ASToptics CNC Guide Scope Ring 127 mm with Vixen Clamp

ASToptics CNC Guide Scope Ring 127 mm with Vixen Clamp

This 127 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 65–115 mm.

Mounting and configuration

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.

Size selection

Use the actual outside diameter of the guide tube when choosing the ring. The nominal 127 mm ring designation and the 65–115 mm usable tube range describe different dimensions.

Compatibility notes

Single ring with clamp confirmed in manufacturer description. The table lists 370 g as 2 × 185 g despite the single-ring package; no complete-assembly weight is inferred from this conflicting pair figure.
