Wife's 16" 6 ARC wears a 3-9x40 Huron and the reticle lines up perfectly at 100, 200, 300 yards at average altitude/temps. Wife has a self imposed 300 yard limit for the time being.She is not going to be a long range shooter, so equipment and gear, including cartridge choice, that works close is good.
Since the 6X SWFA is sold out, how about a second choice on optics.
The trijicon huron 3-9x40 standard reticle is on sale at eurooptic right now. This seems like a decent option with a nice clean uber simple reticle.
Edit: with 108gr M's.
