to 20 foot pounds and used the included rockset. I shot about 100 rounds through it with no issues. I'm still considering sending the upper to Marvin Pitts to have it cut to 14.5 and have the MAMS pinned and welded...
