does anyone or has anyone ever shot a cmmg m18 spr upper ? wondering how accuracy is with them, i have recently become interesting in the upper, want something rather accurate say 1 moa or less at 100 yrd's my other choice would be looking into fulton's liberater carbine or there varminter seeing "according" to fulton they can shoot 3/4 and 1/2 moa but that could just be a gimmick for all i know.
haven't used the cmmg SPR upper.....but I will tell you I really like the whole SPR idea. Pretty much any of the builders here on the board can build you a 1 moa SPR.
ADCO did mine.....you should check them out
JTAC and MSTN also do very fine work
