Magne-Tech 1"-38.5mm 3x Magnetic Ring Mount Part B Only (Female)
I love this "Part B" ring because it brings older or more traditional 1-inch tube optics into the modern, modular era. By having this female attachment ready on your scope, you aren't tied to a single rifle; the magnetic indexing allows you to snap a classic 1" glass onto any rail equipped with a Part A receiver. It’s the perfect way to ensure your favorite lightweight stalking scope can be swapped onto your primary rig in seconds without the need for tools or constant re-leveling.
Enhance your optics setup with a Magnetic Scope Mount from Magne-Tech, engineered for shooters who demand precision and adaptability. Combining advanced rare-earth magnetic technology with meticulous machining, this mount delivers secure, repeatable performance in any shooting environment. When paired with the Magne-Tech 3-Magnet Picatinny Rail Mount, it provides seamless integration for a stable and highly reliable platform.
The quick-detach functionality allows you to attach or remove your riflescope instantly without losing zero, making it ideal for transitioning between day, night and thermal optics. A patented magnetic mounting system works in conjunction with a dual-redundant locking system to keep your scope firmly secured, ensuring consistent accuracy shot after shot. With a return-to-zero capability within 0.25 MOA, you can confidently swap optics while maintaining dependable precision.
Machined from 7075-T6 billet aluminium and finished with MIL-A-8625 Type III hard coat anodising, this mount offers exceptional strength in a lightweight form. Designed to meet mil-spec standards, it withstands the rigours of tactical, competitive and hunting use. With extended mounting flexibility for optimal eye relief and broad scope compatibility, it is a versatile and robust solution for serious marksmen.

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.
