Das iz no BS! My Vortex Razor 1-6 Gen 2, Non-E comes in at 25.5 oz. paired with a BOBRO 30mm Extended QD mount tops out at 33 oz. Weight isn't a factor for me since I'm usually proned out or on a bench with the Noveske.
On a lighter note, Aimpoint Micro H-1 3.5oz. + BOBRO Micro QD 1/3 Co-witness mount 3.9oz.
