Use on any air gun, airsoft gun or firearm that has a Weaver or Picatinny rail.
UTG 30mm Max Strength Rings, Low, Weaver/Picatinny, Twist-Lock Base.The cross-slots help stabilize the rings so your scope or dot sight is rock-solid. Instead of working with several hex screws on each ring base, you just have to hand-tighten one twist-lock base screw on each ring and you're good to go. Also, the weight has been reduced by channeling out the center of each cap.
