As the title say I can't decide what optic to put on my AR. I have two style in mind ether some model of eotech with a 3x on a flip to side or a 1-4/6x30mm with a P.E.R.P style mount. The gun is mainly on the range but it will be used for things like coyotes and maybe deer and antelope. I would also like to shoot 3 gun if i find any comps in my area. What are some pros and cons of both styles that you guys have experienced?
