  1. Yarp, the feeding is problematical. Mine would try to feed a whole shell full of BBs into the barrels, that sounds similar to what you're seeing. You'll hear folk giving the iPhone excuse - "ur holdang it rong!!!" - but that's victimblaming. When I finally got it all apart (being too dumb and stubborn to send it back) I couldn't see what the problem was, so I just gave everything a good wiggle and silicone lube and put it back together, and it's been fine since (so I wasn't donging it wrang). They're really not intended to be stripped down though, there are dozens of tiny screws going into cheap plastic, so I'd agree with just returning it.
  2. True, when given a barrel you can be the fish, or the shooter.
  3. Getting shot in the face by a sniper rifle at 30cm is safe?
  4. Really? Nobody's been offered out IRL yet.
  5. What gave you a contrary impression? You're OK with a complete lack of chrono?
  6. I used 7mm rolls, commonly sold as "anti-fatigue" mats. For example: https://www.ebay.co.uk/itm/333562735362 7mm doesn't sound like much but it's robust enough and easy to cut and shape with a heat gun, and is ideal for what I've been doing with it. I've got some square panels as well, maybe 10-12mm thick, which would be fine if you wanted to make big, solid, structural shapes, but I've not needed to use them.
  7. Well, I'm not aware of any other sites where a child has been blinded. I'd actually be fine with barrel socks, if they were actually enforced, starting with the site owner, marshals, marshals' mates, and regulars. Are they though? The only reason I'd go to that site would be to run a 4J sniper and nut-shot anyone wearing a hi-vis.
  8. I make that 0.0001261148327138J of rotational kinetic energy, or a lot less than that required to hold it up, so it's got to be leeching that (small) amount from the linear. Insignificant compared to the drag, I was just curious, unlike some peasants in here.
  9. 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.
  10. 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.
  11. 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).
  12. 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?
  13. 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.
  14. 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?
  15. 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.
  16. 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.
  17. 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.
  18. 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.
  19. 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.
  20. 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.
  21. 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.
  22. No, just count your blessings.
  23. Oh, I'm surprised you didn't have your butler do the shooting for you.
  24. Ackchyually, we had a good bun fight a while back about how we should be using direct measurements of impact energy, which would make the entire fps / BB mass issue moot. Sadly, I couldn't find any cheap solid state components that claim to be able to measure the sort of small (energy and size) impulses that we'd be getting with anything like the required level of precision. So then you're left with trying to hit a pendulum and measure its swing, and it all goes a bit Rube Goldberg.
  25. I'm backing slowwwly away from one of them, I think it's a bit bitey.
