Essential Firepower for the Frontline

If you are running the magnificent King Arms M1 Paratrooper or the fully automatic M2 Carbine on the field, carrying spare magazines is not an option—it is a necessity. The King Arms KA-MAG-90 is the official factory-standard 35-round gas magazine designed specifically for this iconic lineage of gas blowback rifles. Offering flawless compatibility and highly reliable performance, these spares are vital for ensuring you don't get caught out reloading during long woodland game days or intense CQB pushes.

Heavyweight Zinc Alloy Construction

When it comes to gas blowback realism, weight matters. Tipping the scales at an impressive 573 grams, this magazine provides a highly authentic heft that drastically enhances the handling and balance of your lightweight wooden carbine. Machined from a robust, high-density zinc alloy, it is built to survive the inevitable drops, knocks, and bumps associated with fast-paced airsoft skirmishing. The sleek black finish perfectly complements the dark metal receivers of your rifle, while the durable polymer feed lips guarantee smooth, damage-free BB loading and feeding.

Skirmish-Ready Gas Efficiency

Powered by standard green gas or top gas, the KA-MAG-90 features an expansive internal reservoir that provides excellent thermal mass. This helps to mitigate the dreaded "cool-down" effect during rapid fire, which is a particularly crucial feature if you are unleashing suppressive full-auto bursts from your M2 Carbine. The precision-engineered release valves deliver a consistent, punchy gas flow to the bolt, ensuring you get a crisp recoil impulse and stable FPS from the first shot down to the very last of its 35-round capacity.

Key Features at a Glance

  • 35-Round Capacity: Strikes the perfect balance between sustained firepower and classic GBB realism.

  • Premium Materials: Heavy-duty zinc alloy body offering an incredibly realistic 573g weight.

  • Smooth Feeding: Robust polymer feed lips protect your BBs and ensure jam-free cycling.

  • Power Source: Optimised for standard Green Gas and Top Gas for excellent UK weather performance.

  • Direct Compatibility: Specifically engineered by King Arms for their M1A1 Paratrooper and M2 GBB carbine series.

The Verdict

A gas blowback rifle is only ever as good as its magazines. By stocking your webbing pouches with genuine King Arms KA-MAG-90 spares, you guarantee that your historical WWII or Korean War loadout remains a highly competitive threat on the modern airsoft battlefield.

Faulty Product?! Unfortunately that is part of life but be rest assured we are here to help! Contact one of our friendly staff via phone or email. Stating what the problem is, if we can resolve the problem via phone or email great if not then they will advise how to send it back and what details we require.

Two tone
We can two tone any weapon we sell at Bespoke Airsoft. The purpose for two toning is if you do not hold a valid defense under the Violent Crimes Reduction Act (VCRA, 2006) which is to prevent the misuse of Replica Weapons, which applies in England, Scotland, Wales and Northern Ireland.

The gun will be sprayed 51% in a bright/primary color (we do only blue, green and red currently). The process of two toning currently runs at 2 working days depending on Drying Time, which is effected by Ambient Temperature and Weather. and currently no express delivery is available for this even if you select it at checkout.

FAQs

1.     What is a BB gun used for?  BB guns are mostly used for practice shooting and training. The stronger ones (i.e. Air Rifles) can also control pests or hunt small animals.

2.     Do you need a Licence in the UK for a BB gun? No, you don't need a licence for a BB gun in the UK, but there are rules. The BB Gun needs to be in two colours; one has to be a primary. All our guns are on the website as per default.

3.     Is a BB gun a good weapon?   BB guns, despite sometimes being seen as toys, can be dangerous. They fire pellets at high speeds and can cause serious harm, or even be deadly in some situations.

4.     Can you shoot BB guns in public in the UK without a Firearm license? BB guns in the UK navigate a legal grey area. While certain models, notably low-power 'soft air' types, typically evade classification as section 1 firearms, more potent versions may require a valid firearms certificate to avoid legal repercussions.

5.     Can you shoot a BB gun in your garden? You can use a BB gun in your garden under UK law, but you have to ensure the pellets don't go into your neighbour's yard, plot or land. If they do and you don't have permission, it's against the law.

6.     Which UK law am I breaking if the pellets go into my neighbour's law without permission?  If your BB gun pellets go into your neighbour's yard without permission, you're breaking UK laws. Specifically, the 1968 Firearms Act and possibly the 2003 Anti-Social Behaviour Act, because you may be causing your neighbours trouble or worry.
