Pseudotectonic

To cover the blue, you need to have evidence of you playing airsoft: Name of the site (needs to be listed on the UKARA website) Your attendance at this site This could be booking receipt/email, plus a selfie photo of you at the safe zone with an identifiable logo or sign, or something like that.

what gears?

https://www.legislation.gov.uk/ukpga/1980/66/section/161 "and in consequence a user of the highway is injured, interrupted or endangered" Unfortunately this might stick

Can you post a picture? What sort of location is this? No paint is really able to withstand constant wear, even cerakote can wear out over time So instead of looking for something that last forever (which doesn't exist), maybe you need something that can be applied easily, like a paint marker pen that you keep in the bag Or 3D print a replacement part with a different colour plastic

If you google "gun room interior design" there are loads of impressive looking examples, the vast majority of them seem to follow this formula: Cabinets lower half Display racks upper half Colour / material coordinated Integrated lighting In your case maybe it is a matter of organising what is below the slatboards, maybe with some cabinets Maybe convert to a vertical gun rack for better efficiency Or even remove half the wall rack and put in taller cabinets, since half of your wall rack is stuff that shouldn't be on the wall anyway

I concur With 13:1 this will get you to just under the PME ceiling which is optimal Btw I was thinking those x ms delays in brushless may be related to the software denouncing method, and there is a way to completely remove this delay if they change the code to "register immediately upon voltage detection and ignore input for the next x ms" rather than the usual "wait x ms for the voltage to stabilise before registering"

i wonder if a bolt cutter can cut it

If the battery and wires were heated up, first of all there is a short or jam that caused it, and secondly your battery might have been overdrained during the heating so it's gone flat

How was the weighing done? I mean are they certain the accuracy of the scale is within ± 0.001 g? Also sample size = 30 is often used as rule of thumb for statistics, it's usually good enough to locate your normal distribution i.e. central limit theorem

It appears to me that UKARA has a monopoly of lobbying power because they hold the secret sauce data of the airsoft market. However because they are not really an airsoft association they do not have the capacity to take on the role of one. A full fledged airsoft association should really be doing a number of stuff even during "peace time", e.g. PR and promoting safety and improving the hobby etc (see suggestions from GPT above). So that the public perception of our hobby does not depend entirely on external factors such as whichever party is in charge. In other words, the toy gun illuminati might be too good at being secretive it is unintentionally trapping the hobby in the fringe zone it originated from.

@Asomodai While I do not doubt your credibility, is there an "official source" where this info can be checked? BTW I just noticed a fun fact, UKARA charges a £300 annual fee from each of their retailer members, there are 64 retailers on their website so this is a ~£19k fund annually for maintaining the database. So I assume this is all going to Fire Support?

Amazingly the story of UKARA is truly becoming lost history because their operation is so obscure. Here is a brief mention of it being an Excel file sitting at a site called Ironfoot Airsoft that used to exist (near the GCHQ site), but the farmhouse is now demolished. So there is really no solid up-to-date information of exactly who and where and how UKARA is maintained.

In the spirit of larping we can actually wargame this out: In what circumstances would the VCRA be amended to not allow RIFs being sold to airsofters? (I'm surprised GPT actually came up with some half decent answer, for comprehensiveness I'm editing collating the key points below) Can you suggest actions airsofter can take to prevent these items This AI is not bad

This is going back to the discussion of having an association/federation/facebook group Who should be keeping track of and able to pull out numbers about the airsoft economy

Melamine foam (aka magic erasers) might be a good alternate It has rather high NRC and is also in some brands of acoustic panels With PU foam there are many grades and weights and whatnot and not every type is good for absorbing sound (some are), whereas melamine foam seems to outperform even the acoustic grade PU foams especially towards the higher frequencies, which is what we want Magic erasers are rather cheap and easily available, and it is safe to handle and very easy to cut to shape, just get a pack and cut out some round sections and stack them You can even scrub dishes with it

The more I think about it the more I feel air diffusion does not really matter, because the air pocket will seek the path of least resistance and this will be around the BB and in front of it. When the BB is just entering the suppressor, the clearance will allow the air to go around and this inrush pressure will hammer on the first few mm of material around the barrel exit, but will quickly diminish as the air go around and in front of the BB, rather than hanging around looking for openings in the foam/mesh/wadding. This will have already finished happening before the BB is even a few mm into the suppressor. Therefore the fill material does not really need to diffuse any air, its only job would be simply to absorb the shockwave, but not necessarily absorb any air volumetrically. Therefore it can be a solid material. Now in order to absorb the shockwave and not echo or transmit or reverberate it, it needs to be somewhat flexible I suppose. If one were to isolate this shockwave in audio it will probably sound like a high pitched crack, because it is essentially a sharp hiss of air that is compressed into a very short time, it will be in the upper frequencies because dimensionally and energetically it should not produce any component in the lower frequencies. What fill material (at 10-12 mm thickness) is best for muffling high pitched noise (say 2 kHz to 20 kHz)? If we go by this chart we may be looking at some sort of "fiberglass board" or "sprayed cellulose fiber" (look for a high Noise Reduction Coefficient at high frequency ranges) Now we don't want to be blowing fibreglass particles around so we can rule that out Cellulose on the other hand seems to be the best material for the job but might be impossible to put into a can and keep it there (not to be confused with spray foam) So the key might be instead finding something that has the next highest NRC, perhaps carpet tiles

