BRK Brocock Quantum Hi-Capacity Magazine

Extra Shot Payload in ‘Snail Mag’ format

The BRK Brocock Quantum Hi-Capacity Magazine is an official factory Performance Center upgrade for various PCP air rifle models (see below). It extends the rate of fast-fire by offering a high-shot payload and is especially useful for hunters and pest controllers who do not have time to keep reloading.

Design

This factory-original magazine is designed around the ‘snail mag’ format – a name derived from its look. It provides a greater shot-capacity than the standard magazine. However, it retains the simplicity of a gate-opening loading system.

The new Quantum uses a localised, two-gear drive system with a cam-guided motion. As its primary gear rotates, it automatically engages the secondary gear, ensuring a perfectly synchronized feed of ammo.

Additionally, the new Quantum introduces the ‘Link 8’ concept – a horizontal figure-of-eight carrier system. Individual carrier pairs interact dynamically depending on their position within the magazine’s cycle, ensuring jam-free operation and perfect alignment when finally presented to the breech / bore of the rifle. This results in no loss of accuracy compared to single-shot feed.

Construction

BRK Brocock has always been at the forefront of airgun R&D, and this magazine is engineered using the latest 3D Composite Printing Technology.

3D Printing – or Additive Manufacturing – is the construction of a three-dimensional object from a computer-generated, digital design. This state-of-the-art manufacturing process is now incorporated into many world-leading industries, such as in aerospace and Formula 1 motorsport. It is therefore a natural choice for BRK Brocock’s class-leading airguns, like the Ghost, XR and XR2 Series.

Caliber Availability

Our extended capacity mag is available in four calibers. The shot-capacity varies according to the caliber, as follows:

• .177″ / 4.5mm – 30 shots
• .22″ / 5.5mm – 28 shots (Ghost fit)
• .22″ / 5.5mm – 26 shots (XR / XR2 fit)
• .25″ / 6.35mm – 24 shots
• .30 / 7.62mm – 22 shots

Fitting and Compatibility

For the BRK Ghost rifle, the magazine can be inserted into the breech from either the right-hand side, or left-hand side. For XR and XR2 models, the fit is left-hand only. To ensure the rifle shoots with maximum precision, we have designed these Hi-Capacity magazines to be rifle model specific (please select model at checkout). Currently, there are magazines to fit the following BRK Brocock precharged pneumatic (PCP) air rifle models:

• Ghost (all model variants)
• XR / XR2 Series (all model variants)

Note: The BRK Ghost magazine will also fit the Daystate Alpha Wolf and Delta Wolf electronic PCP air rifles; the XR2 version will also fit the Daystate Blackwolf PCP air rifle. In .22 / 5.5mm caliber, shot capacity is either 28 or 26, according to fit type.

.177 Quantum Magazine Pellet Compatibility

The .177 Quantum Magazine has been tested and confirmed to function reliably with Rangemaster Sovereign Hunter 10.3gr pellets.

Other pellet types may also be suitable; however, Rangemaster Sovereign 8.44gr and JSB Exact 8.44gr pellets are not recommended, as they may cause loading issues.
