  1. Understand though, that when the shot trajectory takes up that much vertical space, you start to run into problems like the scope being unable to zero at a particular range, and the field of view of the scope not covering the BB for it's entire flight. When you have that kind of arch, you need to start to think about the slant of the scope in relation to the bore of the barrel. It's not impossible, it's just that it's a new thing that people aren't experienced with. There are a lot of logistics to work out.
  2. Triggers that hold really tight tolerances usually jam anyways. Loose tolerances can be very beneficial in terms of reliability in a lot of mechanical systems. The perfect example would be the AK-47
  3. People have gone over the math before. The main downside to the physics of the idea - formalities aside, is gravity, and the inherent low velocity of airsoft rifles Without lift, a BB or similar projectile would drop 5 feet in under 200 feet, making the arch of the shot very extreme.
  4. Regardless of the title, an HPA sniper rifle would be a better platform to work with
  5. Yeah the biggest limiter is definitely mass. Mass and velocity. Chris
  6. To the OP: Why was I quoted, and how is it relevant? No.
  7. Another option for hop up units is to make the unit fixed, but have different grades of rubbers. The mildest would protrude the least into the barrel, and the most aggressive would protrude the most. That way, no screw is stretching and distorting the rubber, and the stability of a fixed unit is achieved with the addition of flexibility.
  8. Unfortunately, the physics don't work out very well for that option. The BB doesn't fly fast enough to get out past much farther than 150 feet before gravity brings it down. The concept of hop up creating lift, extending range is an extremely critical technology for airsoft.
  9. Suprafish, Yes, buckings will have to be redesigned. sniperx2s, That is a very good design philosophy, one that you and many others, including myself, share. The guns now have a lot of parts, and the reason for that is cost. It is cheaper to have a small, thin inner barrel housed in an aluminum outer barrel than it is to have a solid, one piece barrel. It's cheaper to have the bolt riding on plastic rings than it is to hold the precision of a properly designed, metal on metal contact. It's cheap to make the guns the way they are now, and it's not cheap to make them right. The manufacturing game is to see which corners you can cut to bring down the price of your product to make it more affordable. An example would be the receiver of an AK-47. It's manufactured by stamping a flat plate of steel into the correct form, which is cheaper than milling it from solid billet. It's a compromise. They can make those receivers fast and cheap. They can also mill out an AK-47 receiver, but it will be more expensive. The milled receiver will be better, maybe not by much, but better. A common phrase is that a stamped AK will last 2 lifetimes, and a milled AK will last 3. Both are very good, but the milled AK is better. If we are really trying to push the envelope of accuracy, why would we compromise? Why would we cut corners? If I were to design a gun, it would be over-engineered, and it would cost a lot to make, but it would be accurate, and I would know that it would be the best that it could be because I would pay close attention to the way it was designed and manufactured. And paying attention to how parts are manufactured is almost more important than how the part is designed (if you want it to be a good part) Holes have to be drilled exactly where they are planned, and bores need to be straight and accurate. Precision measured in the tens of thousandths of inches needs to be there(.0001). And it's possible, we have the technology, the only thing is that it's not cheap. And there in lies the problem. Not many want to pay over $1500 for an airsoft gun. The only thing I can think of, is to have financing available, like cars. Have the customer pay monthly. But yes, fewer parts is better. Designing the gun isn't the hard part, it's getting it made. Chris R
  10. Tux, Change is very hard to generate. Keeping it real, you need money, which is something that I know that I, and many others don't have. I would be one of the first to step up with a design, and try to make it happen with the machine shops, to get a product, but the fact of the matter is, even if I was able to produce "the accurate gun", they would be expensive, out of the range of all but the most serious airsofters, and I don't think I would break even. And for someone who is in school, and is trying to make rent, that's scary. Just look at Righthook Fabrication. How many guns did they sell? Probably not many. I've only seen two other guys on youtube making videos about them. And they completely cut out their reaper line. Which tells me that business was not good, and that either the product wasn't good enough, or there simply isn't a big enough market for a $1500 airsoft gun up front. I don't know. As for the TM VSR design, I'm split. I think that the one thing good about it is the cylinder, which, fortunately is the area of the gun that is most supported by the aftermarket. However, I must respectfully disagree with you on the matter of the hop up unit. It's just too complicated to be consistent. I do, however agree with you about fixed hop ups. Unfortunately, most people want an adjustable unit. The thing is, an adjustable unit doesn't need to sacrifice repeatability to function. I feel as if I have taken your thread in a way that you didn't intend, and for that I apologize. You were addressing the community rather than the actual mechanics of the equipment, right? PM me tux, I've got some ideas, maybe we can work together on some of this stuff, if you're interested Chris R
