Vortex · 34 mm · 20 MOA
Precision Extended Cantilever Mount: Only buy cantilever with elevation if your system really uses it This 34 mm mount combines 2 inch offset, 20 MOA mechanical elevation, 40 mm centerline height and 7075-T6 aluminum. The relevant point is not the buzzword “Long Range,” but whether zero, internal elevation travel and desired distances fit the elevation.


Our honest assessment

20 MOA does not create additional clicks. The mount changes the mechanical baseline of the scope and can thus provide more usable elevation travel towards long range. At the same time, the optic must still have enough downward travel to zero cleanly at the desired zero distance.
The 40 mm centerline also affects head position and cheek weld. That’s why elevation and height belong in the same buying decision.



Fits well if … … your scope has a 34 mm main tube and the 20 MOA elevation fits zero and elevation adjustment range mathematically.
… you are looking for a robust cantilever mount made of 7075-T6 with 2 inch offset.


Fits less well if … … you buy 20 MOA just because of the label without checking the available elevation travel of the optic.
… 40 mm centerline height would worsen your desired head and cheek weld position.


Features and practical effect


20 MOA elevation Shifts the mechanical baseline of the scope. This can be valuable at long distances but must fit the zero.


3
4 mm tube diameter Only for scopes with the corresponding main tube. Objective diameter or outer diameter of the turrets are not relevant for this.


40 mm Centerline Determines the optical axis height above the base and affects stock fit, head position, and possibly accessory clearance.


7075-T6 / 2 inch offset Robust design with forward offset for suitable platform and eye relief geometries.


Avoid limits, disadvantages, and bad purchases

20 MOA is not a blanket precision improvement. Without the appropriate elevation adjustment range, the forward tilt can unnecessarily complicate achieving the desired zero.
Do not guess torque specifications. Existing product data show contradictory manufacturer information regarding base torque values. Therefore, no base number is given here: the current product manual and mounting markings are decisive.

Technical data with practical interpretation


Main tube / forward tilt 34 mm / 20 MOA – check both separately before purchase.


Tube center height 1.574 inch / 40 mm – relevant for head position and mechanical clearance.


Weight 197 g / 6.94 oz – robust precision class, not optimized for minimal weight.


Material / finish Precision machined 7075-T6 with Type-3 low-glare matte black.


Forward offset 2 inch – provides additional room for positioning the scope.


Ring caps 15–18 in-lbs according to existing manufacturer specifications; use only the current manual for the mounting base.


Scope of delivery and mounting note
Delivered is the Vortex Precision Extended Cantilever Mount 34 mm / 20 MOA. Before mounting, check main tube diameter, base interface, desired axis height, and zero planning. Tighten screws gradually and according to the current manufacturer instructions.
FAQ
What do 20 MOA do? They change the mechanical starting position of the optic and can provide more usable elevation travel for longer distances. Does the mount fit every scope? No. The main tube must be 34 mm; additionally, base, space requirements, and desired build height must fit the system. Why is the 40 mm centerline important? It determines the optical axis height and affects head position, cheek weld, and clearance. Should I choose 20 MOA as a precaution? Not without checking. First consider zero, internal elevation travel, and planned distance range, then decide.
Black Raptor · Avoid bad purchases
The Precision 34 mm / 20 MOA is a targeted system component, not a universal upgrade. If tube diameter, build height, forward offset, and elevation travel fit together, it makes sense. If any of these points are open, they should be checked carefully before purchase.
