The Hakkotsu Thunder B sound grenade is a highly realistic sound distraction device which is modeled after the stun grenades (aka. flashbang) used by military and law enforcement entry teams when breaching a building or clearing a room. The size, shape and function of the Thunder B is very similar to the real grenade which makes them extremely fun to use and heightens the excitement of airsoft engagements.

The Thunder B sound grenade is powered by a single 12 gram CO2 cartridge. When you pull the pin and release the spoon, compressed CO2 is released into the outer plastic shell. When the shell reaches its maximum pressure after approximately 5 seconds, it detonates in a thunderous boom similar to an MRE bomb. The shouting and series of hand signals which ensued after the initial inner office detonation concluded that the Thunder B was a lot louder than we had anticipated. The sound which this thing produces is no joke. It registers around 130db and it will definitely make you flinch. The shell typically ruptures down the sides and usually stays in once piece so there is minimal risk of flying debris.

We have also experimented with putting about 500 BBs into the shell which resulted in BBs being hurtled about 50 feet in several directions. You can also mix about 2 tablespoons of baby powder in with the BBs, or just have baby power alone, which results in a nice simulated smoke cloud upon detonation. (Do note that the more area which is filled inside the grenade, the less time it takes to go of. So, experiment at your own risk.)

To arm the Thunder B grenade, cock the striker back and insert the safety pin into the rear hole of the striker housing to hold the striker back. Close the spoon (handle) over the striker and hold it firmly. Remove the pin and reinsert it into the front hole to secure the spoon with the striker underneath of it. Then, a single 12 gram CO2 cartridge is inserted into the primer core. The primer core is then inserted into the disposable plastic shell and screwed on just like you would screw on a bottle cap. Your Thunder B grenade is now ready to rock and roll.

The Thunder B sound grade is reusable although you will use up 1 CO2 cartridge and 1 sound grenade shell for each detonation. Replacement shells are available from us and only cost about $1.25 each.

Comes with: Primer core assmebly, 4 safety pins and 12 shells.

WARNING: While this device is robustly made it can still be damaged if it impacts a rock, a tree or other hard objects when traveling at high velocities. For this reason we do not suggest chucking the Thunder B like the opening pitch at the World Series but rather more like an underhand horizontal toss. Tossing in this manner will be greatly appreciated by the Thunder B as well as any player on the receiving end.

5 out of 5- Worth it.

So I just got mine today and was very excited to test it. When I opened the box I was very surprised at how light the package was, only about one pound. The entire grenade was in about 4 different pieces, and had no instructions on how to assemble the grenade. Shorty does an OK job of explaining it, but pictures would be nice.

Once the grenade was armed I went to my garage to set it off, but no "pop" ever happened. You will have to screw the shell onto the core EXTREMELY tight for a good toss. On the second toss, the results were more than what I had expected. The pop was so loud that I had ringing in one ear for a few seconds after. The shell had split open nice and wide just as Shorty said it would. The third test was with about 40 BBs (20 .12g and 20 .2g) in the shell and the results were once again better than I had hoped.

This grenade has solved almost every problem set from past airsoft grenades. With the way it works (A pin hitting the CO2), it seems almost impossible to wear out.

Pros......
EXTREMELY Effective
Low unit cost
Can fill many grenade type roles
Fun to use.

Cons......
Not reusable
Hard to "work" the first toss
No instructions.

My only suggestion would be to buy a pack of extra shells, and Shorty needs to carry extra primer cores, to carry more than one grenade.

Overall 10/10

5 out of 5- Must Have for a Serious Player

Multiple Applications:
Stun Grenade
Booby Trap/Early Warning device for doorways or avenues of approach (use clear fishing line)
Fill with some BBs and use as a frag grenade (* See below)
I like the Baby powder idea Shorty had above, that’s very effective!

Miscellaneous Info:
Delay gives you approx. 3 seconds
No flames involved so it's safe to throw in dry brush
Unless you fill it with BBs there isn't any shrapnel so you can throw it close to people
The casing is a onetime use and it takes a new CO2 every time so approx. $2.00 per shot (find a cheap CO2 supplier and stock-up!)
Save your money and don't buy replacement pins unless you lose the ones it comes with
Sounds like a high caliber gun shot

*Game Option – Instead of throwing this grenade full of BBs my friends and I have opted to go with the Baby power and consider anyone within 15” of the explosion as hit. This way you aren't throwing frags at people.

In my opinion it's worth the money if you’re an assault player, maybe not as useful if you're a sniper.

Rate if you would please.

5 out of 5- Word of caution.

I have seen this in action and will give a word of caution.

This goes off at the sound level of a GUNSHOT! needless to say hearing protection is recommended, otherwise I would NOT throw this near somebody since they might get permanent hearing damage, look up Tinnitus, it's not fun, I have permanent hearing damage from serving in the military.

Also, a law enforcement officer may be called if someone reports a loud bang in your neighborhood, and they may perceive your grenade as a real explosive.

5 out of 5- LOL

This is loud and funny as hell. When you pull the pin it is the coolest feeling. The only problem is their one time use. But they're cheap to replace. It's very cool. If i were you i would get it. And by the way when i brought it to my friends house during the battle they thought is was a little tiny thing but when it went off they almost sh** their pants. And you can also put bbs in there. They will fly all over.

5 out of 5- must have

These sound flashes are absolutely awesome. When they arrived at my house I wasn't sure what to expect. After detonating the first one I was amazed. I had every dog in my neighborhood barking from the enormous bang it produced. Perfect for catching your enemy off guard and it will leave him wide open for attack. It has a perfect assembly and is easy to use. Even though it takes one co2 per each detonation it is well worth it. A very fun item. Warning: do not detonate inside as I accidentally did and my ears were ringing for almost an hour. But this item is a blast. So much fun. In my opinion it's a must have

5 out of 5- Awesome

This grenade is sweet. It's loud as hell and sprays BB's all over the place. The only complaint I had with this was that half of the shells it came with had slashes in the grooves so they wouldn't go on straight and leaked out my Co2. You just have to make sure the shell is on very tight and straight. I love this grenade and definitely recommend it.
