30mm Weaver Rings with 1 Inch Inserts

30mm Weaver Scope Rings

This pair of NcStar scope rings clamps onto a Weaver rail, the flat-topped mounting rail with cross slots found on many rifles and shotguns. They are sized for a 30mm scope tube, and the included inserts step them down to hold a 1 inch tube. One set of rings covers both common scope sizes, which helps if you swap optics between guns or are still choosing a scope.

Features

• 30mm Ring Diameter — Each ring is cut to hold a 30mm main tube, a size used on many modern riflescopes.
• 1 Inch Inserts Included — The inserts sit inside the rings and reduce the diameter so a 1 inch scope tube is held securely.
• Weaver Base Mount — The base clamps across a Weaver-style rail, the slotted rail system used on many rifle receivers and scope bases.
• Thumb Nut Clamp — A knurled thumb nut on the cross bolt tightens each ring to the rail by hand.
• High See-Through Design — An open window under each ring raises the scope and leaves a sight line beneath it.
• Split Ring Caps — Each ring separates into a top cap and lower half, so the scope drops into place and the cap closes over it.
• Sold As A Pair — Two matching rings come in the set to support the scope at the front and rear of the tube.
• Black Textured Finish — The rings have a matte black, lightly textured finish that suits most rifle and scope colors.

Fit And Mounting

Check two things before ordering: your scope's tube diameter, which should be 30mm or 1 inch, and that your rifle has a Weaver-style rail or base. Each ring opens at the cap, and the base locks to the rail with its thumb nut, so you can do the initial mounting without a dedicated tool. The high, see-through profile gives large objective lenses room over the barrel and keeps a view open below the scope.