  11. The science is important, there is no doubt about that. Understanding the physics behind this stuff is really important, because in reality, the odds are so stacked against the sniper that it's just not even fair. Getting that BB to fly fast, true, far, and most importantly, SAFE, is just so difficult. You can't increase the velocity and weight so much, because if you do, you'll have broken teeth, and penetration to soft tissue, which is something that no one wants. Assaulters have it easy with their equipment. Their troubles come from other issues like reflexes, retention of fine and coarse motor skills, situational awareness, and so on. But their pretty much good to go with the guns. Us on the other hand, it is so hard to maintain a significant range and accuracy advantage over the run-and-gunners with their high volume of fire. I've done the research, and it's sad, but if you ask me, I'd say give up on range. You just can't have a safe airsoft gun that can reach out much past 300'. However, if we really work on accuracy, really just push the issue, and come up with a tack driver, an airsoft gun that can just shoot tiny tiny groups, all day long, with no problem, then your effective range will double. Sure, it'll still be within 300', but you'll be able to hit anyone within that distance. How many times have you been on the field, and you've seen a guy half exposed, and you didn't take the shot because you knew you couldn't hit him. He was in your 300' envelope, but you knew that it just wouldn't happen. Despite the fact that you could put your crosshair on his chest or whatever, it just wasn't possible, because your gun wasn't accurate enough. What if you could shoot one inch groups at 200'? We all play that stupid game with our guns, where we know that the BB isn't going to hit on the point where those two lines in the scope cross. It's going to hit in an area, somewhere maybe close to where you're aiming, so you guess up or down, left or right. Even though you've used your field craft to get yourself into a position to make that hit, well within 200' or 300', it's just not a sure thing. But what if it was? What if you didn't have to put up with that crap? What if you could get within 200', see a guy, sight him, and make the hit, no problem? Oh would that be the day. It's all about accuracy, and it's possible. Making that accurate gun will just be mechanical engineering. Obviously the biggest thing is the ammo. It has to be the RIGHT weight. What that weight is, I don't know. But it's all a balancing act. Yeah, the .88g steel BB will obviously be the most accurate, but it's not safe. .43g might not be safe either. We need to do the research and crunch the numbers to find what weight (and what size) bb will be the best balance between performance and safety. And accuracy isn't the only thing you need to worry about: -How much time the BB takes to get to the target, at various ranges -How much the BB is affected by the environment -How much energy the BB is hitting with at various ranges -MED's See it doesn't matter if it's accurate if it takes so long to get there that the target can move in time to dodge it, or if the wind will blow it away. It's a balancing act. So the first thing to get right is the projectile. Figure out the right size, and the right weight that will get you the most performance, while remaining safe at a reasonable MED, that will get there reasonably fast enough, and will be resilient against the environment to a reasonable degree. And making it is a whole new issue. The BB can't be to hard. It has to be soft enough that it will be safe, but it has to me hard enough to maintain dimensional accuracy throughout the loading process. Figuring out the right material will NOT be easy. The projectile is the hardest part, by far. The gun, however will be easier. Again, it's a give and take balancing act. If you look at the way an airsoft gun is constructed in comparison to a real gun, you will see that airsoft guns really are made cheaply, and are quite flimsy. When you combine the shear number of parts, the two part barrel (inner and outer), the complex hop up, the bad tolerances, and extreme lack of forethought that goes into an airsoft gun, it's no wonder it can't shoot groups. If you look at say, the TM VSR-10 from an engineering standpoint, from a gunsmith's standpoint, you will see that it's crap. Of course, it's a $200 gun, so it's affordable, but then you have guys that will build it up to a $1000 or even $2000 gun. But guess what, it's still a TM-VSR design. If you were to take that lump sum up front, you could build a gun that would have/be: -One piece solid steel barrel, precision gun drilled, reamed, lapped and finished TIR as low as possible -One piece steel reciever TIR as low as possible -Integrated, and SIMPLE hop up unit -Solid bolt -Solid trigger -Bedded into a good stock That would be a heavy, expensive gun. About 15lbs, and $1,000 - $2,000, but guess what, it would be accurate, and durable as hell. It would be the ideal platform to shoot those perfect BB's. Not some flimsy airsoft gun. This gun would basically be made to or above the quality of a real gun. And a lot of guys will diss that. "Why pay that much for an airsoft gun? That's more than a real gun!" And to that, I say: so? So what if it is? It's better to go that way than to buy three or four sub-par guns. I've gone through and I've done the math, to see how much I've spent on airsoft. It's a lot. Upwards of $5000. Mind you, that's over almost 7 years now. I'd rather have spent that on one good gun that 10 bad guns. Now I want to clarify that I respect your guy's gear, okay? I'm not trying to piss anyone off hear, I'm just speaking my mind. A lot of you guys are passionate about your stuff, because you built it up, and I respect that, but it's all built on a bad platform, sorry. It all comes down to money though. No one wants to spend that much, it's just not in the books. Thanks for reading, Chris R
  12. The halo shotguns are unique in that the magazine is on the top of the gun, rather than the bottom, like most modern day shotguns. Do you plan to replicate this?
