Memes are back on the menu, boys. Eh. 20,000 rifles, they're just putting the tip in at the moment. That Vortex optic though, I can't wait for the "need dat 4 airsoft!!!!!".

Nobody called you a scammer. Please feel free to check. I'd go with "geezer" or "chancer". "Puckish rogue", perhaps. Either way, I won't be seeing any further seethe and cope from you.

Ahoy and welcome. Challenge accepted.

Good for them. Of course, if you want to know what a gun is actually producing in game, where it matters, there's only one way to do that.

Yup, @sjhirst's image above appears to be a true truth, see https://www.postoffice.co.uk/mail/what-can-i-send - it does warn about delays while they grasp your Glock, but should get through eventually. That's great news, it looks like we have a viable option to PF48. PF48 caps (or capped) compensation for shooty things to £100. To be honest, on the few occasions I've posted (cheap) RIFs I've just sent them by whatever courier was cheapest, marked as sporting goods, on the basis that I doubt Hermes (or "Evri" as they've rebranded) really gives a stuff what they're carrying as long as it's not dripping or ticking.

That, really. I have the typical airsofter B6 V1 and it doesn't even do internal resistance guesstimations. I'd trust your own calculation more. I mean, assuming that is a 1Ω resistor.

To be a bit more helpful (teeth firmly gritted), the quality of answer you get is determined by the information in the question. The more you can tell us about the actual make and model of what you're interested in, the better. Also, what you expect to be using them for, e.g. woodland, CQB, impression kit, sticking up a bank.

Mmm. I'd normally be all caveat emptorish, but his/her/zeir only interactions here appear to be buying and selling. I'd question the value of that, especially if ze's going to be flipping prices to the moon.

Beats me. The ones we've been pointed at appear to be more expensive than ABS or PLA. It's baffling, but... airsofters.

The thing is, despite it being a phenomenally bad idea, it wasn't actually an offence, as they did have a reasonable excuse, and could presumably prove it. Flipped arsey-versey, our budding Quentin Tarantino here is legally just fine to get his hands on a RIF (assuming 18+) but I rather hope that he doesn't.

Why imagine?

Well, shows what I know. Using a cheap and admittedly uncalibrated luggage scale, with a Silverback 100 "Newton" spring with about 4 loops cut off, I'm seeing a 17kg (166N) peak from a slow, careful pull, and nearly 25kg (245N) peak from a more realistic sharp pull. It still doesn't feel anything like that, mind, because it's a short, smooth pull. Makes me want to try a Rapax 2J+ spring which claims a lighter pull for the same boing. Out of stock at Skirmshop, of course. £21 delivered from Serbia... except if I get mugged for VAT, and the mugging to pay for the VAT mugging.

If we're going to be technically correct - the best kind of correct - chronos only measure elapsed time, then calculate fps from that. Joules is just another step down the line. Let the silicon take the strain. It seems obvious, but I've yet to see it up here. Hmm, I might start laminating them and sticking them up at chrono stations, like some sort of efficiency vigilante.

Indeed, I'm all for it. "M" ratings are intended to be helpful, but given the wide range of variables (air seal, cylinder to barrel ratio, BB mass) they're really just a relative scale, and only within a manufacturer's own range. The Silverback springs just give a single Newton value - I'd assume (by which I mean hope) that it's at the compression of a fully cocked and locked SRS or TAC-41. Even at that, with a 100N spring in mine, it doesn't feel like I'm lifting 10.2kg to pull the bolt. Hmm, that would actually be measurable though... ?

This is nothing personal, but we have zero self-interest in helping you. This is a forum primarily for people who use airsoft guns for their intended purpose, the one behind the defence that we enjoy, and which could be removed on Ministerial whim at any time if RIFs are abused. The very fact that you asked here rather than on a theatrical forum suggests that your intentions are not what you claim.

The great thing is, you'll then get to see some real guns up close! https://www.standard.co.uk/news/london/student-filmmakers-handcuffed-by-armed-police-while-making-movie-on-streets-of-london-a4282551.html

Sadly, I rather suspect that we're going to see it relisted soon enough as "Mint condition, shoots like a laser, barely out of the box."

Or in Joules. And Silverback springs are measured in Newtons. Why can't we just all agree on a sensible value like ergs, or angstroms per femtosecond?

Maybe. But is it quicker to press a button two or three times than to look at a number, than to look at a different number, then do the finger-shuffle on a spreadsheet to find the first number? If I'd ever seen a site that had printed out just the limits for each BB weight and gun type, it would make more sense, but I've yet to see that. It's either a generic chart where they're looking up a Joules number anyway, or worse, the marshal's got something on his phone to work it out which is almost certainly slower than changing the chrono setting. Could be wrong, but it's marginal either way.

Given the currency devaluation / inflation situation, and (literally) half of China being locked in their pods at the moment, I'd only expect that to go up, sharply. They're not going to get any cheaper or more available.

Yes, it should be an M90, with a spare M120 in the box (although it may be in an opened "M90" wrapper). The M90 should be usable, and notionally an M100 should get to close to UK limits. However, it's entirely down to air seal and to some extend the BB weight you're using and whether your local sites chrono sensibly, or with 0.2g. You may be lucky and get close enough as it is, or want a 95, 100, or 105. I'd play with it first and see what it chronos at with the BBs and hop that you'll want to use, then take it from there. A cheap chronograph will save you a wasted day if you come out a bit spicy. It's easy enough to cut a spring down once you know what it's producing.

Snap. Seems fairly decent in garage testing, with a short, smooth pull. I'll also be testing next Saturday - race ya.

Er, well, yes. They're chronoing in Joules, but living in denial. There's a practical argument about it being slightly quicker, maybe, to cross reference an fps number on a chart than to change the setting on the chrono, especially if someone is using an unusual weight. My main issue is with still thinking and talking in terms of 0.2g and 350fps as a default, which is now an edge case for woodland. Thinking about it, the one weight that you probably don't need on a chrono for woodland is 0.2g. Really, how many people are still shooting that?

If the spring is loose on the guide, some heat-shrink can snug it up.
