Product Information FIND OUT MORE
DESCRIPTION

The Arken Precision Cantilever Mount is designed for shooters who need additional forward scope placement while maintaining a strong, repeatable mounting platform.

CNC machined from 6061-T6 aluminium, the one-piece design helps keep both rings perfectly aligned while reducing the risk of movement under recoil.

With approximately 2.5 inches of forward extension and a 0 MOA configuration, it's well suited to general hunting, target shooting, pest control and range use where a level optical setup is preferred. 

The optic manufacturer's specification shall always supersede Arken's Rigid Precision mount specification, unless higher.

 

Height = 38.1mm

The main advantage of this mount is the forward extension. If you've struggled to achieve comfortable eye relief because your scope cannot move far enough forward in conventional rings, this mount provides additional adjustment range without needing rail extensions or alternative mounting solutions.

The one-piece construction helps keep both rings aligned from the factory, reducing installation issues and helping maintain consistent scope positioning. The 0 MOA design keeps the scope optically level with the rail, making it a sensible choice for general-purpose shooting where additional elevation bias is not required.

At 38.1mm high, it provides generous clearance for many medium and large objective scopes, although clearance will always depend on the rifle, rail height and scope dimensions.

Good For

  • 30mm tube rifle scopes
  • Air rifles with Picatinny rails
  • Rimfire rifles
  • Centrefire rifles
  • Target shooting
  • Hunting setups
  • Pest control rifles
  • Shooters needing additional forward eye-relief adjustment
  • Larger scopes requiring extra mounting flexibility

Not for

  • Compact scopes with less than 117mm between ocular and objective bells. 
  • 1-inch (25.4mm) , 34mm, 35mm scope tubes
  • 9-11mm dovetail rails without a suitable adapter
  • Shooters specifically seeking a 20 MOA long-range mount
  • Ultra-low mounting applications where minimal scope height is required

May not suit some older weaver rails where slot widths and spacing may vary. If the spacing varies then a 1 piece mount will normally not fit.

FREQUENTLY ASKED QUESTION(S)

Will this fit my scope?

This mount is designed specifically for scopes with a 30mm main tube.

What rail does it fit?

It is designed for MIL-STD Picatinny rails and will also fit many Weaver-style rails with compatible dimensions.

Will it fit a standard air rifle dovetail?

No. This mount does not directly fit 9-11mm dovetail rails. A suitable dovetail-to-Picatinny adapter would be required.

What does 0 MOA mean?

A 0 MOA mount keeps the scope level with the rail and does not add any built-in elevation angle. It is generally preferred for everyday hunting, pest control and target shooting distances.

Why would I choose a cantilever mount?

A cantilever mount moves the scope further forward than conventional rings, making it easier to achieve correct eye relief and a comfortable shooting position.

What height is the mount?

The listed height is 38.1mm (1.5 inches).

Is this a one-piece mount?

Yes. The mount uses a rigid one-piece design with integrated rings for improved alignment and strength.

Will it hold zero on higher-recoil rifles?

The CNC-machined aluminium construction and Picatinny cross-bolt attachment system are designed to provide a secure mounting platform. As with any mount, correct installation and torque settings are essential.

Does it come with a warranty?

The product listing states that Arken Optics provides a lifetime warranty on its optics products

MOUNT SIZE GUIDE
Ring Height Calculator
This calculator works out the minimum ring height (base-to-centre) you should use, including a tolerance allowance.
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.
Diagram showing where to measure the scope objective outer diameter

Measure the outermost diameter of your scope’s objective bell (including any flare).

Diagram showing where to measure scope cover thickness

Measure the thickness of any scope cover if used. If none, leave as 0.

Diagram showing where to measure rail to barrel clearance

Measure from the top of the rail to the highest point of the barrel.

Tolerance
We add a little extra clearance to account for real-world variation. Default is +1 mm.
Minimum Ring Height Needed: 0.00 mm (0.00 inches)

Enter your measurements above to calculate the lowest ring height (base-to-centre) you can realistically use.

Includes tolerance

Formula used: (A + 2×B) / 2 − C + T
Where A = objective outer diameter, B = cover thickness, C = rail-to-barrel clearance, T = tolerance.
