This is a high-capacity (500 BBs) Hi-Cap magazine for AK-type airsoft guns from the popular manufacturer Cyma. These magazines are widely used in the airsoft community due to their simplicity, large ammunition capacity, and versatility for long games.
Design and principle of operation
- Type: Hi-Cap (High Capacity) – a hopper magazine with a large capacity for BBs (500 pieces).
- Filling: BBs are poured directly into the upper opening of the hopper (just open the lid); the mechanism is wound manually using the appropriate key.
- Ball feed: an internal spring-loaded feed mechanism pushes the ball to the hop-up outlet, ensuring continuous firing after winding.
Advantages of Hi-Cap:
1. Large capacity – minimizes the frequency of reloading during play.
2. Easy loading without additional devices (loaders).
3. Convenient ball supply – especially for fast or long CQB/Outdoor scenarios.
Disadvantages to be aware of:
- May be heavier and louder than Mid-Cap or Low-Cap magazines when moving.
- The mechanism must be periodically adjusted to maintain ball feed.
Compatibility and tuning
- The magazine is designed for AK series drives (AK47/AKM/AK74-like AEGs), including models from Cyma and many other manufacturers.
- Due to differences in drive design, there may be cases where the magazine does not fit perfectly—in such situations, slight adjustments may be required (e.g., adding thin shims or lightly filing down protrusions).
- The Hi-Cap profile does not always work with replicas that closely mimic the standard geometry of real weapons, but it works correctly with the most popular AEGs.
Care and maintenance
To extend the life of the magazine and avoid problems with ball feeding, we recommend:
1. Always remove the BBs from the feed channel after use to relieve pressure on the spring and thus reduce the load on the mechanism.
2. Lightly lubricate the feed mechanism and channels with silicone grease - this improves BB feeding and minimizes friction.
3. If you are inexperienced, entrust maintenance to specialists to avoid damaging internal components.
Operating tips
- For long gaming sessions, it is advisable to have several magazines, as constant reloading can be inconvenient in dynamic scenarios; Mid-Cap is an alternative for those who want to avoid reloading.
- Avoid overfilling beyond the stated capacity, as this can lead to jams or spring overload.
