  1. Thanks for removing my double posts, moderators. They made me look like a fool :o.
  2. I am back, for 2 reasons. 1) to tell hangtight that I am sorry for being a :censored2:. I read my posts now, and I don't like what I read. 2) to get an answer on a question Google can't answer: "Hi again, people. I am considering to buy a MK17 from Vega Force Company. It has a solid exterior, good materials, and nice features like no exposed wires when you fold the stock. However, I do now know what's included in the package. Some people claim they got a full steel flash hider with the gun, some people say they have to buy it separately, and some people claim it's impossible to remove the orange tip, and that a flash hider won't fit on it. Also, some guns benchmark 400 FPS, while others benchmark 360 FPS. Last but not least, I heard that there is an American version that doesn't have all the serial numbers etc printed on it. My question is: where can I buy a VFC with all serial numbers and trademarks, that is compatible with a stroll flash hide, and how can I tell if he flash hider is included or not?"

  4. I excel at getting off on the wrong foot with people :( "Knowing the maths is one thing, but you need to make sure your assumptions are correct before you proceed." - words to live by! That sounds like some good advice. I have been looking at some VFC models, and they look very appealing. I haven't found any models by Tokyo Mauri tho, could I please have a link? Also, the part about big heavy gun is great. I do this to get fit xD
  5. No offense taken, you have impeccable attitude (unlike me). I will hereby call them BBs. I am aware that the BBs spin backwards and not sideways, and that it causes an force pointing upwards on the BB. With all due respect, I want to say that bullets are also affected by the Magnus Effect, but in a completely different way. If the wind is strong when you shoot, you must obviously adjust your scope horizontally to compensate for the wind, but you must also adjust the scope slightly vertically, due to the Magnus Effect. If you allow me to get back to the topic, my mind has changed. I still want a SCAR, but I have other priorities (most important on top): 1) It's an quality AEG. 2) No wires should be exposed when you fold the stock. 3) It delivers about 1.5 joules per BB (to not confuse anyone about fps, bullet weight etc). 4) It's <500 USD. 5) It's tan, not black.
  6. I read wrong. I though you said that a heavy bullet would always spin faster, and that is what I couldn't make any sense off. I do agree that a heavier bullet would require more backspin to maintain a straight line tho. Me being rude doesn't make it any less true. Where did you get <0.2s from? When it comes to airsofts, I have owned, and even made my own airsoft from scratch, and used it for many years with different kinds of bullets, hop up systems and so on. Please don't assume I am an idiot and tell me what I need, but rather help me finding what I ask for. If you wonder why I am rude, let me explain why. I get kinda pissed when people read only half my comment, and say I am wrong on some point, when we are essentially saying the same thing. It is a typical behaviour on forums, someone always has to pick on others, even tho they are saying the same thing, instead of helping out with what the OP asked for. Also, you call me a padawan, despite studying physics at the best university in Norway for four years, and desipte the fact that everything we have said to eachother is essentially the same thing. This is what really tilted me. Anyway. I am aware that you are trying to help, and I appriciate it. You have spent a lot of time explaining stuff, but that is not what I asked for. If I remember right, I asked for a SCAR, not a physics class. When it comes to airsofts, I have owned, and even made my own airsoft from scratch, and used it for many years with different kinds of bullets, hop up systems and so on. Please don't assume I am an idiot and tell me what I need, but rather help me finding what I ask for. EDIT: You said "Perhaps go and gather some experience before you are so dismissive of others." How am I dismissive? As I already said, we are saying exactly the same.
  7. That's something you pulled out of your anus. It depends on distance to the target. At some point the 300 fps won't even reach the target, but the 400fps will, which means it takes infinitively more seconds to reach the target.
