I have one. It's a dream to shoot. Very light, accurate and very handy for a truck or brush gun. I already have a few blackouts and probably gonna sell this one and move on to 300hamr AR instead.
I shoot 125sst with H110 and it clovers at 100 yards. Bergara fluted barrel.
One weird thing is that it's 1/2x28 tpi not 5/8x24
