The guns featured in the sites and links are all model guns. They are replicas of real guns. To the untrained eye, there is no difference.
Air Soft has been in the Philippines since 1985 and is a very good indoor/outdoor sport. If it rains, the fun begins. If its hot and sunny, oh well, at least there wont be pressure problems.
AEG stands for Automatic Electric Guns. As far as I know, gas powered SMGs and rifles are now banned in all private and public playing fields due to the uncontrollable nature of their power. The only gas powered allowed are 134A and Green Gas (compressed air) pistols. The highest muzzle velocity allowed by a sanctioned group here in the Philippines is 450feet per sec or 150meters per sec using a 0.3 gram 6mm airsoft BB. I know that it is significantly much lower elswhere allowed (ie, Canada, US of which up to 420 fps is allowed on some fields and lower on others using a 0.25gram airsoft BB).
Now think of how painful it will be to get hit at approximately 150 ft with a 0.25 gram bb at 440 fps. If you smile :D and get hit at your tooth, you'll be visiting the dentist, so not only is an eye wear mandatory, a full face and neck protection is advised as well.
I used to own a gas powered (380 fps at 0.25gram) semi and full automatic machine pistol (Beretta AUTO9). For a pistol... this one packs an extremely strong punch (usual fps by pistols is only up to 280 at full modification during the time). The pistol was personally moded by me using both specialized upgrade kits and some fabricated parts (such as springs and valve pins). It is powered by a compressed air gas tank with a 3 stage booster piggy backed on the tank. Typically, it would power larger equipment like assault rifles and smgs but in my case... well... I'm pistol whippin opponents (ROBOCOP style).
Air soft is in some ways better than paint-ball. The most you'll spend for a pain ball rig with outfit would roughly run you down Au$8,0000. For the same amount of money, the sport of Air Soft would give you a choice of a Sniper Rifle (like the M24 SOCOM-bolt action gas powered) or an assault rifle (like an AK 47, M16A2, SR16/15, AUG!!!, H&K G3/A3,FAMAS)and an electric SMG (like an MP5 SD6 or SD5 or an FN P90) plus, you get a pistol as 3rd weapon for sidearm. Now thats not all. All of them will be moded (I like modding :mrgreen:) to perform to optimum field standards (mods like barrels, pistons, springs, motors, batteries, feed mechanism and even reciever groups and other accessories like scope and sights) so that your equipment will be within tolerable limits of the playing field.
There's a bit of danger to society when bad people mishandle airsoft. There have been numerous incidents where air soft replicas has been used to orchestrate a robbery and people could pose as illegal military personel weilding "high power weapons" made of ABS plastic.
I departed from the airsoft scene a long time ago as the heat was getting too hot for airsoft. I heard rumors that it has been banned already here due to the criminal incidents associated with it but then, the merit of sports and recreation by responsible people probably has given it another go.
That's a bit of my side on this... hope I didn't bother ya too long :P
If you do dive into this... don't go RAMBO... :D
