Magne-Tech 34-38.5mm 3x Magnetic Ring Mount Part B Only (Female)
Protect your investment in high-end glass with the Magne-Tech 34-38.5mm Magnetic Ring Mount (Part B Only). This female ring mount is the perfect addition for shooters who have invested in multiple 34mm optics and want to share them across a single Magne-Tech-equipped rifle. Avoid the mechanical wear and tear of traditional screw-down mounts and enjoy the efficiency of a magnetic interface. Crafted for durability and extreme accuracy, this mount provides a consistent 0.25 MOA return-to-zero, ensuring your 34mm professional optics perform exactly as intended, shot after shot, without the hassle of constant re-zeroing. - George
The Magne-Tech 34–38.5mm 3x Magnetic Ring Mount Part B Only (Female) from Magne-Tech is engineered for shooters who demand precision, speed and adaptability. Utilising advanced rare-earth magnetic technology, this ring mount delivers secure, repeatable performance when paired with the Magne-Tech 3-Magnet Picatinny Rail Mount. Its quick-detach functionality enables rapid attachment and removal of your riflescope without losing zero, making it ideal for transitioning between day, night and thermal optics.
Designed with accuracy in mind, the mount features a patented magnetic mounting system combined with a patent-pending dual-redundant locking system, ensuring your optic remains firmly secured under recoil and demanding conditions. With a return-to-zero capability within 0.25 MOA, shooters can confidently remove and refit their scope while maintaining consistent point of impact.
Machined from 7075-T6 billet aluminium and finished with MIL-A-8625 Type III hard coat anodising, this ring mount offers exceptional strength in a lightweight form. Built to meet mil-spec standards, it withstands the rigours of tactical, competitive and hunting applications, while its extended mounting design allows precise scope positioning for optimal eye relief and enhanced versatility.

1. How reliable is the "Return-to-Zero" when swapping optics? Magne-Tech systems are engineered for surgical precision, offering a guaranteed return-to-zero within 0.25 MOA. Because the system uses three high-strength magnetic contact points to guide the mount into a consistent, repeatable position, you can swap between a day scope and a thermal unit (or between different rifles) without the need for a trip to the range to re-zero.
2. Will the magnets hold up under heavy recoil from large caliber rifles? Absolutely. While the magnets provide the initial "snap" and alignment, the system features a patented dual-redundant locking mechanism. The rare-earth magnets offer over 15 lbs of retention on their own, but the mechanical locks ensure the optic remains rock-solid even under the violent recoil of magnum calibers or during rugged tactical maneuvers.
3. What is the difference between "Part A" and "Part B"? Think of it as a plug and a socket:
-
Part A (Male/Receiver): This is the base that stays permanently attached to your rifle's Picatinny rail.
-
Part B (Female/Ring Mount): This is the ring set that stays attached to your scope tube (available in 1", 30mm, or 34mm).
-
To use the system, you need at least one of each. If you have one rifle but three different scopes, you would buy one Part A and three Part B mounts.
4. Are these mounts heavy? I’m worried about adding bulk to my setup. Despite their strength, Magne-Tech mounts are surprisingly lightweight. They are CNC-machined from 7075-T6 billet aluminum—the same high-grade alloy used in aircraft and high-end receivers. This provides the durability of steel at a fraction of the weight, and the MIL-A-8625 Type III hard coat anodized finish ensures they are scratch and corrosion-resistant.
5. Can I use a 30mm "Part B" ring with a 34mm "Part A" receiver? Yes! One of the best features of this system is its universal compatibility. As long as you are using the 38.5mm height series, the Part A receiver base is the same across the board. You can swap a 1" scope, a 30mm scope, and a 34mm scope onto the exact same Part A base on your rifle without any compatibility issues.
