I’m a huge fan of BB Airsoft Grenades and over the years have collected most of them. While at IWA I saw the Storm 360 in the ASG booth and I was immediately interested. While it looked bulky it comfortable in my hand, and importantly it felt durable. 6 months later, I finally got myself a Storm 360 and this is my review.
BB grenades might not have the guaranteed room clearance like Blank-Firing grenades, but it’s way more rewarding hearing 100+ BBs fly around claiming HITs when you toss one in.
For countries that don’t allow blanks, or players who are under 18 it’s a great alternative, and personally a lot more satisfying.
As it’s name suggests, the ASG Storm 360 Impact Grenade; hits the ground, exploding into a spinning frenzy while launching 165 BBs in a full 360 degrees.
Let’s look at what’s in the box.
Every Storm 360 Airsoft Grenade comes in a cardboard box, along with instructions, metal spoon and of course the grenade.
I have the NEON GREEN model, but it’s also available in Olive Drab Green, Black, Urban Grey and Danger Red.
With a ~£50 price tag, I’d advise buying a bright colour to avoid losing this after thrown.
Top Tip: Also, stick your initials underneath to help any marshals find you, should they come across it on site.
Internally, these have extremely basic and reliable mechanisms. On the outside is a 2 piece shell, that contains a single spiralled channel for the BBs running down to the bottom.
At the bottom is a vent leading to the inside core of the grenade. This is where the gas escapes, launching BBs up and out the spiral.
Inside the core is a gas chamber, a large ball bearing and a rubber grommet. When you fill the grenade up with gas, it closes the ball bearing on the grommet and creates a seal. Upon Impact, the ball bearing is knocked out of position leaving a hole for the gas to escape.
Even though you know how it this airsoft grenade works, it is sold as a sealed unit, so there is nothing you can do if anything went wrong.
But with such a simple design – there isn’t a lot of failure points.
To use the grenade, simply pull the spoon out. This will release the Armed-Button and it will extrude from the top (this is perfectly normal)
Now you can throw the grenade, under-arm onto a hard surface, be aware it will detonate immediately upon impact.
To rearm the grenade follow the same process from the start, push down the armed button, insert the spoon, re-gas, insert BBs and go again.
It’s one of the fastest reloading BB Grenades available.
As a sealed unit, there isn’t a lot of maintenance required. Put a small amount of silicon oil down the armed button, this can then soak into the grommets internally.
Having thrown the grenade more than 20 times across different site environments I’m confident in saying there is a good 10m spread on a full 360 degree spin.
My best results were when the grenade went off on it’s side, as this allowed the grenade to spin around the most. Take a look…
Sometimes a second knock or bounce was required to eject more BBs, I’m presuming the ball-bearing fell back onto the o-ring and stopping gas ejection. This meant that on occasion the grenade would still contain some BBs after use.
For a more effective spin, loading up around 100-120 BBs per use gave more gas efficiency, using all the BBs and still covering the same amount of spread.
In regards to drop-tests, the grenade goes off fairly easy at a small distance (50-60cm). I’ve had it set off from the thigh provided it’s landing on a hard enough surface.
Talking surfaces, soft surfaces can cause lacking results, this is due to the gas not being able to propel the grenade around with enough force.
Remember, the spin and bounce is required to get the full potential and coverage from the Storm 360 Grenade.
Here are my positive points from the ASG Storm 360 Review:
Every product has a negative, some universal, others by design. Here are my cons on the ASG Storm 360:
Overall, this is still one of my preferred CQB grenades due to how reliable and easy it is. While these types of grenades will always have varying results, I’m confident it’s going to go off every time.
Yes the external build quality is great, but if I was using it every weekend I’d be a little concerned of it’s long term lifespan – that said, I cannot deny it’s current effectiveness and durability (just scrapes and scratches).
Due to the size I keep it in my dump pouch, which in CQB is fine, however for woodland games I run into issues as I’m wearing just a chest rig. On my Viper Spec-Ops Chest Rig it doesn’t fit into any pouches, so I’m using my trouser pockets, it’s less than ideal but it works for now.
Finally, I am worried about what happens if the grommet internally splits, but at this point I would have to contact my retailer or ASG – and so far (fingers crossed), it’s not been an issue – let’s just hope it stays that way.
Elements, a 3D Printing company in France do make Holsters for the Storm 360 as shown above. You can find them at ElementsFrance.FR
