Given that present-day specialist snipers already use special-purpose palm-held ballistic computers to further improve their already exceptional performance, can such computers be designed specifically for Airsoft use?
By: Ringo Bones
It seems like only yesterday – actually back in those few years preceding World War II – that ballistic computers of sufficient accuracy were mechanical devices the size of a spacious room. Like Dr. Vannevar Bush’s Differential Analyzer of the 1930s which was later used to calculate artillery trajectories during World War II. Surprisingly, a much smaller – though the accuracy is scaled-down as well – ballistic computer portable enough to be held in one’s hand was invented by a French artillery officer named Amédée Mannheim called the slide rule back in 1850.
These days, specialist snipers are more than likely to use those palm-held Blackberry-sized / Blackberry-looking special purpose battery-powered electronic ballistic computers, like the KAC Bullet Flight 2.0.0 by Knight’s Armament Company, described as a ballistic computer designed to provide quick firing solutions in the field; Palm-held push-button firing solution, anyone?
Similar and / or related devices appear as if they are now fast becoming an indispensable part of the specialist sniper, almost as indispensable as the sniper’s weapons system. Though I haven’t seen a present-day sniper resorting to use a 1950s era slide rule to compute his or her firing solution just to make a statement on how battery-operated devices had dumbed-down the world. And there’s even probably a ballistic computer i-Phone-style app being offered somewhere already. But can such devices be of used in the world of Airsoft gaming?
The problem with Airsoft weapons systems justifying the necessity of ballistic computers is that the 6-mm plastic pellets themselves – Airsoft ammunition – have a non-existent ballistic coefficient. I mean they are spherical and light, unlike a high-performance rifle bullet that’s conical, of sufficient mass and spin-stabilized in flight. In short, spherical 6-mm BB pellets for Airsoft use are a far cry from a 123-grain Lapua Scenar round with a ballistic coefficient of 0.547 and a muzzle velocity of 2,600 feet-per-second famed for its ability to hit tennis-ball-sized targets at 600 yards or 1,800 feet away.
No matter how much you tweak your Airsoft weapons system to give you an initial muzzle velocity approaching 600 feet-per-second, the spherical BB pellet’s very lousy ballistic coefficient will always preclude your Airsoft gun from hitting a tennis-ball-sized target from even as close as 94 feet away – the full length of a basketball court. Real life should have been much easier for the Airsoft gamer, but it isn’t.
Computing the ballistic coefficient – if it ever has one - of a spherical 6-mm BB pellets made of mineral-reinforced polypropylene weighing 0.2-grams or slightly heavier will probably require the computing power of a 1995-era Cray supercomputer or better. Airsoft manufacturing firms probably don’t have the R & D time and money for such an endeavour. Even using a 1950s era slide rule to compute a firing solution during a typical Airsoft game is probably as effective as being able to see the planet Uranus using a 3X sniper scope.

Mpingo Goes Airsoft
Better known in the hi-fi world as a widget for controlling unwanted vibrations, does Mpingo have something good to offer to the world of Airsoft?
By: Ringo Bones
Unlike most Airsoft clubs that I’ve been involved before, my current one seems to have a fascination with Airsoft replica guns that have wood in them. Having never acquired the taste for black impact-resistant polystyrene that every other Airsoft enthusiast seems to fetishize, I find my current teammates’ obsession with real wood veneer on their Airsoft weapons systems somewhat refreshing. Real wood veneer does look good on a PPSh brass fountain sub-machinegun, an M-1 Carbine or those Kalashnikov-like Soviet era infantry weapons. One of my teammates even made the butt-stock of her Kalashnikov look like that of the futuristic ray gun toted by Jane Fonda’s character in Barbarella. Remember that ray gun with a curvy Art Nouveau inspired rifle stock from the iconic 1968 film classic? Given the amount of wood in these types of Airsoft model replica guns, would the use of Mpingo in strategic places improve their handling?
It has been a well-known fact for sometime now that up-market Airsoft guns tend to be more comfortable to hold on to when fired in long continuous bursts than their counterparts at the lower end of the market. Could it be that they have better vibration isolation systems? Recently, a group of hi-fi enthusiasts who are also into Airsoft have wondered whether Mpingo’s ability to absorb unwanted resonance would be an asset in designing a better Airsoft weapons system. Mpingo is a dense African swamp-ebony hardwood used by hi-fi widget manufacturer Shun Mook as a way to absorb unnecessary resonance and vibrations that can degrade a hi-fi system’s sound quality. Given that Airsoft guns’ propensity to vibrate somewhat violently when fired at long continuous bursts, will strategically placed pieces of Mpingo improve handling qualities?
The concept of using strategically placed Mpingo pieces in an Airsoft weapons system to damp out unwanted vibrations is a very intriguing concept indeed. Given that Airsoft guns are already expensive, the use of Mpingo – which unfortunately has a fecundity rate like that of a great white shark – will probably add a very steep price premium. Probably a good way for those with money to burn to experiment that is if you can handle the guffaws for not being so environmentally friendly. Please tell us if the improvement in handling is worth the additional expense.

