actually, for airsoft, most people use things that are basically impact rated ski goggles, if they dont use an actual paintball mask. in fact a lot of fields REQUIRE people to use a full face paintball-style mask

[jackssmirkingrevenge]

In airsoft, I gather the eye protection isn't nearly as robust....

I find that even cheap-o safety glasses will easily stop lead pellets (0.177" and 0.22") from a 12 ft/lbs air rifle. The impact might make the frame disintegrate so it wouldn't be pleasant, but the pellet will not penetrate the lenses, and they tend to dimple, not shatter.

As to the subject of this thread, I would say it's impossible to achieve safely, especially if the aim was to have the shell explode on impact and generate airsoft velocities from standstill.

I would be more sympathetic to the construction of a shrapnel type shell where a small charge is used to open the shell but not give them energy, this being imparted by the forward momentum of the shell.



Even this though would be an unsafe proposition for airsoft. If you want to shower your opponents with BBs, make a large bore shotgun

Don't assume that your homemade improvised gun will be perfectly accurate. How about a mortar style configuration (fire in the air) with a lightweight sabot carrying a massive number of bb's?

[boom shtick]

As far as bbs? maby 20 per round .If not than I will experament untill I get the right amount. Just enugh to not go broke but get a good hit probability
do you think taping two coffee filters together and filling it almost completely with bbs and flower would do it? it wouldn`t be solid,I might leave half an inch or so.

it`s going to be a m1a1 bazooka so I`m not thinking its going to be very aurate

All we are saying is that it is probably going to be just too much energy hitting someone at once.

Do a little mathwork for a minute.
Energy = 1/2 x mass x volume^2

That means that for a .2 gram airsoft pellet traveling at 395fps, the energy of the shot may cause bruising, but nothing more.

Increase that to 20 pellets (totaling 4 grams) and the diameter of your barrel (to get the volume), plus the sabot, plus the weight of the flour and that is a lot more.

To be safe, you will have to adjust the velocity lower (duh). But, it may be turned down enough to kill the range of the shot. And then, why would you want to take a shot at, say a bunker or tank (I'm assuming that's why it's made) at only 20 feet or so? You would obviously eat your fair share of 6mm plastic before you could even take a shot.

In other words, to make something like this safe enough, it's just not worth it.

On the other hand, if you had a shotgun type devise....well that's not what this topic is about.

Same thing here. However, I wouldn't trust them for a second impact from the same. They'll probably take it, but my experience is that the third shot almost certainly wrecks them.

I'm not in the habit of shooting them too regularly, but when a set of my goggles gets too scratched to still be much use, they go for impact testing. The results are revealing...

I agree with everything you guys are saying but would this idea work^

Yah sure it will work the question is getting it to work without hurting people.

I'd look at a shotgun like device perhaps davidvaini's burst disk launcher.

Largely irrelevant to the point I was making.

I asked if the projectile could dislodge the glasses/mask/whatever. The question isn't whether or not the projectile can penetrate the mask. Designing a projectile that couldn't penetrate would be pretty straight forward.

The question (again) is whether or not the projectile can dislodge the mask. For a large projectile, this is the more difficult design goal (as opposed to mere penetration).

After all....

We're talking airsoft. We're talking a (non-lethal) firefight.

So you hit this guy in the face with your bazooka. Nothing penetrates, but it does knock his mask off.

He is now standing in the middle of potentially hundreds of itty bitty projectiles flying around and he has ZERO eye protection.

Ooops.

Again, it's not only penetration, but security of the entire eye protection system that is required.

If you fire something like that around then expect to be punched up.

Why not just put a piston in the barrel which is stopped/tethered that accelerates the bb's?

because I am trying to make this thing as realalistic as is possible so I`d want seperate missiles

why not somthin like this

just in a 2inch bazooka break barrel that the best way trust us dont stick a sold progetile in there u could kill or hurt some one
want to hear a story we were playing air soft my friend bill wore these cheap sun glass.My friend not saying his really name shot a 3 round burst hit his glasses they shatterd.He lost his vision completly in one eye the other is badly damaged what would happen with a 2in projetile btw person that shot bill was aiming for his chest but he forgot his hop up was up so it hit him in his eyes. true story d
ont use solid projetiles, also always were paintball mask while playin airsoft ore paintball.

You won't be allowed it in any proper game.

No airsoft gun fires packages of pellets, the point is you only launch individual pellets with a certain energy at each other

Firing what is essentially a beanbag round is out of the scope of the game and the speed you'd have to fire it at to be within energy limits would be pathetic.

It also doesn't matter if you intend to aim it directly at someone or not, if you're allowed to do it everyone else has to be allowed to fire beanbags too.

[boom shtick]

I don`t usualy play in any organized game, just me and some freinds. And to answer twizi What I maent by realalistic is fireing a misslewhich explodes upon impact is how the m1A1 worked, I`d like to get as close to that as possible. Thanks for the link though