  13. Sorry to butt in, but what's noobie's website? And I kinda think that all adjustable chambers are crap so... it's kinda like going from something that's bad to something that's less bad. But that's just my opinion. Chris
  14. It's possible, and probably not. There are things you can do to increase consistency though. The hop up was a very good place to start, so I commend you. Chris
  15. Range on airsoft guns is pretty consistent regardless of method of propulsion. The maximum range of a decently accurate sniper rifle in the 500-600 fps range is commonly set at around 250-300 feet, 300 being the absolute max engagement range, and say 350 the absolute max range of the bb. It doesn't matter very much whether it's HPA or spring, that's generally how far the bb goes. Mind you, a lot of tuning and know-how goes into making shots at that range though. It's not all about a nice barrel and some power. Chris
  16. White lithium is more of a load bearing and shear resistant lube. More for gears and sears and such. It all works though. It's not like it's law that you have to use what's recommended. Chris
  17. The Complete Sniper Guide, by The Crimson Falcon This is the complete sniper guide, kindly written by TCF. It's linked to in my sig. Details on lubrication can be found in the maintenance section of this reading. He recommends teflon lube for the outside of the cylinder, silicone lube for the inside of the cylinder, and white lithium for the trigger mech.
  18. There are private matches that employ no fps limit range guns that .80 gram bb's would be perfect for. However, it would be better to just use steel bbs at that point, as the tolerances are phenominal. New ammo options are always exciting :) Chris
  19. It's a 2.5 mm hex head, if that helps. Chris
  20. Sniper flow, I can appreciate your thirst for knowledge, but this information is already available to you. Simply browse some of the 'stickies' in this forum, and your questions will, without a doubt, be answered. (stickies are topics that have greater importance than normal topics, so they appear at the top of the list, so new members, such as yourself, can easily access information that has been deemed important by us, the more experienced members). If you're having difficulties with our 'nerdy lingo', feel free to ask either myself, or another moderator such as Tux or Soldierbane about them via the PM system. (PM stands for personal message. You can send me a PM by clicking on my name, and selecting the option 'send message' on the drop down menu) I'm going to close this thread, as this very question has been asked perhaps hundreds of previous times. If you're unsatisfied with the answers you've received, please PM me, and I'll link you to a few threads that already have the answers you desire. Have a good day, Chris
  21. Chill everyone. If you've got something to say, say it nicely. He doesn't need encouragement, snipershot. Chris
  22. I agree with tux, but to a point, it's good to watch who you shoot. It's probably a bad idea to take out the Newbies, as they aren't much of a threat, and you're just exposing your position to take out a non-threat. Airsoft generally isn't as structured as how you outlined. Everything is relatively the same. The differences between mp5's, m16's, and machine guns in airsoft in terms of threat level are very minimal. It's just how the game works. In my mind, there are Newbies, good players, really good players, bad snipers, and good snipers. It's more about the person using the gun than the gun itself. The gun shoots bb's, that's all it does, and at most fields, most everyone shoots at the limit accept for the Newbies, so everyone's gun is pretty much the same in terms of performance. I suppose if I were to make a list of people to kill first.. it would be like this: good snipers - really good players good players Newbies bad snipers But really, if you have the chance to take someone out of the game, you might as well take it. It's foolish to 'look' for 'VIPs', or 'high value targets'. Unless, of course, you are playing an objective game. But don't blow your cover to frag a Newbie, you know? It's just not worth it. He's probably not going to be much of a threat. But if you can take him out without compromising yourself, hey, what the hell, why not, right? Chris
  23. That's not the point he's trying to convey. Also, please try not to double post. Thanks, Chris
