Officer work, thanks. With the understanding that it doesn't really matter, I wonder how much rotational energy we have to donate before it has to come from the linear. Moment of inertia of a sphere, I, is 2/5 mR2 Rotation energy is 1/2Iw2, where I is as above, and w is the angular velocity (how fast it's spinning, radians per second if we're doing SI rather than fathoms-per-demihectare). I make that 1/5 mR2w2 We know m (e.g. 0.004kg), R (e.g. 0.002975m), now we just need to paint a BB with a battenburg patten and film it with a high-speed camera to find out w. Granted we're down at 0.0000000070805 w2 for a 0.4g BB, so we're not talking big numbers.

Oh, right. That reminds me, I have a stack of (claimed) 2Ah-ish 18650s lying around, and was wondering what would stop me from wiring a couple of them in series and throwing a Deans connector on.

Some form of cope, I think.

Sadly, they're pretty fragile. I'm not entirely clear on the problem you're having, but would note that the pump has to be fully forwards before the trigger will activate. Since it's currently stuffed, I'd give it a good old heave and slam in both directions. If you start disassembling, you'll end up with an awful lot of small parts and are unlikely to find replacements for any broken bits, so I'd avoid that unless Bullseye don't fancy taking the return.

Granted, it doesn't stop gravity pulling down, and the force to counter it has to be powered from the energy in the BB. What I'm curious about is whether it's all coming from the angular velocity (shouldn't reduce range) or is also bleeding it from the linear (will reduce range). (I assume here that we've got perfect backspin and site-limit muzzle energy for whatever mass of BB we're shooting).

Well, they do now. I didn't see a resolution to that case one way or the other, I'd assume their insurers settled at the courtroom door. And reminding people to fire until clear? Barrel socks will come to every site eventually, after the dry-firing fun and games turn into someone losing an eye. I've taken to wearing basic ballistic glasses in "safe" zones now too. No chrono, even after being on the sharp end of a negligence suit, is astonishing. While I'm the first to point out that pre-game chrono is largely just theatre, not doing any sort of chronoing at all is appalling, and I would have no doubt that some regulars will be rocking Section 5s or billion-Joule snipers. And I'm the last to suggest escalating situations, but I think that might result in a roundhouse swing with whatever RIF I had to hand. Did you bother even bringing it up with the site?

I'd always suggest a Maple Leaf 50 degree bucking and 0.28g minimum in any AEG these days. Omega nub, no omega nub, I'm back and forth on those, but all of my AEGs can over-hop 0.28g, even the MP5K with a somewhat ropey hop unit.

Have you considered the possibility that you've burst into a pub and are shouting "I LIKE BEER! WHY DO YOU ALL HATE BEER?" at a rather bemused clientele?

Nice one, I'd love to see what you come up with. I agree with keeping the bulk down, I trimmed quite a lot off of my original templates in order to get full mobility and articulation. In particular, torso armour needs to be truncated or articulated if you intend to crouch or bend. Me, or the horny xeno-girl? You know what... let's preserve the mystery.

Why do I get the feeling that you're under 18? Either way, you're fine, with or without supervision. He can loan or gift it to you without any issue. Ownership or possession in private has never been an offence and so doesn't need a "licence" (and he doesn't have one). Possession in public (i.e. you're on your way to or from an insured airsoft site) always needs a "reasonable excuse" (i.e. you're on your way to or from an insured airsoft site). In practice, what @EDcase said: don't let it be seen, and it won't be an issue. No larking around in the woods, or climbing on your roof for a photoshoot.

And the 2nd half of Negative Airsoft's workload are guns that have been worked on by other "tech guys". One thing about the KWA T10, I've spotted some sellers saying that they come in at "~380 - ~400 fps", which (rant about fps vs Joules aside) means they'll need to be down-sprung for UK use. Not just to come down to site limits of 1.1 - 1.2J, but legally as well, since anything capable of auto and over 1.3J ("375fps" in old money) is a Section 5 prohibited firearm, not an airsoft gun. If I were paying that much for one, I'd want to be sure that I wouldn't have to pay even more to have it re-sprung. The only reliability issues I've heard of with Tokyo Marui guns are when folk (owners or techs) meddle with them in some way, or (for the GBBs) run them on higher pressure gas than they're made for. That's not to say that you can't get a great VFC or a stinker of a TM, but TMs are Japanese made for the Japanese market, and have traditionally been the yardstick for reliability - if left alone.

Is that a "mine haven't" or "they are incapable of it"? Genuine question, I haven't so much as licked one.

