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.
