Mad Bull GSG-1 CO2-powered "Stun" grenade out now.
 

Hey all.

For those that may have missed it - the Mad Bull Airsoft GSG-1 "stun" grenade is out now.

Apparently this thing releases a sound burst over 120dB strong. Owies, that's loud.

On a side-note, any field owners out there with an opinion as to whether or not something this loud would be permitted?

Interesting, but 120dB is pretty much the limit where permanent damage can start occurring. I'd worry about it in enclosed spaces, or if exposed to a lot of them. It's the level you'd definitely want to be wearing hearing protection.


Actually here's a neat chart:

http://en.wikipedia.org/wiki/Sound_pressure


Not listed in there, but thunder is about 130dB (when you're right under the storm).

HA!

I was going to post one of those charts to give an idea as to just how loud this thing is.

So, field owners - let's hear from you. Now that you have an idea as to what this thing is like. Can it be used on your fields?

personally I dont think Id allow them on my fields, outdoors MAYBE, but indoor CQB, no. Indoors where the sound is contained and having these things go off over and over would be a bad thing for everyone's hearing.

A 120db is about the sound of a pneumatic chipper or riveter that you are using! A .22 shot is about 140db if I remember correctly....

Lovely, a stun grenade that could actually really work on someone.
Thumbs up on the idea (Im so gona buy like 10) Thumbs down on the possibility of hurtin someones ears.
But just out of curiosity, its c02 powered, could this grenade be safely run on propane with less power?

As is my understanding.

However, I've asked my contact for some clarification, and what the dB measurement results are for other pressurized gasses like propane and duster. I'll post here and on my site when I get my reply.

Like I said, on outdoor games these would just be fine BUT if you were lying in a hollow and one of these goes off next to your head, expect hearing loss for awhile....

Indoor games there would be no doubt that these would be banned!

I would not participate in any game allowing these. I would castrate the one who sneeks one in and uses it anyway.

Hearing loss and ear damage is no joke. When I was 13 I had a fire cracker go off about 25 cm or so from my right ear. The temporary damage was bad enough but something in my brain, like intuition or whatever, told me I had really done it that time. I caused permanent damage and unfortunatley due to my oversensitive hearing, I don't get away scott free with just a little numbing of the sense. I have permanent ringing in that ear....24 hours a day, 7 days a week, 365 days a year....forever. It also affects my balance and I actually have to knowingly compensate for it a lot of the time....my coridination has never been as good since.

Trust me guys, these are by far not worth the risk. The variables are massive when this thing goes off. And if they turn out not in your favour, you could be stuck with the effects for the rest of your life. A constant high-pitched scream is not pleasent and is often unbearable, believe me, I know!

How long is the duration of the sound? What kind of sound? Bang? Squeal?

I think the point of a "stun" grenade is to "stun" the opponent. The 120dB is point blank beside you. In a closed room, the sound disperses... My KJW M9 on red gas clocks at almost 107dB within 1 foot range and nobody has complained so far. Since this thing is gas powered, it probably makes a low frequency pop rather an ear damaging higher frequency snap. Besides, aren't most of you guys wearing radio headsets?

No.

And that's not applicable since most people have only one ear covered.

The only real danger with this is if someone throws one besides someone lying down right besides the ear.

I dont think this is good for games, this should be used only for simulation exercices in a controled situation.

AKA tossing into a drunken frat party :D

how much , and can it be brought into canada (i think it it would be like any other airsoft grenade and customs would have a new toy)

Customs wouldn't likely seize it (as far as I know). I've ordered a Tornado and PFI grenade and they were passed over during a customs inspection. Although, they CLEARLY look and feel like toys.

This is made of aluminum and could go either way. JAG Precision in the US is the North American distributor of Mad Bull products - so you can probably ask them.

www.AirsoftParts.ca, www.Xtreme-Tactics.com/store, and (I think - correct me if I'm wrong) www.CapitalAirsoft.com all carry a plethora of Mad Bull products in Canada. They should be your first point of contact for pricing.

Judging by the sound of it - you probably won't be able to use this in a gaming capacity however.

Depending who you have in the house for a family,these might be good to
deter home invaders.You can have your ear plugs in and toss these
puppy's at the jerks.Or you can have them on trip wires outside doors or
or windows for when the little woman is home alone.Just an idea.:D

YouTube - GSG-01 try out-06

An example of the stun grenade being used.

wow, this thing would be good for getting the attention of a classroom. but the number of legalitys would be scary.

IMO, if rock concert surpass sound level of 120db why this is not safe to be used in the game? most of us are using balaclava to protect ears so the sound wave coming from the bang should be dampened a little bit when it reach our eardrums, beside the loud sound from the bang might be spread through out the room not focused into your eardrums and lessen if you are playing outdoor... as long as it doesn't banged right in front of your ears, it should be not that dangerous, CMIIW

Can't you set that thing to lower down the power?

I'd like to get myself one.

next issue..... anyone found out the MSRP yet?

120dB isn't that bad. Keep in mind it's 100 times quieter than a .22
I work with +200dB sound all the time, now that will screw you 3 ways from Sunday.
Cheers,
Grant

Hmm... that would be interesting; might scare the crap out of someone if they're not expecting it, heh heh.

madbull claim the 120dB is just as loud as an 0.22cal .. and thats not very loud....

120db = 30 seconds of exposure can cause lasting damaging to the ear drum. Granted this thing only goes bang but how many times during the day will you be exposed to it?

