Double Bell 24-Round Green Gas Magazine for TM M9 Series GBB Pistols — Reliable, Compact, and Battle-Ready

Give your M9-style gas blowback pistol a dependable spare that’s built to last. The Double Bell 24-Round Green Gas Magazine is a factory-grade replacement mag crafted to the tolerances TM-style pistols expect. With a durable metal-alloy body, a high-strength feed spring, and a compact 24-round capacity, this magazine is perfect for skirmishes, training, or keeping a faithful backup on your kit.

Solid construction — built for real use

The magazine’s metal alloy construction provides a rugged exterior that resists dings and deformation while delivering a realistic heft in the hand. Compared with cheaper polymer replacements, a metal alloy magazine stands up better to drops, repeated loading cycles, and the abuse of field use — which means fewer fitment issues and longer service life.

Reliable feeding every shot

At the heart of this mag is a high-strength internal spring engineered to put consistent pressure on the follower, resulting in smooth, repeatable feeding from the first BB to the last. For gas blowback pistols, reliable feed geometry is crucial — and Double Bell’s factory replacement design mirrors the original magazine dimensions and feed lips to keep your M9 cycling cleanly.

Compact capacity for realistic play

With 24 rounds per magazine, this mag strikes a balance between realism and practicality. It’s ideal for players who prefer realistic reloads and mid-cap style engagements without constantly winding or dealing with rattling hi-cap internals. The smaller capacity also encourages tactical reloads and ammo discipline, which many mil-sim players and instructors appreciate.

Drop-in replacement — perfect fit for Double Bell 736 series

This magazine is a factory replacement for the magazine shipped with the Double Bell 736 series, designed to work flawlessly out of the box. If you run a compatible TM-pattern M9 GBB, installation is simple: load it, seat it, and you’re ready to go. The magazine was built to match Tokyo Marui-style dimensions for broad compatibility among TM-pattern M9 pistols.

Maintenance & best practices

To keep your magazine feeding flawlessly:

• Break it in: Load and unload the mag several times before first use — this helps the internal spring settle and improves long-term reliability.

• Lubricate periodically: A small spray of silicone oil on the follower and spring after extended use keeps everything moving smoothly.

• Temperature tips: Green gas performance can vary with temperature; allow magazines to return to ambient temperature between rapid reloads for the most consistent FPS.

• Storage: For long-term storage, unload the magazine and keep it dry to preserve spring life.

Important safety note

Do not modify this green gas magazine to accept aftermarket HPA fittings or CO₂ conversions. Modifying gas magazines for HPA or high-pressure systems can damage the magazine and void all warranties due to the risks introduced by higher pressures and misuse.
