When it comes to your system keep is simple, that means eliminate all possible chances for SCREWING THINGS UP. No converting between knob values and reticle values, no crosshairs that change value at different magnifications, no turrets with less than 40 MOA of adjustment per rotation of the dial, no running out of elevation adjustment before you reach the subsonic distance of the cartridge you are firing.
1) Repeatable adjustments
2) Click values = what they claim them to be (I don't want to talk about my .44 MOA clicks that were supposed to be .5 moa and fighting with the scope company for months about the issue)
3) At least 90+ MOA or 26+ MILS of travel, if you ever want to get to that mile mark you gonna need it and with our large caliber conversion kits you can easily do it.
3) High travel per rotation of the knob, PLEASE don't buy a scope with more than two full rotations of elevation adjustment. (I am having nightmares of turning my old nightforce scopes 6.5 full rotations to get to 1 mile and loosing my place on the dial when jumping back and forth between distances.)
4) Second Rotation Indicator, this tells you when you are on your second rotation to prevent you from getting off a rotation and blowing a shot, my favorite is the S&B yellow flag system on there PMII scopes.
5) Front focal plain reticle (this means your great measuring lines are accurate at any magnification, YOU WANT THIS TRUST ME!!)
6) Mil or MOA scaled reticle with MATCHING KNOBS!! (some US services are still running mildot reticles and MOA turrets in their scopes so snipers have to constantly convert between MILS and MOA which is an opportunity to screwup and slows things down. Running reticle and knobs with same values no slow conversion process is required.
7) Magnification is less important than all the other items above assuming you are running a variable power scope with a top end of 12x or more. Once you get over 20x mirage becomes a big problem and doesn't help.
8) Strong tube/housing that can take a beating
9) Light Weight if there are two scope options that are comparable and one is 3 lbs and the other is 1.5 lbs, get the lighter scope.
10) Short as possible allowing for night and thermal optics to be mounted forward of the dayscope
Will clean this up in the morning, too freaking tired gotta get some sleep.
