ZCO manufactures their rings are CNC machined in-house out of 7075 aluminum for durability and hard coat anodized for wear and abrasion resistance. Individual Picatinny rings allow for easy positioning of the scope to set proper eye relief. ZCO also manufactures alternate top ring caps to enhance the capabilities of the mounting system. A cap with an integrated folding bubble level (mountable on left or right side) as well as a mounting location for a short or long rail section. This would allow a secondary red dot sight or laser rangefinder to be mounted.
With ZCO’s unique 36mm tube width, it is often hard to find just the right set of rings. Here, we have “made for it” rings in 36mm by ZCO, made in Austria.