120db is really not that loud.

www.capitalairsoft.ca ;)

Unfortunately, I have zero Madbull products at this time. I'm working on that issue however!

so your telling me i pull the pin on this thing and BLAM
Metallica is in the field making our ears bleed?

OK.

I got a response from Mad Bull. This product is NOT to be used with any gas other than CO2. No propane, no duster, CO2 only. They would not comment on whether or not it could technically be possible, as they likely haven't tested it - and by the sounds of it, they probably won't.

As for the earlier question as to whether or not the pressure can be tuned - no it cannot. Mad Bull also pointed out that the decibel output of the device is not enough to cause permanent hearing damage. Some sources say otherwise (regarding 120dB in general - not specifically the Mad Bull product).

More news from Mad Bull coming later today as well. I have received an email with another new product. This new one is slightly less controversial, LOL.

Well put m102404.

I'd love to use this for "training" and outdoors as well. Could function as a regular grenade outdoors - as most fields have a proximity rule for grenades anyways (i.e.: everyone within 10-15ft of the blast is "dead", etc).


Off-topic though, here is the update for the other new product, a USB-powered Chrono! No, it wont collect data and output to a PC - keep dreamin'. USB is for charging only.

Hearing damage is cumulative to exposure as well and 120db is definitely high enough that if you were exposed to that in a work environment, the health and safety authority in your company would order you to wear ear protection.

I've got damage from a 22-250 going off and suffer from tinnitus in my right ear. Doc says any more exposure in that ear will make it worse. So for me, these devices are a definite no. Bad enough being on the back of an open air cab of a fire truck and having the damn federal siren screaming - I put in ear plugs now when I get on for a call.

so is jugglez going to get thyes new toys?

I've had a chance to see this device at ShotShow where Simon was proudly showing it off.

It's really nicely made and the report is pretty good. It didn't seem too damaging. I've heard dryfiring paintball guns which sounded a little harsher. The GSG-01 offers a sharp pop that I wouldn't consider to be overly damaging.

I do note that the Youtube vid showing the dB measurement had the grenade pointing right at the meter microphone at a very close distance (around 5cm when it went off). 125dB is a high noise intensity, but a distance of 5cm is very close for noise measurement. In open air measurements, dB decreases by 6dB for each doubling of distance.

The standard for most equipment noise measurement is 3' (IRC...) which is about 90cm which is 18x further than a 5cm measurement. I'm not sure how the applicable it is to reduce by 6dB for doublings from closer distances like 5cm, but if it applies well, a measurement at the standard 3' distance would come out at under 96dB (18x is greater than 4 doublings of distance 2^4=16).

At 5cm with the opening pointed at your face, the GSG-1 is a bit louder than a car horn at 3' or the racket at a rock concert. At 3' the bang exerts similar sound pressure to driving down the highway with your top down on your 'stang. I have no idea about the directionality of the GSG-1. It's got one exit port so I suspect that it will have some aspherical intensity distribution.

Properly specified dB intensity ratings should be stated with the measurement range.

To answer myself => RWA selling @ $99

Can this use the same adapter used on the other grenades?.
I'm not to keen on buying a whole pile of powerlets when I can
use what I have already.

For the sake of interest, I have a magazine at home (Special Weapons I recall), that had a couple articles on 9mm suppressor testing for pistols, and suppressed all sat in the 128-132dB range for sound level, but around 140dB unsuppressed.

airsoftparts.ca just got them in.

If you look at the video on the Mad Bull site, the grenade is right next to the dB meter as MadMax said. That'd mean you'd only get the full 120dB if your head was right next to it. I'd like to see a measurement maybe standing a foot away from it or something which would be the worst-case scenario for indoor.

Given the C$145 pricetag, I'm not sure how keen I'd be using these outdoors -- and I'm not fully convinced they'd be safe indoors (I'm not fully convinced they'd be safe outdoors, for that matter)

I suppose some impartial testing needs to be done.

Man, I'm glad I didn't sell my Peltor 6Ss. They actually might come in handy now!

if its co2, then cant the c02 pressure be regulated if its too much?

This IS why we have co2 regulator for our Madbull 203's right?

Just checked the videos...

I would not be afraid of having that go off close to me...

If it was not flying out of the screen for a good 2 seconds...

Anyone tought about it so far...

It lands on a hill close to you... You jump to cover, but the top of the grenade is pointing right at your head...

Too bad the day was hot and you removed your helmet... Now you have a piece of aluminium stuck in your head and a nice brain trauma.

Just what would be the point
 

of using this outside... What are going to do "pretend" it stuns you?

Really what good is it if it does not actualy stun you?

its nothing more than a gimic that will be soon ignored by players.

in a word useless outdoors

and from all the talk here.. useless indoors .. because no one would be willing to be in the same room with it.

so in a word.. useless....

you do not need to use powerlets with that CO2 adapter. we have installed that directly on a 20oz CO2 tank and it has worked flawlessly. You basically take off the powerlet cage and mount the adapter with regulator/gauge right on your tank.



Agreed! In the video, the demonstrator says to charge at 800 psi but only fill for 2-3 seconds. Doing that does not give you the full 800 psi but fills short of that amount.

When we fill our nades (XM108HP, XM204HP, XMPB4) we fill them for much longer. Basically set the regulator to whatever psi and watch the needle.

So why not just charge to a lower psi setting like 400 or 500 psi?

Great questions.

Would be wonderful if Simon from Mad Bull read these threads...

Defininently interested in getting one...i wonder if i brought a CO2 cartrige to my local store if they would give me a live demonstration :D.

i just got mine an hr ago and im having a hell of a time playing with this little thing. will post review later
