1. The scope is a really harsh light blue color. The actual sight is only very slightly blue colored.
2. The field of view seems small, or the sight seems small. Something about it is a little strange with how it looks aiming down the sights. Considering a lot of sights in-game get a big field of view boost I would guess that.
3. The dot is a little too small
4. M68s are not totally dominant, some EoTechs and iron sights still float around from what I've heard and read.