Militia Groups: Still A Valid National Security Paradigm?
Given the relative military success of armed militia and partisan groups during the Balkan civil war and the 2003 invasion of Iraq are militia groups still a valid national security paradigm?
By: Ringo Bones
For a number of years now, several lawmakers across the world have deemed Airsoft clubs as nothing more than a training ground for “unregulated militias”, and yet militia groups have lately been praised as the last line of defense against imperialism. With the relatively successful resistance posed by militia groups acting in a partisan capacity form a military standpoint during the turbulent Balkan region civil war of the 1990s and the ill-advised invasion of Iraq by the Bush Administration back in 2003. It could be said that as long as an invading imperialist armed with the latest state-of-the-art weaponry like stealth bombers and the H-bomb still adheres to the Geneva Convention and related rules of war. The invading imperialists seem to be powerless when facing against modestly equipped ragtag militia groups acting in a partisan capacity. But is there any truth to this?
There has been a “silent revolution” moving across the world – especially citizens of relatively stable democracies – for their respective lawmakers to grand them gun owning privileges modeled after the American Second Amendment as a deterrent against their country accidentally electing a tyrannical leader or an invading army. Since the end of the Cold War, it seems that fiscal austerity became the norm when it comes to national defense spending of most relatively stable democracies during much of the 1990s. But the 9/11 attacks changed all that and the very same countries now face the problem of bolstering their national defense as fast as possible while spending as little as reasonably possible.
This is where the citizen-militia comes in. Private gun owners – especially those who own infantry style assault weapons that are more often than not of higher quality and better maintained than those issued in their respective national armies – can act in a sort of partisan capacity. Harassing the invading enemy until the invaders eventually get sick and tired of it and give up to go home. Given the recent events documenting the relative success of such scenarios, one can easily conclude that private assault rifle owners – in particular – could be truly a typical country’s last line of defense. This is where Airsoft clubs could serve its usefulness as a training ground for basic firearms safety and first-hand exposure to military-style operations to the civilian gun enthusiast.

Are Airsoft Clubs Virtual Militias?
The hardware may just be well-crafted simulacra of real infantry small arms, but does your typical Airsoft club qualify as a true-blue militia group?
By: Ringo Bones
Traditionally, militias have always been accepted as a part of the organized armed forces of a typical country liable to call only in emergency. Some would say the whole body of able-bodied male citizens declared by law as being subject to call to military service. But ever since the fall of the Berlin Wall that eventually lead to the end of the Cold War, militias anywhere in the world are more often than not established by disaffected young men and women coming together for collective security. Primarily due to the fact that these young men and women’s respective government have found it very politically expedient to infringe upon their collective allegiances and / or lawfully acquired material possessions and titles just for the reasons of belonging to an ethnic minority.
Worse still, the Bush Administration’s badly-run War on Terror in which the Obama Administration unfortunately inherited had supposedly implied to every not-so-democratic regimes around the world loyal to the United States to enact their own “carte blanche” when it comes to tackling “terror groups”. Thus making these not-so-democratic regimes team up with their very influential clergy to freely preach sanctimonious religious rhetoric on wealth redistribution aimed at a wealthy ethnic minority as a way for these regimes to shield themselves from anti-corruption whistle-blowers – when there’s a scapegoat, there’s a getaway perhaps?
Given that the United States is the only developed nation that allows its citizens the right to keep and bear arms via the Second Amendment of the US Constitution about not infringing on the establishment of a well-regulated militia. It seems quite odd that there are some states in the US where establishing of Airsoft clubs is deemed illegal. Some countries too that are loyal to the US and her interests have deemed it illegal to have Airsoft clubs. While some of them have legalized paintball clubs, these paintball clubs are not allowed to give advanced tactical training – like CQB, hostage rescue of astronauts landing in hostile zones and room clearing - to their civilian players.
Even though they are just over-glorified versions of pellet guns, there is one thing that you can do with an Airsoft weapons system that you can’t do with a modern infantry-style assault rifle. That is to shoot your opponent without killing him or her or involving lengthy hospital stay during one of your simulated war games. As firm believers of the Second Amendment is just an extension of the First Amendment, all of my Airsoft teammates have real guns – an average of three in fact (infantry style assault rifle, main sidearm and a concealable small backup handgun, while some own man-portable anti-tank and anti-aircraft weapons systems, etc.) – all unregistered and deemed necessary due to their very healthy mistrust of the government that considers ethnic minorities prettier looking than them as vermin. Sometimes I even wonder if these elected officials have ever heard the concept of the Posse Comitaus Act or the US Constitution’s Second Amendment.

