-Nathan (Technical Advisor)
A solid one-piece scope mount designed for air rifles and rimfire setups using standard 9–11mm dovetail rails. The key feature here is built-in droop compensation, helping you achieve a proper zero when your scope runs out of adjustment.
This is a common issue on air rifles with barrel droop, where the point of impact sits too low even at maximum elevation. This mount corrects that at the base level.
The key difference is the built-in vertical taper (approx 0.75mm / 20 MOA).
This effectively angles the scope slightly downward, allowing:
- More usable elevation adjustment
- Easier zeroing at longer distances
- Better setup on rifles with barrel droop
Without this, many setups run out of adjustment before achieving a proper zero.
Scope Fit & Height Guide (Important)
- Base to ring bottom: approx 19mm
- Base to ring centre: approx 31mm
What this means in practice:
Will comfortably clear scopes up to approx 60mm outer objective diameter (on a flat rail setup)
Typical fit guidance:
- 40mm AO scopes - fits
- 50mm non-AO scopes - fits
- 50mm AO scopes - Will not fit unles base is rasied
Note: Actual clearance depends on barrel profile and rail height, but this gives a reliable working guide.
Height = 31.7mm
- A: 19mm
- B: 120mm
- Weight: 142g
