Product Info for Zero Gravity Summit 30mm Ring

We set out to create a better scope clamping solution that could securely hold a scope without damaging the scope tube. The problem with using only two pieces to clamp 360 degrees around a tube is that there must be clearance allowed for assembly and material stretch under tension. (Example; The gaps on each side of most scope mounts.) As the rings are tightened compressing the scope tube, the scope tube takes the shape of the allowed space, deforming it. Consequently, the deformation of the scope tube affects the position and alignment of the lenses and components inside the scope, degrading the quality and clarity of the image.image

Using a three-piece design, we overlap each piece into the next creating a seamless contact area that maintains the scope tubes original shape. Having the rings come together at a single central point allows them to swing together evenly as they are torqued, eliminating the roll that makes setting up a scope in other mounts so tedious and time consuming.

Features of Zero Gravity Summit 30mm Ring

  • Stainless Steel Screw-Lock inserts are used for every fastener on the mount for a lifetime of trouble-free use. With these inserts, additional thread locking compound is not needed.
  • Flush mount rail clamps securely and repeatably attach the mount to the rail and avoid snagging on gear.
  • Two recoil lugs are machined into the base of the mount to transfer energy from the rifle to the mount without putting unnecessary load on the fasteners or clamps.
  • 7075 T-651 aluminum is used for the entire mount for maximum strength and durability, despite the added cost. 7075 aluminum features 150% of the shear strength of 6061 aluminum, and nearly 200% of the tensile strength.
