what is the max fps for and airsoft wepon in game

All weapons:
 Up to 320 FPS – no engagement distance but use common sense, and apply the bang rule where possible
 320-420 FPS – 10m engagement distance
 420-520 FPS – 15m engagement distance
 No weapons above 520 FPS are allowed
 A +20FPS tolerance may be applied on a hot day.

Usage of weapons exceeding 320FPS is restricted to qualified members. To qualify a player must demonstrate to the appointed weapons instructor’s satisfaction the appropriate handling skills, distance judgement and maturity required.

That's what it is at the moment, but we are currently reviewing limits hoping to simply the system further. I think that there may be distictions depending on your gun. SEGs have an upper limit of (total guess here) 400fps at the moment (could be 350 though), bolt actions can go much higher (up to uh, 400 as well, maybe 500?). Pistols don't have a limit as far as I am aware. I think you can have a higher power GBB or SEG rifle for snipering so long as it has less than 30 bb mag and a scope.

That's all from memory and the definitions are not defined fully yet. We are hoping to review the rules and put out a booklet giving ATA rules in full soon.

Current proto-rules put it a little differently.

For CQB only designated sniper or support may be in the 350-420fps range.

In CQB no weapon should exceed 420fps.

420-520 FPS is 20m engagement dist. for designated snipers only.

No weapons above 520.

Sniper weapons are recognised sniper weapons, not SEGs, must have an optical sight. A semi-automatic sniper weapon must have a real cap magazine.

Support Weapons must be fired from a fixed position.

Weapons exceeding 350 FPS are restricted to qualified members. To qualify a player must demonstrate the appropriate skills, distance udgement, and maturity required to safely use higher FPS weapons.

And that, is how the current rules are. These are proto-rules and so may go through a bit of tweaking before they are implemented.

There is talk of making ATA 'CQB level' only. Meaning a upper limit of 350 for SEGs and 420 for snipers and support.

yourr thinking to much cqb and like some clubs we look more like


up to 350fps anything no engagement just conman sense
350fps-410fps limited to DSRs(SEG sniper rifles) and Light machine guns
410fps-520fps bolt action rifles only

but this needs to be talked about more as Tim has said just try stay under 350fps for a SEG unless light machine gun and you will be sweet

does that depend on the propellent?as in what you are fireing?and are there any restrictions on what you use to proppel your "prjectile" as such?

No? Unless, what you used to propel the BB went flying with the BB. But that's crazy.

It doesn't matter what the propellant is really.

so if the super wicked flame burnt there face off it wouldnt matter? cool.
um say i fire a pillow does the fps limit still apply?

Well, the reason we have the FPS rule is cos it means we have less mathmatics too use. The goal is to not have BBs go over about 1.6 joules or something. Weight is included in that. So a pillow, weiging a lot more than a bb, will have to travel alot slower.

Oh such a technicaltopic. a nice little picture diagram would make it really easily,someone shouldd raw one. Someone likt timmy with his artistic skills and such.

just an important point..... this is actually a measurement of energy. So to measure energy we check all guns fps with the standard .2g BB for consistency. You can use lighter or heavier BBs if you want but the gun is chrononed with .2s. Eg: your gun might clock 340 fps with .2g BBs and 450 fps with .12g BBs, but thats fine. The faster but lighter .12g BBs will only have the same actual energy as the .2g BBs, and will travel a lot quicker over short distances, and the opposite is true for heavier BBs.

*gets ideas*

I am thinking of upgrading my gun to 410 cause it is with in the rules that people play, so why not.

You would need to cosmetically alter your gun Jono. And have to fire from a stationary postion. But seeing as you'd end up with a badass RPK it'd be worth it.

Sort of SEG sniper rifle can count for over 350-410 but don't think would count AK as it one I mean I count a M14, SVD, SR25, G3A4, PSG1, SL8. But we will see would be complosary for a side arm. BTW RPK would need a longer barrel, bi pod, bigger mag at minimum.

i dont see why you need to lie down for the LMGs you can fire a real one standing.

The need to stand still is related to the higher FPS. You're far less likely to break the minimum engagement distance rule if you are stationary than if you are moving around.

Was interesting to test fire a gun chronoing 210 fps, and yet it still had suprising good range. 420 fps is literally double the muzzle velocity, yet i doubt it would add more than 25-30% to the overall range.
We are going to have to test this more thoroughly, but ive chronoed a little bit at 10m and its fact that increasing muzzle velocity has diminished returns. Or to put it another way, if a gun doing 250 fps goes X meters(about 40m), then 350 fps will go X+10 meters, and 500 fps will go X+20 meters. This is becuase the drag increases with the *cube* of velocity, while energy increases as the square of velocity. This multiplication of energy means that the energy at close ranges is much higher than therefore we have minimum distances.

should add that even thout the extreme range doesnt increase by as much as you might like, the bb does travel a lot faster in the near distance and gets to the target quicker, so it is worth it from that point of view. Also the higher fps guns can use heavier bbs which carry energy further better

not to mention due to the increase in mass and therefore inertia the bb is less affected by things like wind drift. (i thought i would get technical as everyone else is)
