ZCO manufactures their rings CNC machined in-house out of 7075 aluminum for durability and hard coat anodized for wear and abrasion resistance. This cap works with the Picatinny rings. An integrated folding bubble level is mountable on left or right side. On top is a mounting location for a short or long rail section (not included). This would allow a secondary red dot sight or laser rangefinder to be mounted.
