Picked up a Sig Tango MSR 1-6x last week, $400 down to $250, with what seems to be a fairly sturdy 1 piece mount included. I know, I know, Chinese made, cheap price, pure crap, right? Very impressed with this optic for the money. I come from a background which includes 1st Ranger Battalion Sniper PSG time, various competitive shooting disciplines, instruction, etc. I've used everything from the top Nightforce stuff, Leupold, Vortex, Zeiss, etc. Now, I'm not saying this is as good as a high end optic, but it blows away any lower priced optics that I've had on AR's and back-up guns in the past. 30mm tube, solid build, adjustments/clicks seem positive, it tracked well when zeroing, and glass is pretty decent. I have a few hundred rounds through it, I've bumped it around some, and I've experimented with grouping at 1x, 3x, and 6x power to seem if impact changed at 100m, no issues at all. Reticle is great, and illumination is decent in low light, although its not super bright in daylight. I prefer no illumination in daylight anyway, the black horseshoe in the center of the reticle is easy to pick up for quick shots. With Winchester 69gr Match, 3/4 MOA 5 shot groups at 100m off a bipod. I'll be taking out to play with the BDC reticle on steel from 100-800m this week, should be fun! I will update if I experience any issues with optic in coming months. -Dustin
