how do those 'grenade launchers' work?

Post by b.lee.swagger » Fri Dec 25, 2009 1:23 pm

i am kinda curious on how those grenade launchers work.

1. how exactly do they work? i am under the impression that you fill if with gas and bbs, and then put it in the grenade, and pull the trigger and the trigger taps a 'button' lets call it, and the center of the grenade. so, the grenade is basicly a big centerfire rifle cartradge.
2. what is the matenence on these things?
3. is it a general rule that if you load less bbs in the grenade, the further it goes?

are they really worth it? sounds like unless you spend the cash and get a really nice one, they arent worth it.

They launch Grenades.

























Kidding.

They're pretty much the same as real greandes, except instead of high explosive death dealing, you get a shotgun-effect of bbs, or a foam rocket/slug, It all depends on what shells you use. I assume the maintence is the same as a GBB mag- silicone oil, keep a bit of gas in it to keep the o-rings from drying up.

In very general form, yes. The trigger releases a firing pin which strikes a "button" on the back of the grenade, firing it.

In actual function, they are nothing alike. An airsoft grenade is basically a very large GBB magazine, the "button" on the back in a release valve that allows gas to rush into the multiple barrels and fire BBs.

It might be better to thing of an airsoft grenade much like a shotgun blast. You pull the trigger and MANY bbs come flying out in a spray. You can pick a grenade based on how many bbs will fit in it.

To many variables. Each model of grenade is different, plus gas type used.

As little as 30 feet to as much as 300 (with lofting)

Also there are ones that shoot foam slugs, rockets, paintballs.

I like the Madbull 48rd shells myself. Load them up with 0.2g BBs and Red Gas and you'll get around 100 feet range with a 8'x8' spread at max range in 70° - 80° temperatures. Propane will work fine as well if you don't have any Red Gas around, but the range will drop to around 80 feet.

I have NO idea how you came up with that. The only real part about them is the look (which all airsoft stuff looks real), and how you load them (again, all airsoft stuff is like that).

A real M203 will be propelled out the barrel and explode on impact, or depending in the round, explode after a designated time (Star-Bursts, Flares, and some newer HE rounds).

But no, they act NOTHING like the real ones. The real ones are launched from the M203, the airsoft ones are a large group of BBs launched from inside the shell.

And no, you don't need anything to trigger them really. You can use your fingers to push the button down, not like a center-fire where you need a hammer and firing pin. By pulling the trigger on the M203, your pushing a rod into the button. Simple as that.

In Shodan's defense the function of most airsoft M203 shells is rather identical to that of real M576 buckshot 40mm shells :wink:
They don't load the same way, and the firing system is different, but the effect upon firing is the same.

I think the general consensus you'll find is that Madbull makes the best shells. The reason for this is their durability and superior bearing reset system. All airsoft grenade shells need their o-ring and bearing seal system reset each time after they've been fired before they can hold gas and be fired again. With most airsoft grenade shells this resetting process involves unscrewing the base of the shell a little bit and then screwing it back in.

This system tends to result in the 4 to 12 bearings inside the shell coming out of place every half a dozen or so shots, then you need to unscrew the shell completely and try to get all the bearings inside the shell situated just perfectly and keep them there will screwing it back in. This is a job that requires the patience of a god and is extremely difficult even for the most experienced airsmiths to do, especially when it comes to shells with larger numbers of bearings inside them. It can take an hour or more to do and is needless to say relatively impossible to accomplish on the field, so when your shell goes down you'll have to take it home and spend an hour or so trying to fix it (and then you'll only get another half a dozen or so shots before the bearings come out of alignment again and it'll have to be fixed again).

But with Madbull shells this is something you'll never have to worry about. Madbull uses a different bearing reset system that means all you'll have to do to reset it after firing is push the button on the bottom of the shell all the way in with a screwdriver, stick, or whatever you have around. And in all the years I've used Madbull shells (and collectively fired them hundreds of times) I've never once seen the bearings come out of alignment, so you'll never have to open up a Madbull shell to fix it like you would have to with (as far as I know) every other brand of airsoft M203 shell.

In short, spend a couple extra bucks and buy the Madbull shells of your liking. You'll thank yourself later when you never have to do the infuriating bearing resetting job that you'd have to do with any other brand of shell every half a dozen shots or so. As far as which Madbull shells to buy, it's your pick really. Less BBs will mean more range, more BBs mean less range. Most of their shells take green gas or red gas and some can even take CO2. Be aware that for the CO2 shells though you'll need to pick up a Madbull CO2 adapter with a regulator gauge that can regulate the CO2 pressure. Unregulated CO2 has around 800 PSI of pressure and for best results you want to run the CO2 powered shells between 500 and 600 PSI. Over 650 PSI risks blowing out o-rings, so it's important that if you run CO2 in the CO2 capable shells that you use a regulator to get maximum power without risking damage to the shell's o-rings. Madbull's 12g CO2 cartridge adapter with a built in regulator seems to be popular tool for this job but is a touch expensive at $75 or so. This might be worth it to you if you plan on using your M203 shells in longer range skirmishes though, as running CO2 at 500 PSI can just about double the range of your M203 shells when compared to use with green gas (provided you have shells that are factory certified from Madbull to be CO2 capable).

But anyway, check out Madbull's website HERE for a full list of their shells and to see the features of each shell. There's a lot to choose from that fire all sorts of kinds and quantities of ammunition and take various kinds of gasses. 6mm BBs, 8mm BBs, 10.8mm rubber balls, foam rockets, foam slugs, rubber slugs, and even paintballs. Keep in mind though that in most airsoft skirmishes the rockets/slugs/paintballs will only be usable for taking out hard targets like buildings and vehicles and should not be used as an anti-personnel weapon. Some of their shells (like the 10.8mm rubber ball firing ones) aren't listed on Madbull's page yet since they're pretty new but they are available at Airsoft GI HERE.


Hope that helps! :)
