.177 / 4.5mm – 13 shot capacity


The new magazine has an all-metal construction. It features a flip-open gate that makes loading pellets into the drum’s chambers quick and easy. A small magnet ensures the gate stays in the correct position when closed, improving pellet-to-breech feed. This ensures unrivalled levels of accuracy, often a fault with magazine-fed air rifles. This makes the new BRK-Brocock magazine suitable for hunting and target use.

Note that the XR version of the new SI magazine inserts/extracts from the right side of the breech only.


The Brocock Self Indexing Magazine works with rifles using a different pellet feed probe from older models. This style mag is therefore not back-compatible with the older-style, bolt-action Brocock rifle models fitted with an ‘indexing’ probe. However, the new-style probe can be purchased separately here to convert bolt-action rifles to the new Self-Indexing system.