  8. You say "Also we are dealing with a fixed energy system, at least in terms of linear kinetic energy". I say "if you double the weight on the bullet, the bullet speed will be divided by the square root of two" Given that E = m*v^2, we are saying exactly the same. You say "By if you calculate the energy decay of the heavier BB the maths comes out in favour of the heavier ball." I say "given that you have a heavy round that isn't affected too much of air drag", and "If couse, the issue with the wind can be compensated for with a heavier round" It is implied that we already use heavy rounds, I already agreed that heavier rounds helps out, because relative to the bullet, the atmosphere moves quite fast, and is a "wind". You say " A 0.3g round will reach 50m before a 0.2g round fired at the same energy" I don't know the drag coefficients for the bullets so I can't give any numbers about this, but it sounds very reasonable considering the balls are light weight and does not have an ideal shape. And I have never said anything else. You say " when it gets there it will still be travelling with a fair percentage of its initial velocity", I reply "no sherlock, it has a lower speed and thereby less drag, and a higher mass which means less acceleration due to F=MA." I really don't see who/what you are trying to argue against. If you read my previous commend carefully, you will see that we say the same thing. Doesn't seem like the padawan has much to learn at all, except for one point, which is how the higher bullet gets a rotation. My guess would be that the angular momentum would be the same for all bullets, which means that the heavier ones rotates slower. All in all, if you are trying to argue against the fact that a higher velocity isn't advantageous, there is something seriously wrong going with your logic. EDIT: I believe hopups are small rubber at the beginning of the barrel, right? In that case I am quite sure it's a non-slip situation with the bullet, giving every bullet would get the same rotation. EDIT v2: The heavier bullet will travel leave the hopup at a lower speed, giving it a lower rotation, which should give all the bullets the same angular momentum as I first said.
  9. I wasn't aware about what kind of gass you used for airsoft earlier, I am new to the whole thing. When it comes to ballistics, I am not new to it at all. I am on my fourth year on a master in Math and Physics, so there is no need to teach me about how a plastic bullet travels in air, we got professors to do that job. Even though you are right on all points, bullet velocity is a factor. If a bullet is twice as fast, it will use half the time to get to the target (given that you have a heavy round that isn't affected too much of air drag (don&#39;t know what the English term is, English is my secondary language). If it uses twice as much time, it will be affected four times as much by gravity S = (v_o * t + 1/2 a* t^2). This can of course be compensated for with a hop up as you say, as well as scope zeroing. Also, if it is windy outside, a doubled travel time will increase inaccuracy due to wind by a number between two and four depending on if the bullet reaches the wind speed or not. If couse, the issue with the wind can be compensated for with a heavier round, as you say, but if you double the weight on the bullet, the bullet speed will be divided by the square root of two, which is a huge difference (also, this will lead to twice the bullet drop due to gravity). In adition to this, the slower the bullet is, the easier it will be to dodge it when you see it coming. Sorry if I act like a prick, but I didn't sign up on this forum to be told that I don't know what I am planning to do for my living, but to get help with picking the right rifle on my terms, I am the one who is gonna pay for it in the end. Ps. Feel free to correct me if I am wrong about the physics part.
  10. Playing a few scirmishes sounds like a good idea, just to make sure I actually enjoy long range engagements with BBs. Also, after reading a bit, an electric gun seems like a very good choice, so thanks for that confirmation! When it comes to accuracy, hopups, barrel quality, length, and much other factors affects the final results, and one of these factors is bullet speed. The less time the bullet is in the air, the less it will be affected by the wind and gravity.
  11. Hey people! I am considering to pick up air soft as a hobby, and for that I need a gun. I don't have much experience, so I don't know which producers are good and which are not. I have been looking around for a while, and really can't make my mind. I saw a gas operated MK17 standard from WE-Tech that has solid reviews. http://www.evike.com/products/57579/ The only issues I have with this gun is that I would prefer a SSR if possible, and I am a little bit sceptical to using propane as a propeller (because it is flamable). I have also been looking at these two: http://airsoft.tiger111hk.com/p23585/WE-MK20-SCAR-H-Sniper-Support-Rifle-SSR-AEG-(Tan)/product_info.html http://www.evike.com/products/36060/ The problems with these are that number one has some ugly colors (might be just on the picture), and number two has 10% lower FPS which means 10% more inaccuracy due to wind and bullet drop. What I ask you about is a good SCAR-H, preferably an MK20 or at least a stock like this: http://www.americanspecialops.com/special-ops-weapons/mk-20-mod-0-ssr.php that fires at a high velocity, with a good accuracy, from a respected producer. The max price should be around 500USD for the rifle excluding everything else. Thanks for all your time, in advance :) Ps. I do not want a powerful gun to hurt people up close, but for accuracy purposes only. I got a side arm for closer engagements.
