Elevate your sidearm performance with the hard-hitting mechanical action and custom competition aesthetics of the WE Hi-Capa 5.1 K2 Full Metal GBBP! Engineered by WE-Tech for players who demand extreme durability, rapid slide cycle times, and impressive firepower, this full-metal 2011-pattern gas blowback pistol is built to excel in intense CQB firefights and outdoor skirmishes alike.

Full-Metal Vented Slide & Aggressive Tactical Ergonomics The centerpiece of the K2 variant is its full-metal aluminum alloy slide, featuring custom weight-reducing port cuts along the front and sides. These precision cuts reduce moving mass during cycling, resulting in ultra-fast slide response, reduced muzzle climb, and better gas economy. Aggressive front and rear slide serrations provide exceptional tactile traction for cocking or press checks. The lower polymer frame is contoured with deep stippled checkering for a secure grip, while an integrated 20mm lower Picatinny rail allows effortless mounting of weapon lights or aiming lasers.

Snappy Gas Blowback Action & Double-Stack Firepower Powered by Green Gas or Top Gas, the WE K2 utilizes a heavy-duty blowback nozzle assembly that delivers a crisp, tactile recoil impulse per shot. The double-stack metal magazine holds up to 30 BBs, giving operators a distinct capacity advantage over standard single-stack 1911 sidearms. An enlarged flared magazine well attached to the base of the grip acts as an instinctive funnel, allowing for seamless, high-speed magazine swaps under heavy match or skirmish pressure.

Target Acquisition & Adjustable Precision To assist with rapid sight alignment in dynamic shooting conditions, the slide features high-contrast combat sights that draw ambient light for a bright, intuitive sight picture. The skeletonized match trigger offers a crisp, lightweight single-action break with a short reset for rapid follow-up shots. Internally, a precision brass inner barrel is paired with a fully adjustable hop-up assembly, enabling operators to fine-tune BB backspin to achieve flat, pinpoint trajectories across varied engagement distances.

Whether you are completing a custom action-shooting loadout or seeking a battle-proven, full-metal sidearm with high magazine capacity, the WE Hi-Capa 5.1 K2 Full Metal Gas Blowback Pistol delivers the power, velocity, and aggressive styling needed to take command of the field.

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.
