Tier One 30mm Long Saddle High (38mm) FLAT 1 Piece Monomount
The Tier One 30mm Long Saddle High (38mm) FLAT 1 Piece Monomount is precision machined from a single billet of 7075T6 aluminium using advanced 5-axis CNC technology for exceptional strength and accuracy. Its one-piece construction and large clamping area provide maximum stability under heavy recoil, while the Mil-Spec hard anodised finish ensures long-lasting durability. Featuring a built-in Anti-Cant bubble, Mirage Band compatibility and supplied levelling wedge, this premium mount is designed for precise optic alignment and reliable performance in the field.
The Tier One 30mm Long Saddle High (38mm) FLAT 1 Piece Monomount is a premium precision scope mount engineered for shooters who demand exceptional accuracy and durability. Manufactured from a single billet of high-grade 7075T6 aluminium using advanced 5-axis CNC machining, this true one-piece mount delivers outstanding strength and repeatable precision in even the most demanding conditions.
By reducing the machining process from eight operations to just two, Tier One ensures there is no loss of accuracy caused by re-setting between operations. All critical faces are machined in a single process to maintain the highest tolerances and provide superior optic alignment for improved downrange performance. The 38mm High configuration and Long Saddle design offer excellent compatibility with larger optics and extended mounting requirements.
Built to withstand heavy recoil, the Monomount features a large scope clamping area for maximum stability and secure retention. A durable Mil-Spec 30 micron hard anodised finish provides long-lasting protection, while the integrated Anti-Cant bubble helps maintain perfect rifle levelling for consistent shot placement. The mount is also Mirage Band compatible and supports optional accessory rails for added versatility.
Every detail, including the stainless steel screws, is precision machined in-house to ensure uncompromising quality. Supplied with a levelling wedge for true bore-to-reticle alignment, the mount comes complete in a hard plastic case with the necessary Torx bits for straightforward installation.

What are the key benefits of Tier One mounts?
-The mounts are produced on 5-axis CNC machinery, going from a solid billet to a finished item in one operation. This removes accuracy losses caused by resetting the workpiece in different machines. They are manufactured to 3-micron tolerances, eliminating the need for lapping when installed on a quality rail.

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.
Measure the outermost diameter of your scope’s objective bell (including any flare).
Measure the thickness of any scope cover if used. If none, leave as 0.
Measure from the top of the rail to the highest point of the barrel.
We add a little extra clearance to account for real-world variation. Default is +1 mm.
Enter your measurements above to calculate the lowest ring height (base-to-centre) you can realistically use.
(A + 2×B) / 2 − C + TWhere A = objective outer diameter, B = cover thickness, C = rail-to-barrel clearance, T = tolerance.