We're quite friendly here, and where we disagree, it's generally respectfully, understanding that there's no single right answers. And there are few wrong answers or dumb choices either, because spending even three figures on any toy gun for playing pretend soldiers is such a daft thing to do in the first place. Whatever puts the biggest smile on your face is the right choice for you, that's the only criteria that really matters at the end of the day. I would steer clear of VFC, though. The sweary tech in that video up-thread, Luke at Negative Airsoft, seems to spend half his time sorting shagged-from-new VFCs. Lovely externals, but the internals seem to be either peaches or lemons.

They will be, until they're not. Given that the purpose is to create a dakka-dakka-dakka noise, is there any argument for doing that using devices that can and have killed people, when you could achieve the same result with an mp3 player and a speaker? If the critical immersion element is that they're creating muzzle flashes out of an open barrel, they can get sodded right off, because that's the bit that kills you when a pebble, shell sliver, wadding, or rogue live round joins the game. For context, I was at an English Civil War reenactment when a small smoothbore black powder cannon cooked off while being rammed. Poor show on the sponging, but the rammer was lucky/smart enough to be using good technique to "throw" the ramrod down it without gripping it tightly, which is why he didn't lose his hand entirely. However, the wad of grass that he was stuffing it with came out fast enough to turn his hand into cooked hamburger. Clear barrel "blank" firers are bloody dangerous, and I have no desire to be anywhere near them.

Well.... I am developing very mild tinnitus, and it's not from work or concerts. It's either from motorcycling air noise or from airsoft pyro. I almost always wear (and have almost always worn) earplugs when setting out to ride at over 40mph. Still, it could be that. Or it could be pyro. I don't wear ear protection in airsoft, but I'm coming round to think that I should. Personally I think that a .209 primer or Mk3 is sufficient indoors. If folk don't hear and take those, they're unlikely to take a 9mm or Mk5 either. That's earball overkill. And 9mm or Mk5 is all you need outdoors. Even then, a 130dB-at-1-inch Mk5 going off right by your ear outdoors will do just as much irreversible damage as if it goes off indoors. I will now tune back in to my scheduled "eeeeeeeeee" sound.

I cannot über-emphasise the importance of this. If you turn up with one high end toy with all the bells and whistles and then find that it's in a sulk, or shooting at 0.5J, you're going to have a bad day (or no day). I never bring fewer than two, and often as many as four primaries, whether as backups or loaners. If I were to have one AEG, then I'd agree with @herosharkthat (especially from your list) it would be the TM every time. Clean the barrel, then leave it alone, at least until you have a backup. Here's the thing, if you enjoy the actual process of playing airsoft, then you'll enjoy it with a £100 plastic fantastic. If you don't, then no amount of recoil or lock-on-empty will change the core airsoft experience of getting shot in the back of your head by your own "team" while you're knee deep in mud. I say this not to put you off, but hopefully to provoke some thoughts about what you want to get out of this hobby in the long term, after the first rush has worn off. I'll tell you what you won't get though, which is 90m effective range out of a 1.1J gun, no matter how trick the internals are or how big the price ticket is.

You could drop a feather and it would hit the ground at the same time, but only if your firing range is in a perfect vacuum. Be sure to double-mask so you can breathe.

Mmm, he does seem very optimistic. £120-ish worth of JG/GE G36C, abandoned, with some random spray paint on it (is that an attempt to two-tone a RIF?), plus a novelty-purposes red dot and a repro-vest. Battery has likely never been charged. A bargain at only £200, doubtless plus fees and postage.

These statement are both true, but I would stress that if you've got the backspin spot on, then more speed = more range. I'd even agree that at typical woodland engagement distances, getting the perfect angular velocity is more important than linear velocity (as long as you're getting somewhere close to 1J). And that if your hop unit and rubber can't impart perfect hop on a 1.1J BB, but can on a 0.8J BB, both with the same mass, that the 0.8J is likely to have a longer effective range. Just please let's be very careful to not make any sort of suggestion that that for 2 BBs from the same bottle, both with the same mass, and both with perfect backspin imparted, that the one with 0.8J of linear kinetic energy at the muzzle can or will ever travel as far as the one with 1.1J.

Hi Carl, we've all been there with that first game buzz. However, we've also seen the classifieds full of "as new, never skirmished" guns as folks' enthusiasm for purchasing exceeds that for playing, especially over the winter months. I'll skip the tl;dr physics-vs-airsoft-magic, and given your requirements, just point you at this. Now back to the scheduled "Buy a TM recoil" posts.

No, just count your blessings.

Oh, I'm surprised you didn't have your butler do the shooting for you.
