A brief history and description of airsoft

Airsoft originated in Japan, then spread to Hong Kong and Japan in the late 1970s. Airsoft guns spread to the UK in the 1980s with a company called LS. The guns were sold in pieces and had to be assembled before they were capable of firing pellets. I bought my first Airsoft gun in 1984, an LS Colt 1911. I modified it of course and managed to increase the fps from 180 to 270, the gun didnt last long but i learned some lessons, and have been doing so ever since. Airsoft guns have progressed massively since the mid eighties both in terms of technology, and materiels used in their construction, they have also progressed from the purly recreational to the professional training weapons we see on sale and in use today.

Airsoft guns are classified according to their operating principle, which can be spring loaded, electric ( Automatic Electric Guns, "AEG's"), or gas-powered (some are blowback, "GBB", and some are non blowback, or "NBB", Blow back describes the action of the slide being blown backwards by the release of propellent gas into the chamber to fire a "BB").

The "Hop-Up" system, which is installed in most airsoft rifles and pistols, is used to add extra range by putting backspin on the pellets, causing them to rise upward as they are fired. A small rubber nub protrudes into the top of the barrel through a small hole, and it catches the top of the pellet as it flies past. Adjusting the Hop-Up makes the nub protrude lower or higher into the barrel, so that backspin is increased or reduced. Ideally, the Hop-Up should be adjusted so that the pellets fly as far as possible in a straight line without curving upward too far, or dropping to the ground too quickly.

Most airsoft guns fire round plastic pellets, usually white, but black "invisible" or phosphorestic are common as well. The pellets mostly range from 0. 12 to 0. 48 g. However, the most popular weights for AEGs (automatic electric guns) and GBB* (Gas Blow-Back guns) are 0. 20 g and 0. 25 g.

Heavier rounds (0. 30–0. 43 g) are typically used in long range and sniper applications since they are more stable in flight and less easily deflected by wind. Pellets are typically 6 mm in diameter, though 8 mm pellets do exist.
