Hey all- new to posting, though I've been lurking for a few months. I'm ordering my first evil black rifle in the next few days (del-ton kit on stag lower), and looking to use it primarily for local 2/3 gun events and for range play- HD is a bonus, but not really the point of the gun. I've searched for most of this stuff, but having a hard time finding answers, though I wouldnt be surprised if its all been gone over before. Anyway, my main questions are:
1) optic- it's been debated a million times, but I can't decide between the Aimpoint Comp C3, leupold VXII 1-4x, and vortex viper 1-4x. Heard great stuff about all of them- would the leupold/vortex be almost as fast when at 1x? I don't believe there are a ton of 200+yd 3 gun events around here, and none of these are terribly expensive, just curious if any of those are definite go/ no gos- haven't heard a ton about the C3, other than a few folks who say its the same as an ML3 with a 15ft submersion max.
2) related to optic- would it be worth it to have a front A2 sight for cowitness, a flip up on the gas block, or nothing at all? I imagine the answer is contingent on whether I'm going with the aimpoint or one of the 1-4x scopes?
3) gas system- I apologize in advance, as I'm new to the AR platform, but is there any reason to go with a mid-length gas system over a rifle-length on a 16" barrel? I've seen a number of folks recommend sticking with the rifle on an 18/20" barrel, would this hold true for a 16?
Thanks in advance, if this has all been covered before, I apologize, but I'm having a hard time finding answers for anything other than the first question, which has been debated to the point it makes my head spin.
