Vector Victoptics ACD Screw Mount 25.4mm (1") 9-11mm Dovetail Mounting Rings - Medium
The Vector Victoptics ACD Screw Mount 25.4mm (1") 9–11mm Dovetail Mounting Rings – Medium is basically the balanced “middle-ground” option in this dovetail ring series, giving you a bit more clearance than low mounts while still keeping a stable, low recoil-friendly setup. It’s CNC-machined from 6063-T6 aluminium with four-screw clamping per ring, so it grips firmly onto 11mm (9–11mm) dovetail rails commonly found on air rifles and rimfires. The medium height sits at about 27mm from base to scope centre, which is ideal if low rings are too tight but you still don’t want the scope sitting too high.

1. What tube size does it fit?
It fits 1 inch / 25.4mm scope tubes.
2. What rail does it mount to?
It’s designed for 9–11mm dovetail (3/8") rails, typical on air rifles.
3. What does “medium height” mean here?
The centre height is about 27mm, giving more clearance than low rings while staying fairly close to the barrel.
4. What is it made from?
It’s made from 6063-T6 aluminium alloy, CNC-machined for strength and consistency.
5. How many screws hold the scope?
Each ring uses 4 screws, helping distribute pressure and reduce slipping under recoil.
6. Is it suitable for real firearms?
Yes, but it’s most commonly used on air rifles and low-recoil platforms due to the dovetail system.
7. Does it hold zero well?
Yes—when properly tightened, it’s designed to stay stable and maintain alignment.
8. Why choose medium instead of low?
Medium gives you extra clearance for larger scopes or awkward barrel/magazine setups without going overly high.
9. Is it quick-detach?
No, this is a fixed screw-down mount, not QD.
10. What’s the downside?
Dovetail mounts are less universal than Picatinny and can vary slightly between rifles, so fitment matters more.

Please note: All clearance calculations are based on mounts with 0 MOA. While MOA can be factored in, actual clearance may vary due to variables that can't always be accurately calculated. If you're considering an MOA mount and are unsure about the required height, we recommend contacting our sales team directly.
Measure the outermost diameter of your scope’s objective bell (including any flare).
Measure the thickness of any scope cover if used. If none, leave as 0.
Measure from the top of the rail to the highest point of the barrel.
We add a little extra clearance to account for real-world variation. Default is +1 mm.
Enter your measurements above to calculate the lowest ring height (base-to-centre) you can realistically use.
(A + 2×B) / 2 − C + TWhere A = objective outer diameter, B = cover thickness, C = rail-to-barrel clearance, T = tolerance.
