Vector Optics 30 mm Adjustable Cantilever Dovetail Rings GenII – High‑Profile Mount for Dovetail Rails
The Vector Optics 30 mm Adjustable Cantilever Dovetail Rings GenII (model XASR‑3065) provide a professional‑grade mounting platform for scopes with 30 mm main tubes on 11 mm dovetail rails. Featuring adjustable elevation (35–41 mm), smooth angled compensation, and a forward cantilever design, these rings are ideal for rimfire rifles, airguns, or classic platforms needing extended eye relief and precise ballistic alignment. Manufactured from CNC‑machined 6061‑T6 aluminum with matte matte‑black anodizing, they deliver strength and stability in lightweight form.:contentReference[oaicite:0]{index=0}
Main Benefits & Functional Features
- Adjustable Elevation Height: Easily set the optic center height between 35 mm and 41 mm (1.4–1.6 in) to accommodate various objective lens profiles and cheek weld preferences.:contentReference[oaicite:1]{index=1}
- Angle Compensation: Finely adjustable tilt allows shooters to align the tube angle to optimize ballistic drop compensation without altering turret zero.:contentReference[oaicite:2]{index=2}
- Cantilever Mounting: Extends the scope forward from the rail, creating rail space for accessories and providing ergonomic eye relief. Particularly beneficial on shorter dovetail bases.:contentReference[oaicite:3]{index=3}
- Secure Dovetail Interface: Fits 11 mm dovetail rails with anti‑retreat pin and uses four robust cross‑bolts per ring to prevent movement during recoil.:contentReference[oaicite:4]{index=4}
Real-World Use Cases
Perfect for high‑precision air rifle shooters, rimfire hunters, and rifle platforms where rail length is restricted. The adjustable height allows mounting scopes with large objectives without interference—while the cantilever offset ensures a comfortable shooting position without sacrificing zero integrity.
Whether shooting from a bench rest or in the field on vintage dovetail rifles, these rings offer ergonomic placement and improved mechanical alignment for consistent performance.
