TSR "W" Rings from TPS are precisely machined from aluminum billet, with tolerances held to .0002" to provide maximum scope/ring contact. They hold scopes securely against heavy recoil. The four-screw cap lets you align the reticle; tighten the left side of the cap, then the right side without the scope rotating. The radiused edges and corners help prevent snagging while providing attractive appearance and the large clamp-nut lets you torque the rings to Weaver or Picatinny bases.
CHOOSING RINGS: Ring height is determined by measuring the outside objective (bell) diameter on your scope.
Ring Height: .356" (measured from base of ring to bottom of scope tube)
