King Arms 100rnd Mid-Cap Magazine for P90 & SI-90 AEGs

Description

King Arms 100rnd Mid-Cap Magazine for P90 & SI-90 AEGs

Keep your P90 or SI-90 running smoothly with the King Arms 100rnd Mid-Cap Magazine, a compact and practical spare magazine designed for P90-style AEG platforms. Holding approximately 100 rounds of 6mm BBs, this mid-cap gives you a useful balance between ammunition capacity, magazine weight and the quieter operation players expect from a mid-cap system.

Unlike a high-capacity magazine, there is no winding wheel to worry about. The spring-fed internal design provides a simple, straightforward feeding system and eliminates the familiar rattle associated with loose BBs in a high-cap. Load it using a suitable airsoft speed loader, insert it into your P90 or compatible SI-90 AEG and you’re ready for game day.

The “Pro” Take

The big advantage of a good P90 mid-cap is simplicity. There is no winding mechanism to manage and no loose ammunition rattling around inside the magazine as you move between positions. For players who prefer a cleaner, more controlled setup, the King Arms 100rnd Mid-Cap is a great match for the compact nature of the P90 and SI-90 platform.

At around 100 rounds per magazine, you’ve also got a useful middle ground between the lower capacity of some P90 magazines and the much larger capacity of a high-cap. Carry several of these in your loadout and you have a straightforward reload system that keeps the compact profile of your P90 build intact.

It’s also a particularly sensible spare magazine for the EMG Strike Industries SI-90 AEG, which uses the King Arms P90-style magazine format. If you’re running an SI-90, keeping a few additional 100-round magazines ready to go gives you an easy way to build a practical skirmish loadout.

UK Spec & Site Performance

As a magazine rather than a powered component, this accessory has no impact on the muzzle energy of your AEG. Its main job is to provide consistent BB feeding while keeping your P90 or SI-90 setup compact and easy to manage.

Always check your individual airsoft site’s magazine and ammunition rules before attending a game. For best results, use quality, appropriately sized 6mm BBs and load the magazine with a suitable speed loader rather than forcing BBs into the feed system.
