Ncstar vism scope

[Inka]

I'm looking at the NcStar Vism Eco 4x34 scope and the Gen3 Mark III 3-9x40. Any one uses or has use one of these scopes?, are they any good, build quality, lenses clarity, do they have a good aiming reticle? How about eye relief?  Etc. I would like to get a red dot and scope with some magnification combo. New to airsoft

Thank you

I'd say go for a 1-4X short dot over a stacked optic. I've tried it and ended up almost exclusively using the red do as I've found 4x too much for most airsoft engagements
