Aimpoint pro red dot - Aimpoint PRO 1x38mm Reflex Red Dot Sight

Purchased this Aimpoint PRO to replace an Eotech. The dot is slightly larger (2 MOA) than the Eotech's (1 MOA) but shooting at 100 yards the dot doesn't significantly obscure the PoA. The PRO aligns well with my Eotech 3X (flip to side mount) magnifier...using the installed spacer in the PRO but no spacer in the Eotech 3X magnifier. There may be a millimeter difference in the optical centers of the two rail-mounted devices but that is not noticeable to the naked eye and does not appear to impair function in any way. The mounting system is unique and seems to give a solid grip on the rail. Pretty hard to beat the PRO for the price.
