Magne-Tech 34x38.5mm 3x Magnetic Ring Mount Part B Only (Female)

The Magne-Tech 34×38.5mm 3× Magnetic Ring Mount (Part B – Female) is a precision-engineered quick-detach riflescope mounting component designed for hunters and precision shooters who require secure optic retention, repeatable alignment and convenient scope interchangeability.

Designed specifically for riflescopes with a 34mm main tube diameter, this female ring assembly pairs with Magne-Tech's separately available 3-Magnet Magnetic Locking Picatinny Rail Mount Receiver (Part A – Male) to create a complete magnetic quick-detach mounting system.

When installed with the compatible male receiver, the system positions the riflescope centreline 38.5mm above the Picatinny rail, providing an elevated mounting profile and flexibility for suitable eye relief.

Featuring Magne-Tech's patented magnetic mounting technology, the system allows compatible riflescopes to be quickly attached, removed and reinstalled while maintaining repeatable positioning. The complete assembly incorporates a dual-redundant mechanical locking mechanism to provide additional retention alongside the magnetic connection.

Precision-machined from 7075-T6 billet aluminium and finished with MIL-A-8625 Type III hard-coat anodising, the mount offers excellent strength, durability and resistance to wear.

Ideal for users who already own a Magne-Tech three-magnet receiver, this female ring mount provides a convenient way to prepare additional 34mm riflescopes for quick interchangeability.

Key Features

• Magnetic Quick-Detach System: Allows convenient removal and reattachment when paired with a compatible Magne-Tech three-magnet male receiver.

• 38.5mm Centreline Height: Positions the scope tube centreline 38.5mm above the Picatinny rail when assembled with the matching receiver.

• Three-Magnet Mounting Interface: Designed to engage with Magne-Tech's patented rare-earth magnetic receiver system.

• Dual-Redundant Locking System: The complete mounting assembly incorporates mechanical locking for additional retention.

• Precision Return-to-Zero Design: Engineered for consistent alignment through repeated mounting cycles, with manufacturer laboratory testing reporting a maximum measured shift of 0.25 MOA.

• 7075-T6 Aluminium Construction: Precision-machined high-strength aluminium provides excellent structural durability.

• Type III Hard-Coat Anodising: MIL-A-8625 Type III surface treatment improves resistance to abrasion, corrosion and wear.

• Extended Mounting Geometry: Provides flexibility in riflescope positioning for suitable eye relief.

• Lightweight Construction: Manufacturer-listed weight of 6.5 oz (approximately 184g).

• Modular Optic Compatibility: Enables multiple compatible female-mounted riflescopes to share a matching Magne-Tech male receiver.

• Picatinny Compatibility: Connects to compatible MIL-STD-1913 Picatinny rails through the separately available receiver.

Technical Specifications

Magnetic Quick-Detach Technology

Magne-Tech's innovative mounting system combines rare-earth magnetic technology with precision-machined mating surfaces to provide consistent positioning.

The Part B female ring mount remains securely attached to the riflescope, while the separately available Part A male receiver remains installed on the rifle's Picatinny rail.

When joined, the three-magnet interface helps guide the components into position, while the mechanical locking system provides additional retention.

This modular design allows compatible riflescopes to be quickly detached and reattached without repeatedly loosening the Picatinny receiver hardware.

Return-to-Zero Performance

Magne-Tech's magnetic mounting technology is engineered to minimise optical alignment changes during repeated removal and reattachment.

In manufacturer laboratory testing using co-witnessed lasers, the magnetic scope mounting system demonstrated a maximum measured alignment shift of 0.25 MOA after hundreds of attachment cycles.

Actual point-of-impact consistency depends on the complete mounting configuration, rifle, optic, installation and operating conditions.

For consistent performance, ensure both mounting components are correctly installed and verify the rifle's zero following changes to the mounting configuration.

Compatibility

The Magne-Tech 34mm Magnetic Ring Mount is designed for:

• 34mm Main Tube Riflescopes: Compatible hunting, sporting and precision riflescopes.

• Magne-Tech 3-Magnet Picatinny Receiver (Part A – Male): Required to complete the magnetic mounting assembly.

• Picatinny-Equipped Rifles: Suitable rifles using the matching receiver on a MIL-STD-1913 Picatinny rail.

• Modular Magne-Tech Scope Mount Systems: Allows additional compatible 34mm scopes to be prepared for interchangeability.

This mount is specifically designed for 34mm scope tubes and does not directly fit 30mm or 1-inch tubes.

Installation Specifications

Ring Mount Screw Torque: 15 in-lb.

The female ring assembly secures around the riflescope's 34mm main tube using the supplied fasteners.

Correct ring positioning and the manufacturer's specified tightening procedure are important for secure mounting and preventing damage to the riflescope tube.

The separately available male Picatinny receiver has its own installation requirements.
