Q: How far do these shoot?

A: Range will depend on the type of shell used, not the launcher. Remember it's the shell doing the shooting. The shell is not the projectile but the host for the projectiles. For range expect the BB shower type to go 50 feet or less in a large shotgun blast type cloud. It's not accurate but scares a lot of people! For the ones that can launch rockets, with the right foam rocket or projectile you can see these things go 150 feet or more (arcing shots of course).

Q: Are the shells reusable?

A: Yes, you just reset the valve, fill with gas, and load up the shell again. The release valve is the part that gets activated by being pushed by your launcher. It sometimes locks into the "fired" position and will have to be reset before you fill it with gas again. You can reset it by pressing it with your finger or something blunt until you hear a click, and then have the valve return to the centered position. It takes a little practice but is easy to do.

Q: How do you reload the ASG 40mm gas grenade shell?

A: Reloading the grenade is straightforward. First, pour all 90 BBs into the center chamber. Next, seal the chamber with the provided rubber stopper. Finally, charge the grenade with gas, and it is ready for use. It's designed for easy and quick reloading, making it efficient for use in multiple grenade launchers.

Q: What makes the ASG 40mm grenade ideal for airsoft?

A: The ASG 40mm grenade is designed for airsoft use, replicating the effect of a real grenade with a gas propellant to shoot 90x or 65x 6mm BBs depending on the size you get. When fired from a grenade launcher, it releases all BBs simultaneously, creating a significant blast ideal for room clearing and suppressive fire. Its ability to fit in all launchers and its powerful discharge make it a versatile and effective tool in airsoft games.

Q: What should be considered when choosing an airsoft grenade like the ASG 40mm?

A: When selecting an airsoft grenade, consider the number of BBs it can fire, as more BBs increase the chance of hitting the target. However, a higher BB count usually means less power per shot and shorter range. Additionally, heavier BBs offer more stable flight and greater impact energy. The choice of grenade launcher also matters; a short barrel launcher is suitable for close-range with wider BB spread, while a long barrel is better for medium range with tighter BB spread.

Q: Is there any restriction on the type of propellant used with the ASG 40mm grenade?

A: The ASG 40mm grenade is specifically recommended for use with green gas only. This is an important consideration for users to ensure safety and optimal performance. Using other types of propellants might not only reduce the grenade's effectiveness but could also pose safety risks.

About the ASG 40mm Gas Grenade

The ASG 40mm gas grenade shell represents a significant advancement in airsoft technology, combining precision engineering with practical design. Crafted meticulously with CNC machined aluminum, this grenade shell is not only robust but also boasts an enhanced air seal, thanks to its high-quality silicone o-rings. This combination of durability and efficiency makes it a reliable choice for airsoft enthusiasts.

A standout feature of this grenade is its capacity to hold up to 90x 6mm BBs, setting it apart in terms of firepower. The inclusion of 10 reusable plugs underscores its user-friendly nature, facilitating easy resetting for multiple uses. This feature is particularly beneficial for players who engage in frequent airsoft matches, as it allows for quick reloading and continuous gameplay.

Reloading the ASG 40mm gas grenade shell is a swift and effortless process. Users need only to fill the central chamber with 90 or 65  BBs, seal it with the provided rubber stopper, and then charge it with gas. This simplicity in reloading, coupled with its compatibility with various grenade launchers, makes it a versatile and indispensable tool alongside your main airsoft gun. The grenade's design enables it to be used in all types of launchers, enhancing its appeal to a wide range of players.

When choosing an airsoft grenade like the ASG 40mm, several factors need to be taken into account. The number of BBs a grenade can discharge plays a crucial role in its effectiveness, as a higher count increases the likelihood of hitting the target. However, this comes with a trade-off in terms of shot power and range. Moreover, the weight of the BBs influences their flight stability and impact energy, with heavier BBs offering better performance in these aspects. The choice of grenade launcher also impacts the grenade's effectiveness; short barrel launchers are ideal for close-range encounters, providing a broader spread of BBs, while long barrel launchers are more suited for medium-range engagements, offering a tighter BB spread.

The ASG 40mm gas grenade shell is a notable addition to the airsoft arsenal, offering a blend of durability, efficiency, and versatility. Its ease of use, coupled with its compatibility with multiple grenade launchers, makes it a popular choice among airsoft players. Whether used for room clearing or suppressive fire, this grenade adds a dynamic and realistic element to airsoft skirmishes, enhancing the overall gaming experience.

The ASG 40mm Gas Grenade is a 40mm grenade designed to be used as either a shower shell or to propel projectiles out of a 40mm grenade launcher.

The most common type of 40mm airsoft shell is the BB shower shell. These are gas powered shells that feature multiple "barrels" which you load to the top with BBs. These can hold as few as 50 shells to several hundred. When fired, a stream of BBs shoot out much like a shotgun blast. Other types feature a big bore which can be used to launch paintballs or foam rockets (and Nerf balls/rockets). These are great fun though you'll have to check with your local field or event holder if these are field legal. The gas grenades when fired emit a loud pop which can be startling to some so use caution.

These shells are powered by green gas and usually take a 3-5 second charge time to fill, maybe longer. As with any gas powered airsoft item, these shells will require care and maintenance to keep them in good shape and not leaky over time. The simplest thing you can do is put silicone oil on the valve and then charge the valve with gas to fill it. The gas will push the silicone into the shell and the pressure will distribute the oil to everywhere inside including the o-rings, which is the component you are trying to oil. Any small leaks can be addressed with the silicone oil and any big leaks can be detected this way. These shells have small ball bearings and complex parts. DO NOT disassemble unless you are qualified. Parts will get lost and you will void your warranty.
