The UTG ACCU-SYNC Cantilever Mount with 30 MOA is the 34 mm version for long-range scopes on Picatinny. 70 mm offset, QR lever, and a defined one-piece ring geometry combine cantilever, eye relief, and quick detachment in one mount.

34 mm tube size and 30 MOA both have to match
The 30 MOA incline shifts the usable elevation adjustment range; the 34 mm ring diameter determines the physical fit. Neither is interchangeable or “almost fitting.”

for 34 mm main tubes
30 MOA / approx. 0.5° cantilever
70 mm cantilever offset
60 mm inner and 85 mm outer ring spacing
80 mm base length, 25 mm ring width
Locking QR lever and squared recoil stops
6061-T6 aluminum, matte black anodized


Before purchase: check 34 mm tube, objective outer diameter, ring spacing, turret section, and zero distance. 30 MOA must not cause the scope to already reach its lower adjustment limit at the desired base distance.
Our assessment
For a deliberately built 34 mm long-range optic, the combination of 30 MOA and 70 mm offset is coherent. For light hunting or neutral all-round setups, it is often too specialized.

Practical tip: Determine the internal elevation adjustment range of the optic before mounting. Only then adjust eye relief and QR lever. After the first training, check the ring caps and lever tension according to the manufacturer’s instructions.
Technical classification

Tube diameter: 34 mm
Cantilever: 30 MOA
Offset: 70 mm
Base: Picatinny QR
Material: 6061-T6 aluminum

Is the mount suitable for 30 mm tubes? No. The ring mount is precisely designed for 34 mm. When is 30 MOA useful? When the existing elevation adjustment range is deliberately extended for longer distances and the close zero remains achievable. Conclusion: A well-thought-out 34 mm QR mount for planned long-range setups with moderate to significant cantilever.
