Paired with the EXPS3 in the 2 or 4 dot reticle this is a nice addition to the lineup. The dimensions really are basically identical to the G33. Perks are the additional magnification with no significant change to weight or size. The eye relief/box is slightly more picky than the G33 but worth it. I love that I can have 5x magnification that I can take off quickly with the QD mount and toss in my bag when I don’t want the weight, unlike a LPVO.
