Didn’t feel any noticeable difference in going from gen 2 to gen 3 in 6.5x47 or 6 dasher.
6.5x47 originally had a surefire socom, which sucked, went to a 6.5mm PVA jet blast which was a yuge step up, then tried a LB g2 which was just as good, and now a g3 is on there.
Dasher now wears the PVA jet blast.
IMO the jet blast, gen2 and gen3 are interchangeable with no discernible difference.
But don’t forget, you get extra points in matches if you have the latest and greatest gear.
