    This guns is just wow.
    Even the metal looks like it come from the 1940’S. It’s heavy and tough; it really can take a beating. It shoots true and the hop up is in the perfect place, you can adjust it on the spot. With the king arms drum mag on it it’s a beast on the field. Opponents tend to stay clear of your position. Good for any WW2 fans or just someone who wants a kick ass gun.

Buying airsoft guns in Canada has never been so simple. As long as you are over the age of 18, they are legal to purchase and own. However, you can not discharge your airsoft guns outside of a designated playing field or private property. You are also not permitted to display/discharge the airsoft guns in public. Always treat your airsoft guns as actual firearms: with the utmost responsibility. Failure to do so can lead to legal punishment. If you have other questions, please consult your local law enforcement.


Electric guns, or more commonly known as AEGs, are the most popular form of airsoft gun. Their popularity is due to their consistency, ability to upgrade, and availability. The are powered using rechargeable batteries. The most common being NiMH or LiPO. Stock AEG rifles in Canada typically shoot 366 FPS+ using a 0.20g BB. The majority of AEGs have a fire selector, allowing you to choose between Safe, Semi-Automatic, and Full-Automatic. The AEG is the most recommended platform for all of these reasons.


Spring powered guns are simply powered through a cock and shoot system. To operate, you either pull back the bolt handle or pistol slide to cock, return to forward position, then pull the trigger to shoot. Using an internal piston and compressed air to function, spring guns are the most cost-effective option. We carry many high-powered sniper rifles, along with internal and external upgrade options available to truly maximise their potential. While these types of guns have an extremely low rate of fire, you do not have to worry about running out of gas or your battery running out of power.


Gas powered guns are revered due to their realism. They use compressed gas to propel the BB through the barrel of an airsoft gun. Most will have a realistic blowback feature, which will either internally cycle a bolt or externally cycle a slide. The types of gas used in these airsoft guns are either Co2 or Green Gas (propane). These types of guns typically have magazines that have realistic capacities, which makes these guns ideal for MILSIMs and target shooting.


Airsoft grenades are used for taking out small or large groups of people using the element of surprise in a single shot. Whether the are a timer grenade, impact grenade, or a shower shell, there are many forms that can the job done right. We also carry sounds grenades, which alarms the enemy, allowing you to storm when they are confused. You’ll know it when you hear one go off!


What is the difference between CO2 and Green Gas? Here is a quick comparison: CO2 is a high pressure gas, meaning you will get a higher velocity and a snappier blowback. They perform better in colder temperatures and typically last longer in a pistol magazine than Green Gas does. Green Gas is a mixture of propane and silicone oil. This prevents your guns seals from being dried out. It doesn’t perform as well as CO2 in colder temperatures, but it is typically cheaper than CO2 and it causes less strain on your guns. There is no clear cut winner between the two, so if you have questions, please email our staff at!
