Zero Compromise Optics has set the next standard in magnification, imaging performance & mechanical precision with this scope. With its 8-40x magnification & unsurpassed resolution, this optic transcends anything you've ever seen before. The ZC840 has an elevation adjustment range of 28mils & a field of view of 4.6m/100m - 1.0m/100m at 40x magnification, giving shooters a substantial image to keep their target in view.

FEATURES:
  • 36mm Main Tube
    The tube delivers optical and mechanical systems that work in unison for supreme performance & no compromises. With more internal room, optical components are better protected to withstand external distortion, stress and impact. Further, extra room means ZCO can deliver larger lens components for remarkable optical quality while providing massive amounts of elevation and windage travel. In this case, big is better; significantly better.
  • 56mm Objective with ED Lenses
    ZCO scopes use Extra-low Dispersion (ED) lenses for the objective components to maximise resolution, colour correction and contrast. These larger-lens components bring better light transmission, flatness of field, and premium resolution.
  • Turrets like no other
    Very audible, super-precise, perfect visual alignment and lockable; these turrets provide the ultimate in consistency and repeatability. Elevation and windage click-spline mechanisms are built using hardened steel that's eroded cut for the highest level of precision. They also have a large adjustment range for elevation and windage travel.
  • Real Rugged
    Every material has been carefully selected for its ability to withstand constant cycling with zero compromises to performance. Critical junctions and mechanical areas are stronger thanks to a thicker cross-section in specific areas.

Best non-slip no show sock!
Size: 6-10, Color: Black
I love these socks! I wear them mostly with my slip on vans. The are thin so your feet can breathe (I hate thick socks). They have a grip on the heal so that they don't slip off of your feet, and it actually works! My only negative about these socks would be that if you have bigger than a size 8 foot, I would not purchase them because they do run a bit small. I wear a size 7 and they fit perfectly! They do look very tiny upon unpacking, but they stretch to the according size. I would also recommend letting them air dry after washing them and not putting them in the dryer. The first pair I purchased, I made the mistake of drying them and they shrank to an unbelievably small size. I've had my second set of socks for over 4 months now and have not had any problems since Ive been air drying them. I have not encountered any problems with them tearing as other have stated. Even though these are thin socks, they seem to be made quite well in my opinion.

I buy these again and again through the years!
Size: Medium, Color: Austin Brown Assorted (6-pairs)
Love these. After a year or two I wear holes in the bottoms because I wear them so much. Worth the little bit higher price because of the fit and comfort. Love how they are truly no show

Good quality but tight on toes
Size: 6-10, Color: White/Assorted
These are great socks that stay in place, but they scrunch my toes together like crazy. My feet are normal width. When I first started wearing them I noticed my feet would ache after an hour or two.

My New Favorite Socks
Size: 6-10, Color: Halo Gray/Assorted
These have quickly become mine and my mom's favorite socks. We wear them with tennis shoes, Hey Dudes, and more. The fabric is incredibly soft and comfortable, they do not budge/fall in my shoe, and are extremely well made. I have become so attached to these socks, that I no longer want any other brand.
