• Cantilever 70 mm / 2.76”
• Color Black Hardcoat Anodized
• Height 32 mm
• Quick Release No
• Rail/Type Picatinny
• Tilt 0 MIL / 0 MOA
• Tube Diameter 34 mm

• Monolithic one‑piece construction - CNC‑machined from a single billet of aerospace‑grade aluminium to eliminate tolerance stacking, flex, and ring misalignment common in multi‑piece mounts.

• High‑rigidity structural geometry - Optimised cross‑section and material distribution provide exceptional torsional and vertical stiffness, maintaining optic alignment under heavy recoil and dynamic loading.

• Hard‑anodised surface treatment - Type III hard anodising delivers excellent abrasion resistance, corrosion protection, and a non‑reflective tactical finish.

• Diagonal ring split design - Improves load distribution around the scope tube while keeping elevation and windage turrets fully accessible, preventing obstruction during adjustment.

• Integrated scope levelling system - Built‑in bubble level allows the shooter to reference rifle cant and optic alignment directly on the mount for precise long‑range shooting.

• Multi‑axis accessory interface -  Machined mounting points on multiple faces of the mount support direct attachment of optical and electronic accessories without adding separate rails.

• Low‑profile accessory mounting - Keeps mounted devices close to the bore axis and centre of mass, preserving rifle balance and minimising parallax and offset errors.

• Precision‑cut recoil lugs and rail interface - Provides repeatable, slip‑free engagement with Picatinny rails for consistent return‑to‑zero performance.

• High‑strength fastener system - Torque‑optimised fasteners maintain clamping force under vibration and recoil, preventing optic movement or zero shift.

• Designed for extreme‑range precision - Engineered to support the mechanical and optical demands of ELR, PRS, and professional long‑range shooting platforms.

Why was this mount designed lower than most cantilever mounts?

The lower profile is intended to create a more consistent cheek weld and reduce vertical head movement while aiming. Even small variations in head position can cause vertical shot dispersion, especially when shooting at distance. A lower optical axis also reduces mechanical offset, which improves accuracy at shorter engagement distances.

Does the lower mounting height make eye relief harder to set correctly?

Not necessarily, because the cantilever design still moves the optic forward relative to the receiver. What changes is the head position required to maintain a full sight picture, which actually encourages more consistent positioning. Over time, shooters often find this improves repeatability rather than making setup harder.

How does the one‑piece construction improve zero retention compared to separate rings?

With separate rings, small misalignments can occur due to rail tolerances or uneven tightening, which can introduce stress into the scope tube. A one‑piece mount eliminates that issue by keeping both rings perfectly aligned from the factory. This reduces movement under recoil and significantly improves long‑term zero stability.

Why would someone choose this mount instead of a higher one?

Shooters who prefer a more natural head position or a lower cheek weld often find a lower mount more comfortable and repeatable. It also reduces the amount of “floating” head movement that can occur with higher mounts. For precision shooting, especially at longer distances, that small improvement in consistency can make a noticeable difference.

How does the cantilever design affect recoil performance?

The forward positioning of the optic shifts weight slightly toward the front of the rifle. This can improve recoil tracking by reducing the tendency for the rifle to lift excessively after the shot. Better recoil tracking helps shooters stay on target and observe their own impacts.

How important is torque consistency when installing this mount?

Torque consistency is extremely important because uneven tightening can create pressure points on the scope tube. These pressure points can cause minor alignment issues that affect tracking accuracy. Using a torque tool helps ensure the optic sits perfectly straight and remains stable over time.

Does the lower height improve performance at short distances?

Yes, because a lower optical axis reduces the difference between where the barrel is pointing and where the optic is aiming. At short range, this mechanical offset can affect point of impact more than many shooters realize. A lower mount helps reduce that difference and improves close‑range precision.

Does this mount help maintain consistent eye alignment?

Yes, because the lower mounting height encourages a more repeatable head position. When your eye returns to the same position behind the optic every time, the sight picture becomes more consistent. That consistency directly affects accuracy and shot placement.

How does it compare to traditional two‑piece ring setups?

Two‑piece ring setups rely heavily on perfect rail alignment, which isn’t always guaranteed. A one‑piece mount removes that risk by keeping everything perfectly aligned from the start. This improves reliability and reduces the chance of long‑term alignment issues.

Will the mount hold zero if the rifle is transported frequently?

Yes, the rigid design and precise rail engagement help maintain zero even if the rifle is moved regularly. Many shooters worry about zero shift during transport, but a strong one‑piece mount significantly reduces that risk. As long as the mount isn’t removed, the zero should remain stable.

Does the mount reduce vibration from recoil?

It doesn’t eliminate vibration, but it does reduce how much of that vibration affects the optic. A rigid mount absorbs and distributes recoil forces more evenly than lightweight or flexible mounts. This helps protect both the optic and the zero.

How does the mount help maintain consistent shot placement?

Consistency comes from repeatable head position and stable optic alignment. When the optic stays perfectly aligned and the shooter’s eye position remains consistent, shot placement becomes much more predictable. Even small improvements in consistency can make a big difference over time.

Does the mount help protect the scope from damage?

Yes, because even pressure around the tube reduces the chance of internal damage caused by uneven clamping. High‑quality optics are sensitive to mounting pressure, so a well‑designed mount helps extend their lifespan. This is especially important for expensive scopes.

Is it suitable for shooters who prioritize precision over speed?

Yes, especially if they prefer a lower optic height. A lower mount often improves consistency, which is more important than speed for precision shooting. Many precision shooters prefer this style for that reason.

Will it improve accuracy compared to a cheaper mount?

In many cases, yes. Cheaper mounts are more likely to flex slightly under recoil or apply uneven pressure to the scope tube. A stronger mount reduces those issues and helps maintain consistent accuracy over time.

How does the mount support repeatable shooting technique?

It encourages the shooter to maintain the same head position and cheek weld every time they aim. That consistency makes it easier to build a repeatable shooting technique. Over time, this leads to better accuracy and tighter groupings.

Why would experienced shooters prefer this mount?

Experienced shooters often notice small alignment and consistency differences that beginners may not. A well‑designed mount helps maximize the performance of both the rifle and the optic. That makes it particularly appealing to shooters who want the most consistent results possible.
