KWA K400 High Cap AEG Magazine, 3-Pack
KWA K400 400rd High Capacity M4/M16 AEG Magazine (3-Pack)
Keep your ammunition stores fully packed for when encounters turn chaotic, and secure a significant combat advantage with the KWA K400 High Capacity M4/M16 Magazine 3-Pack. Engineered to fulfill the high-volume ammunition requirements of modern airsoft operators, each individual magazine in this bundle accommodates an impressive 400 rounds of 6mm BBs. Providing a staggering combined total of 1,200 rounds straight out of the package, this continuous-feed configuration ensures your squad has more than enough firepower to suppress and eliminate opposing fireteams during extended engagements.
Overview
The KWA K400 High-Cap is precision-molded from a specialized nylon-fiber-reinforced polymer compound. This high-grade industrial material creates a featherweight yet incredibly rigid outer shell architecture, granting players the tactical freedom to carry multiple backup magazines comfortably across their vests without feeling weighed down by traditional stamped steel housings. The exterior shell design integrates pronounced, ergonomic finger grooves that maximize friction, ensuring secure retention and fluid reloads even in slick, muddy, or rainy environments.
Internal components are heavily reinforced to withstand continuous tactical operations. A robust internal main tracking spring applies steady, uniform pressure to the feeding mechanism to feed ammunition seamlessly into your AEG's firing chamber, virtually eliminating skipped feeds or mid-match mechanical jams. Tailored specifically to lock natively with the industry-leading geometry of KWA M4 and M16 series airsoft electric rifles, this high-capacity magazine bundle serves as the ultimate insurance policy for intense field engagements.

Field Tips
- Winding Procedure: To ensure uninterrupted feeding, slide open the top trapdoor hatch, fill the internal reservoir with high-quality BBs, and wind the textured gear wheel at the base until the mechanical click changes tone, signaling the feeding track is under full spring tension.
- BB Ammunition Grade: Always pair these high-output KWA channels with premium, seamless, precision-polished 6mm BBs. Low-grade, brittle, or recycled floor ammunition will fracture internally and damage the gear clockwork.
- Debris Prevention: Keep the internal hopper free from sand and dirt. If foreign particles infiltrate the reservoir, blow out the tracking tracks with compressed air rather than sticky petroleum oils to avoid dirtying your hop-up bucking.
- Storage Tension Management: After concluding field matches, always empty remaining BBs out of the tracking column by holding the top release catch back. Storing high-caps under tension can cause spring memory fatigue.

Frequently Asked Questions
Do I need an airsoft speedloader to fill these K400 magazines?
No. Because these are high-capacity magazines, you simply slide back the large trapdoor hatch located on the top of the magazine and pour your 6mm BBs directly into the reservoir from your ammunition bottle or bag.
Will these magazines fit other M4 airsoft brands like CYMA, G&G, or Krytac?
While optimized natively for the exact receiver tolerances of KWA M4/M16 series AEGs, these magazines use a standard AR-15 airsoft format and will fit and feed reliably inside most major Tokyo Marui-spec M4 platform airsoft electric rifles.
Do these magazines make a rattling sound when I run on the field?
Yes. All high-capacity airsoft magazines with an open internal storage reservoir will experience BB movement and rattling sounds when partially or fully loaded. If absolute silence is required for your playstyle, consider KWA mid-capacity magazines.
Can these magazines be used with Gas Blowback (GBBR) M4 rifles?
No. These magazines are built strictly for Airsoft Electric Guns (AEGs). They do not contain gas valves, liquid gas reservoirs, or feed lips required to function inside gas blowback setups.
