1 Inch Weaver Rings

1 Inch Weaver Scope Rings

The NcStar RB01 is a pair of scope rings that holds a riflescope with a 1 inch main tube on a Weaver-style rail. Weaver rails are the flat-topped bases with cross slots found on many rifles, shotguns and airguns. These rings are a simple, low-cost way to put a standard 1 inch scope on a gun that already has one. Hunters, plinkers and anyone setting up a budget optic will find them a straightforward fit.

Features

• 1 Inch Tube Diameter — Sized for riflescopes with a 1 inch main tube, the most common size on traditional hunting and rimfire scopes.
• Weaver Rail Base — The clamp grips a Weaver-style rail, and Weaver rings generally fit Picatinny rails as well.
• Thumbscrew Clamp — A large knurled thumbscrew tightens each ring onto the rail, so you can mount and remove them by hand.
• Split Two-Piece Rings — Each ring separates into a top cap and a base, which lets you lay the scope in place instead of sliding it through.
• Screw-Secured Caps — The top cap fastens to the base with screws on both sides for even pressure around the scope tube.
• Sold As A Pair — Two rings come in the set, which is what a standard scope needs for front and rear support.
• Matte Black Finish — A non-reflective black finish matches most scopes and rifles and keeps glare down.

Fit And Compatibility

Check two things before ordering: your scope needs a 1 inch main tube, and your rifle needs a Weaver-style or Picatinny rail. Scopes with 30mm or larger tubes will not fit these rings. The cross-slot clamp sits in a rail slot to stop the rings from sliding under recoil, and the split caps let you adjust eye relief and level the reticle before you tighten everything down.
