is IV8888 a manufacturer? 02?The same Mutant SBR that CMMG had at the IV8888 shoot both years we went they ran so hard that they were dunking it in 5 gallon buckets of ice water. People were lined up all day to shoot it. It had 20k rounds through it with no failures being properly maintained. It got at least 5k rounds each day through it all day long without ever going down. If I got an AR that takes AK mags it'd 100% be a Mutant.
