GHK High Output G.2 Gas Powered Magazine — GHK M4 Series (42rd, Metal Shell)

Upgrade your GHK GBB rig with the GHK High Output G.2 Gas Magazine, a purpose-built second-generation magazine engineered for peak reliability, authentic weight, and sustained field performance. Designed for GHK’s family of M4 GBB platforms — including the G5 and PDW variants — the G.2 mag refines an already excellent design into a durable, high-output workhorse that complements tuned gas blowback rifles.

Built like the real thing
The G.2 features a durable metal shell finished with a manganese-nitrate phosphate treatment that resists corrosion and wear while maintaining a low-gloss, tactical appearance. That heavy-duty exterior isn’t just for looks — the heavyweight construction gives your rifle a realistic balance and magazine feel, improving handling and reload ergonomics so your setup feels more like the real firearm.

Optimized feeding and reliable performance
Inside, the magazine uses a high-tension spring engineered to feed consistently through long strings of fire. The 42-round capacity strikes the ideal compromise between realism and sustained engagement — plenty of rounds for CQB and field sorties without the complications of high-cap gears. The G.2’s internals and gas routing are tuned for smooth, dependable cycling with GHK M4 systems, reducing misfeeds and helping your gun run exactly when you need it to.

Engineered for GHK platforms
This magazine is purpose-designed for GHK G5, PDW, and other M4 series gas blowback rifles. As the “2nd Version” of GHK’s GBB M4 magazine, it incorporates refinements learned from the original design to improve seal longevity, gas efficiency, and durability under heavy use. If you run modern GHK M4 GBBRs, this magazine is a direct, drop-in upgrade that keeps your platform reliable during short skirmishes and extended ops.

Realistic weight, better balance
One overlooked advantage of metal magazines is how they change the weapon’s balance. The G.2’s heavier profile shifts the center of gravity closer to the receiver, making your rifle more stable when shouldered and more comfortable during long sessions. That added heft produces a realistic tactile experience when manipulating magazines during reloads — a small detail that matters to serious mil-sim and training players.

Field maintenance and care
The manganese-nitrate phosphate surface treatment protects the mag against surface corrosion, but routine maintenance extends life and performance: keep the mag’s sealing surfaces clean, periodically lubricate O-rings with silicone oil, and inspect the feed lip and spring for wear. When not in use, store magazines dry and at moderate temperatures to preserve seals and spring tension.

Safety & warranty note
Modification of Green Gas and CO₂ magazines to accept aftermarket HPA fittings and valves will void all included warranties. Converting gas magazines for High-Pressure Air (HPA) use can expose components to pressures they weren’t designed for and may cause damage or failure. Use the magazine as intended with compatible gas types and follow manufacturer guidance.