oh nonono SHS_hightorque_is_not_hightorque.png SHS high torque is 16 TPA, it is low torque Get a 22 TPA if you can, and when you are ready pop a 13:1 in there, or better yet a Perun Hybrid and turn on precocking

https://www.burymercury.co.uk/news/24345047.second-report-weapon-seen-bury-st-edmunds-town-centre/ "air-powered ball-bearing weapons" why do people always come up with new nicknames for airsoft

If the 25 days are well paid like a proper summer job then I can see people volunteering, otherwise they'd think it's authoritarian being forced to working for free when the economy is beyond fucked up

Let's do some maths Let's say we want to completely contain the pressure wave within the can so by the time the BB exits there is zero difference in air pressure inside and outside the can, meaning the ideal air volume in the can plus the volume of the barrel should roughly equal cylinder volume: Vcan + Vbarrel = Vcylinder The typical cylinder volume is what, ⌀ 24 mm x 50 mm? or ~22.62 cm3, if this is 3/4 ported it becomes ~17 cm3 If my barrel is a 270 mm barrel, ⌀ 6 mm x 270 mm is about 7.63 cm3 (so the ratio is about 2.23 it seems but this is irrelevant) That gives me about say 9.4 cm3 of air that needs to be diffused inside the can Assume we are using a replica of a 556 can with an external size of say ⌀ 38 mm x 157 mm, subtracting the body thickness and a layer of butyl tape lining of say 2 mm and fittings etc we have an internal volume of say ⌀ 32 mm x 110 mm or thereabout or 88.47 cm3 of total space inside Of course we need to leave a clear corridor for the BB to go though and it cannot be so tight, if it is ⌀ 10 mm x 110 mm this is 8.64 cm3 out of the 88.47 cm3 that needs to be kept clear, giving us say 80 cm3 of diffusion zone available But this BB clear corridor should also be included in the Vcan so this ⌀ 10 mm x 157 mm or 12.33 cm3 is already bigger than the 9.4 cm3 volume we need to normalise That means, the foam fill material within the 80 cm3 diffusion zone is really just handling impulse pressures And if we sketch out the wavefronts we can see most pressure is probably in the beginning 1/3 portion of the can, accordingly we can use a dense mesh here, and use a more open mesh in the later 2/3

Nah if it works, it works, but if it happens to get hot during the game, you know why

PME means pre-mature engagement, that is when your ROF approaches about 30, your sector gear will be too fast and will try to engage the piston while it is still travelling forward i.e. the sector will slam into the middle of the piston rack and chewing up gear teeth Since SHS "high torque" is actually a 16 TPA high speed, I think with 11.1 and 13:1 gears it will probably go over 30 RPS, hence the PME risks

Good point about gradual reduce of the pop, so perhaps the whole thing should be filled with some sort of open cell foam that is high enough porosity for maximum diffusion So perhaps there is some merit about the common paint roller insert Butyl I guess is nice as a middle damping layer between materials, or a lining layer, but not sure if it is the best interface for the air borne noise, because maybe the smooth surface isn't as good as an open cell structure for diffusion of the pop Maybe if you roll up some thin gauge wire mesh to simulate an open cell structure it would be very effective at diffusion and absorption?

Oh no not another, SHS high torque is not high torque But yours sounds nice But don't be tempted to go 11.1 with this, you will get PME

Just theorycrafting here... just a sketch to note down what we have to deal with... 1. Vibration damping: We know the case will resonate and vibrate from any sound from inside (air expansion) and from the barrel (piston impulse) so the case need to be treated to become a composite material so any vibration is deadened rather than resonate, can be achieved with a lining of vibration damping tape or with similar principle 2. Air gap: To limit energy transfer from inside to the case, maybe we can leave an air gap so all the air expansion is contained and processed inside, rather than transferred outside to the case 3. Absorbent material: We need to convert as much sound into kinetic energy as possible at this layer, maybe a heavy and absorbent material, maybe some sort of rubber or silicone or something along those lines 4. Air expansion chamber to match the cylinder volume ~1:1 so the space can be filled with as much absorbent material as possible (for the highest conversion ratio possible), geometry to match the air expansion pattern, and/or optimised for absorption (depending on how the absorbent layer is made). This area probably needs to be towards the back. 5. The "exit tunnel" of the BB should be towards the front so any leftover sound from the air expansion zone can be limited, we just want the BB going out but with minimal air pressure i.e. sound. TLDR we need to convert the vibrations into heat as much as possible, and we try to do this inside while limiting any transfer to the outside
