Monstrum Precision V2 Picatinny Scope Rings with Integrated Level Bubble | 30 mm Diameter | Medium Profile

  • The adjustable height design of WH201 scope rings allows the shooter to find the most suitable and comfortable height of scope, position the center of the riflescope tube at a height of 32mm(1.26") to 38mm(1.5") from the base, fits 1 inch and 30mm tube optics.
  • As compensation for Elevation adjustment of the scope, a minimal adjustment scale is 1 mm(It is recommended that the height difference be no greater than 1 mm), and the corresponding adjustment amount of 100 yards is 20MOA.
  • The double screw structure at the bottom maximized the stability of the whole optical system, but it will only work with Picatinny rails—will not work with Weaver rails. Quick installation and disassembly can be realized by hand.
  • Precision CNC machined from 6061 T6 aircraft-grade aluminum and finished in a colorful anodizing for unique appearance, passed rigorous accuracy and stability tests.
  • Disadvantage and Warranty: Due to the different lighting environments, there are slight differences between real objects and pictures. We provide a lifetime warranty for this product.