Blood, Sweat, and Airsoft
It always makes perfect sense to seek out bargains, but is your typical low-cost Airsoft gear ethically produced?
By: Ringo Bones
Maybe it was that BBC produced documentary titled Blood, Sweat & T-shirts exploring whether typical high street fashion items are ethically produced that had me to start wondering if your typical low-cost Airsoft gear passes muster as being ethically produced? But first, let us examine the idea about what makes a typical product and / or commodity ethically produced.
Ethically produced products and / or commodities are usually defined by the way the workers responsible for producing and making these items “marketable” are compensated fairly and / or ethically for their laborious efforts. Some companies are starting to advertise that their goods and services are ethically produced, although they are still part of a very tiny minority that announce to the world that they practice ethical business governance.
In the world of hi-fi, Wilson Audio Specialties can be considered a paragon when it comes to championing ethically produced products. Dave Wilson and his wife, Sheryl Lee, always made sure that everyone interested in acquiring their renowned loudspeakers knew – either through advertising and plant tours – that their factory workers are provided with full healthcare coverage and matching 401K plans. Wilson always made sure that when a customer buys one of their 45,000 US dollar per pair loudspeaker that’s made in America and built in-house, the customer is also paying for their workers’ way-higher-than-Wall-Mart-wages and benefits that his company are his obligation to his loyal team.
But in the Airsoft gaming world, every time you look at their glossy catalogues of Airsoft weapons systems, BDUs, and other replica of infantry-level paraphernalia. The testimonials and assurances – that are verifiable via plant tours and Michael Moore-style fact-finding missions - to whether their products are ethically produced are nowhere to be found. If you are following on the Beeb on the incidences of forced labor camps of the People’s Republic of China, it can be somewhat disconcerting to think about it every time you buy those ultra-cheap Airsoft weapons systems and their associated peripherals. Especially if they are made in the People’s Republic of China.
Given that most of us are starting Airsoft clubs as a way to save money in firing real ammunition and / or able to use low-cost non-lethal weapons systems on each other. No, make that because the primary goal of our rag-tag militia is to stop tyranny when our own government’s military can’t or won’t be bothered to do so. The ideals we are fighting for should extent to the ones making our goals possible. Airsoft gear providers should start making sure that their products are ethically produced because their regular customers can always boycott their products. If you bought that Free Tibet concert DVD, maybe you should start concerning whether your Airsoft gear passes muster as one of those ethically produced products.

Should Helium Be Used In Airsoft Gas Blowback Guns?
Given that the laws of thermodynamics dictates that gases of low molecular weight have excellent work function, should Airsoft gas blowback guns use helium instead of Green Gas?
By: Vanessa Uy
It is well known in the Airsoft gaming community that gas blowback guns – especially handgun replica weapons systems – uses refrigerant like gases, like Green Gas and Red Gas as the working substance for these type of guns. But shouldn’t gases with low molecular weight like helium or hydrogen make better gases for use in gas blowback Airsoft weapons systems? After all, our current understanding of the laws of thermodynamics states that gases with very low molecular weights have a very excellent work function when used as the working substance in a typical mechanical system.
Though it never got used as a battlefield weapons system due to it’s relative complexity, the light-gas gun system is a good example of how a working substance of low molecular weight can produce very excellent performance – in projectile velocity terms – when used as a gun propellant. Oddly enough, the mechanical principle of the light-gas gun system is akin to that of a typical Airsoft AEG weapons systems’ piston, cylinder, catcher section, and launch tube set-up.
Operation of the light-gas gun system consists of igniting a conventional powder propellant in the propellant chamber, which forces the pump piston down the pump tube, compressing the helium or hydrogen gas – usually pressurized at 450 to 1200 pounds per square inch before firing the propellant. This gas eventually builds up sufficient pressure to cause the diaphragm to burst. It is the release of this pressure that propels the projectile from the launch tube. The catcher section of the gun serves to limit the forward motion of the pump piston.
Projectile velocities of the light-gas gun system are of the order of 7,000 to 15,000 feet per second, while conventional battlefield guns – like howitzers – are limited to 7,000 feet per second. Although the 7,000 feet per second figure is the sole domain of artillery pieces that fire tungsten carbide or depleted uranium cored disintegrating sabot projectiles, those that fire your typical high-explosive fragmentation projectiles are probably limited to under 5,000 feet per second in their muzzle velocities.
The higher level of performance attained with the light-gas gun system is attributable to the low molecular weight and the correspondingly high sound velocity of the working substance acting on the base of the projectile. These guns are typically used in research labs that investigate the hypervelocity impact damage of meteorites or space debris on satellites and manned spacecraft.
Given that hydrogen has the inherent hazard of flammability and the long term ozone layer and global warming hazards of Green Gas and Red Gas – i.e. HFC-134a and HCFC-22 – are yet to be determined. Even though one cannot directly substitute helium for Green Gas or Red Gas because your typical Airsoft gas blowback mechanical systems are pre-designed to work only with either Green Gas or Red Gas. It looks as if the use of helium as a working substance for Airsoft gas blowback guns has been unfairly overlooked.
Although Green Gas and Red Gas are now readily available in Airsoft shops throughout Southeast Asia, helium tanks typically sold to fill party balloons are more widely available. Also, helium has a greater commercial and industrial incumbency than either Green Gas - a mixture of propane, polysiloxane lubricant and HFC-134a refrigerant – or Red Gas – a mixture of carbon dioxide, nitrogen and the refrigerant HCFC-22. Because it has been sold for a while longer than either pre-packaged Airsoft working substances, plus the laws of thermodynamics proves that helium is a more efficient gas than either Green Gas or Red Gas - mystery of mysteries indeed.
