I've been messing with 5.56 MKE rifles for some years, and have found them very appealing for NFA builds. It seems their barrels, are second to none for accuracy. My 33K, holds 2-3" groups at 50 yards, bagged and on 3rnd burst. All my buddies were amazed at an outdoor range, as they could knock stuff all over the berms without any difficulty on burst.
I have an Elcan DR optic on it now.
