>same short eye reliefIt doesn't. The Elcan's eye relief is noticeably longer. It's actually much less forgiving in terms of the allowable front-to-back range, but it's significantly longer.
This can be very helpful for preventing scope eye under certain circumstances.
>worse glass qualitySometimes the ACOG looks sharper sometimes the Elcan looks sharper. Overall at any given point and time there's likely to be little difference in clarity and resolution.
>weighs half a pound moreThat is the cost of the dual role mode and the longer eye relief, yes.
>piss filterActually makes vegetation look more vivid. Your shitbrown environments will lose contrast, but environments with more varied colors will pop more.
>missed out on the ARMS Mk2 leversSad!!!
>uh but it has a 1x that you'll never use, because you mounted a red dot on it instead!Don't mount a red dot on it.
Aside from all of that. the Elcan's eyebox is more consistent across various lighting conditions than the ACOG's. It's a bit smaller on 4x under normal circumstances, but never shrinks much while the ACOG's situationally can. Also you get 2 different modes of illumination and arguably better means of rangefinding.
None of that is to say the Elcan is objectively better. Competitive and viable, yes.
