BB Guns Extra Mags

Compatibility Comes First

Match each mag to your specific pistol or rifle family :

• 1911: 1911 CO2 Blowback Steel BB Magazine
• Glock-style: Glock 17 Gen4 18rd BB Magazine
• Beretta: KWC 92FS CO2 Blowback Steel BB Magazine

Leading manufacturers like Umarex and KWC design many of the OEM and licensed magazines in this category, and some families share cross-compatibility across series.

Still, not all generations are interchangeable—always check the product page for SKU-level notes and brand-specific fit guidance before purchase.

Drop-Free vs Stick Mags

Drop-Free Mags: These full-size magazines often house the CO₂ cartridge directly. They replicate firearm weight and balance, making them excellent for reload drills and realistic training. Expect higher gas usage and added heft compared to lighter styles.

Stick Mags: Stick magazines are slim, efficient, and simple to maintain. With CO₂ stored separately, they deliver reliable feeding while keeping your kit lightweight for extended plinking sessions.

Capacity, Loading & CO₂

Bring spare 12 g cartridges for uninterrupted shooting. Cold weather lowers efficiency across all brands—keeping cartridges warm and moderating your shot pace helps sustain performance.

Maintenance is critical: apply approved airgun oil to O-rings and valve seals, and wipe mags down after sessions. Whether the magaine type, always depressurise CO₂ systems before storage.

Avoid over-tightening piercing screws, and replace seals proactively to extend service life.

Range Essentials

Stock up on range must-haves: premium steel BBs, CO₂ cartridges, and durable targets. Safety comes first—always wear eye protection.

For organised sessions, consider mag pouches or holsters, especially if you run multiple mags during training drills.

FAQ's

How do I know if a BB mag fits my pistol or rifle?

Check the product description for model compatibility and brand family notes. When uncertain, match by exact SKU and manufacturer to avoid fit issues.

My mag is leaking—what should I do?

Apply a drop of approved airgun oil to seals, ensure the CO₂ cartridge seats evenly, and avoid over-tightening. If leaks persist, inspect or replace O-rings/valves.

Are BB mags affected by cold weather?

Yes. All CO₂ magazines lose pressure in low temperatures. Keep cartridges warm and pace your firing for more consistent results.

Do BB mags work with airsoft or pellet guns?

No. These magazines are designed exclusively for .177 cal / 4.5 mm steel BB platforms. Airsoft (6 mm) and pellet systems use different magazines and clips.
