I shot one briefly indoors and it was impressive for how light weight it was. Sounded good and it was low back pressure. Which was good cause I don't find their guns special at all.
That being said, I think a super lightweight 5.56 is not a very smart idea. I'd regulate something like this to a bolt gun (but you don't need LBP on manual action stuff), so I'm not really sure where this fits? DMR style rifles with light firing schedules?
If for some odd reason you'll be in utah on 6/1, CGS and cobalt will be demoing at my event. I was told the scrambler will be there.
