Any Opinions On The G5 Optix Rock Sight? So I'm looking to upgrade my sight and the local shop has a G5 Optix Rock Sight that has caught my eye. I heard they are supposed to be pretty durable, but have not heard much else on them. So before I drop the money down, I was just wondering if anyone has had any experience with one and an opinion on them? Any help would be appreciated. Thanks in advance.
