Airsoft Glossary of Terms

 

Airsoft is a growing sport that men and women worldwide participate in for various reasons, whether for firearms training or for hobby. However, even long-time players may not know all the airsoft vocabulary that the industry uses. For example, you may be aware of AEG and AEP, but do you know the differences between the two? Or what about LPEG?

Whether you’re new to airsoft or you’ve been playing for years, there may be some airsoft terms you’ve heard of but don’t quite understand. For a full list of airsoft terminology, review the terms and definitions below.

Hi-Capacity or High Cap

Also referred to as High-Cap or High-Caps, these terms are used to describe manually or electrically-controlled airsoft magazines containing between 300 to 5,000 pellets. In airsoft, larger capacities are always an advantage, making these magazines the most commonly used magazines in airsoft play. However, high-cap magazines are not permitted in many competitive airsoft events.

Honor System

Honor System is an ethical conduct standard used by airsoft gamers. When a player is hit, he voluntarily acknowledges that he has been hit and removes himself from the battle.

Hop-Up System

Also referred to as Hop-Up, this term refers to the backspin created on a projectile by the rifling used in the barrels of actual firearms. This adjustable mechanical system causes BBs to pass through the Hop-Up and spin backwards, which extends the range of the BBs flight. This allows the shooter to engage targets at further distances.

(I)

ICS

ICS refers to I Chih Shivan Enterprise Co., a reputable airsoft manufacturer.

Imitation Firearm (IF)

In the U.K., Imitation Firearms are two-toned devices which can be purchased by individuals over 18.

Low Capacity Magazine (Low-Cap)

Low Capacity Magazines contain less than 100 rounds, making them more realistic to real guns. They are often used in competitive airsoft tournaments.

Magazine

Magazine refers to a fixed or removable compartment that holds a volume of ammunition to be fed into the firing device.

Mainspring

Mainspring is a coiled spring compressed to power the internal piston of a Springer or AEG device.

Mechbox

Mechbox is the heart of an AEG device. Using electrically-powered spurred airsoft gear, the Mechbox compresses and releases the mainspring that powers the piston. This results in creating the compression chamber PSI which is needed to send the BB down the barrel, aimed at the target.

Mid Capacity Magazines (Mid-Cap Mags)

Also referred to as Mid-Cap, these magazines contain more rounds than low capacity magazines but less rounds than higher capacity magazines. Mid-Cap Mags contain between 100 to 200 rounds. They are often quieter than higher capacity magazines.

Military Simulation (MilSim)

Some airsoft players engage in a military-themed role playing setting, referred to as MilSim. Teams generally remain on the field until their objective has been reached or until they reach their time limit.

Mid Powered Electric Guns (MPEG)
