Poor 1x and 10x performance - SIG SAUER TANGO-MSR 1-10x26mm Rifle Scope, 34mm Tube, First Focal Plane (FFP)

Had high hopes for this optic since I have the SIG MSR 1-6x and its a great optic. This one not so much. At 1x the center dot is virtually invisible, and the ring around it is so tiny and thin that you can't see it unless its contrasted over a white or very light color object. The illumination is no where daylight bright and won't help find the center in daytime conditions. Optically at 1x it seemed ok, some fish-eye and distortion, but very minimal. If they had a larger ring like an Credo or Vudu, and/or a red dot bright reticle it would be a lot better. The SFP version may be better in this regard as the reticle would not be incredibly small at 1x.

Magnification up to about 6-7x was good, crisp and bright. Going over that the image starts to get milky and things start getting out of focus. You will have to adjust the diopter when going up from 4-6x to maintain the clearest image you can. Up to 8x its still reasonably useable, but once you max out at 10x it really craps out. The overall image falls apart, things are out of focus and its difficult to get what you can in focus with the diopter. Eye box is tight, but still useable in a supported position. Yes, you can still use it to make hits, but the experience is not pleasant and you end up fighting more with the scope than your target.

I compared this to a Swampfox arrowhead 1-10x as its also a value 1-10x, and it is a SFP scope so the reticle is better at 1x, and optically its slightly better than the SIG, especially at 10. The swampfox does suffer going above 6x, but not to the same degree as the SIG optic. The SFP version of this optic might be on par with the Swampfox as SFP optics seem to do better with optical clarity and 1x performance.

The finish (I got a FDE version) was nice and fairly even, included mount was also nice as well as the caps. The side level line was not correct though, so its worth wile to make sure you scope is level, and not to solely trust the line. Click adjustments were not super crisp, but worked reasonably well. Mag throw ring was smooth, and included cat tail is a bonus.

I ended up returning the optic, as the most important aspects, 1x and 10 performance was very poor. 3-8x it was fine, but you would be better off getting the 1-6x LPVO for less cost, or getting a MPVO, like a 2-10 or similar. My $200 Primary arms 4-14 scope was worlds better at the 8x and higher magnifications than this. The Sig MSR 1-6x is a really nice scope, so I would go that route. Their 1-8 or 1-10 SFP might be good, but I suspect the optical quality of both will suffer a little above 6x.
