good to know- mine's the cybergun version too.

Ahh yes, sorry i forgot to grab pics, here's some potatocam ones:

Like i said originally- cant be arsed doing it properly. Asking for bb weights and chrono'ing on energy will catch the honest folk who dont understand physics, as you say cheaters gonna cheat so at least use the method that requires people to be dishonest and follow up by catching people in the field. Like i said in my original point- i'd rather get smacked by a gun running 329fps on .2's than one that runs 320fps on .2's but 290 on .4's. Some versions of the mk23 and the we makarov comes with one, the makarov one is a seperate barrel extension though so it's pretty visible when you pull it off. In any of the cases of a barrel extension they tend to push them way over any reasonable limit although accuracy tends to go out the window. Not saying they're all bad, on an aeg or without a barrel extension they can look cool and for some gun types even make a big difference to noise.

He's referring to the type that has the extension mounted to the suppressor. Easy to check if it's mounted and sure folk could put them on post chrono but that's no more difficult than switching guns midday, switching bolts in a sniper rifle or twiddling the regulator on an hpa, which is why the follow up of keeping the chrono on you and random spot checks in the field is also important. Sure cheaters gonna cheat, but the whole .2's chrono'ing thing can accidentally let even honest folk end up running hot.

There's never any guarantee, but as pointed out at least if your using player weights and keeping an eye out for certain types of guns then you'll catch out the honest folk who genuinely dont understand what they've done. If you dont have enough time to do it for a large group then the obvious follow up question is how many marshalls are there and how the hell do you hope to police any other aspect of airsoft cheating?

yep, this is a case in point- you didn't even realise you were running hot. i made the same mistake although luckily i did think to chrono it before chucking the old barrel so i now have a long pistol barrel sitting around that i can't use. would have been worse if you'd been running heavier ammo as a longer barrel is more time for joule creep to take effect.

you check the suppressor, if it's got a barrel extension in it/under it it'll almost certainly be hot. better than not checking at all......

Because green gas pistols aren't as loud and scary as co2 pistols so they can't be hot. At least that seems to be as much logic as any site i've asked has put into it.

Yeah that's probably the easier option option as you can see the whole chrono'ing thing is a contentious issue

You only have to keep an eye out for the gas guns and pistols with suppressors and keep a stash of heavier ammo to test those players. Aeg's don't really joule creep to any significant degree without a lot of pre-meditated setup so the ol' .2's is fine here, as are most pistols with standard barrels.

Its not impossible to test for joule creep, i've just never seen a site that could be arsed doing it properly. Case in point: lets say i go to a site, 328 limit, chrono the polarstar and get 328 328 329 on the .2's they put in the mag. "Sorry she's hot you can't run that" "It's cool, i'll turn it down, you can even tourney lock the reg if you like" So i turn it down, hit 320 on .2's so its under the limit, they lock the reg Then i drop some .4's in and she's putting out 290fps or 1.55 joules Then i ask "do you chrono pistols?" "Only co2" "That's cool, this one's green gas" What they dont realise is the pistol has an extended barrel under its suppressor and puts out 2j on .4's Thing is, that according to the site rules i havent broken any. I chrono'd honestly according to what i was asked, and yet i'm running around with hot guns. Whats worse is that because so many airsofters don't understand how these things work its entirely possible for me to have had no idea that's what i'm doing and i could genuinely beleive everything's fine. Dunno about you but i'd rather be hit by someone running 1j than someone running 1.5j or 2j from a pistol. Now what actually happens is i rock up at the chrono with the polarstar and say "i'm running .3's" because that's what i'm running, the concientious sites then set their chrono to .3's and i chrono to 1j and i get very tetchy when i see gas guns running suppressors because i know what that could mean.

Probably dumbfoundedness at the idea that its something you can do. But it is a fair point, nobody calibrates their chrono's and therefore its hypocritical for them to claim they can identify to an accuracy of 1fps, especially when more often than not they then ignore joule creep/dont bother chrono'ing green gas pistols. You dont seem to have got my meaning, 1fps means fuck all when it comes to airsoft, especially if your using a test method that ignores joule creep.

Bb's dont fly straight, you'd be better off zero-ing on site.

There's various calculators out there, take a look at the tutorial section there's a spreadsheet i made up or just google fps calculator for something a bit flashier.

Personally i would test for energy, so with hop set to whatever you normally shoot with, on the weight of ammo you normally use then measure for joules. However some sites can be incredibly picky and insist on the whole using .2's with the hop turned off and 1fps over the limit is not allowed. If a site pulled that on me i'd be asking them for the physical basis for such a testing procedure and a copy of their chronograph's calibration certificate. Some sites can be the opposite, not understanding that for example 328fps on .4's is not the same as 328fps on .2's And that's before you even get into joule creep, or the old "we don't chronograph green gas pistols" chestnut.
