What were the design flaws you are talking about?
This was on my MK12Mod1.
- It's heavy as hell. Switching back to a NF 2.5-10 and NF mount saved almost a pound of weight from the USO setup
- You practically need the extended scout ADM mount or something similar to really crane the scope forward as the eye relief / eyebox is fairly unforgiving especially at 1x and witha regular mount you'll have your stock fully extended out to use the USO.
- The extended mount puts it so far forward the rifle had the weirdest (in a bad way) balance I've ever had; was very counterproductive to using the red dot and CQB shooting.
- 2 of the ones I looked through had some sort of epoxy like seal around the objective lens; it can be seen looking through the glass.
- The way the turret housing is set up it leaves you absolutely zero room to move your optic around while in the rings/mount and any scope forward/rear adjustments on setup are done via rail space only.
- Target acquisition with the red dot is not fast due to the very unforgiving eyebox at 1x and you tend to either shoot with part of your sight picture blacking out or wait to 'center' your shot which adds time to your acquisition process
- The red dot is nothing like an AimPoint/Eotech reticle and suffers from parallax; this kind of defeats most of the purpose of it for me and offers little benefit over a different optic with a Doctor or RDS mount.
- The reticle I had (C2) had very thick lines/sub-tensions and was subtended in 1 mil increments. Combining only 8x on the high end, a small field of view, a very thick/bulky reticle and 1 mil increments this made ranging and holdoffs much much more difficult than they needed to be.
- The turrets increment in .2 mils so that is either a bonus (faster) or a negative (less precise adjustments) depending on what you're wanting.
- There is no zero stop and if you have the turret with about 2 or 3 revolutions from bottoming out, there is no visible vertical line to indicate what setting your turret is currently on.
- The red dot, from the way its built/designed (not sure how they did this) isn't actually centered and is made up of what looks like multiple dots (kind of like an Eotech). Problem is, from the 3 I've looked through, the pattern is different in each optic and some are slightly off center.
- CQBSS glass > this glass
It tries to do everything but excels at nothing.
