This 90 mm CNC guide-scope ring combines an adjustable aluminium ring with a Vixen-style dovetail clamp. It supports guide tubes with an outside diameter of 45–80 mm.
The clamp attaches the ring to a compatible Vixen-style rail, allowing its position to be set along the rail. This product is one ring with a clamp; it is not a pair of guide rings.
Use the actual outside diameter of the guide tube when choosing the ring. The nominal 90 mm ring designation and the 45–80 mm usable tube range describe different dimensions. The published 135 g figure is identified as ring weight.
