I keep purty good notes and color coordinate to boot,to make sense outta it all. No thang.
The glass you cite is a MK4 M3 6x and like all fixed MK4's it's a 40mm objective. Got 'em in 10x and 16x,though they'd not be my preference on a Utility Gasser.
And another piece of [bleep] schit 4.5-14x.
smokingpoles,
I get it that you know better than to try to talk rifles with me and I'm enjoyin' your long/awkward silence in regards to your Secret Squirrel Mission!
