Airsoft Terms & Definitions

AEG - Automatic Electric Gun. A rifle or machine gun that compresses and releases its own air by using electricity to power a series of mechanical actions inside a "gearbox".

AEP - Automatic Electric Pistol. A pistol that compresses and releases its own air by using electricity to power a series of mechanical actions inside a "gearbox".
BB - The projectile which an Airsoft gun fires; a sphere usually consisting of plastic and measuring 6mm-8mm.

DMR: Designated Marksman Rifle. This refers to AEG's that have been upgraded internally for greater power, range, and accuracy.

FPS - Feet Per Second. A measurement used to determine the velocity of a bb when it exits the muzzle of the gun.

GBB - Gas Blow-Back. Refers to a weapon which uses gas to propel a bb and uses a portion of the gas to drive back a slide or bolt to model the realistic function of a real weapon.

GEARBOX - The part of an airsoft gun which houses the components used to propel bbs from the weapon. Click here for an animated diagram.

High-Cap - High Capacity. Refers to the storage capacity of a magazine, usually one that holds 200-5000 bbs.

HOP-UP - The part of an airsoft gun which controls the vertical trajectory of a bb. Click here to see diagram (Scroll down until you come to the first diagram.)

Inner Barrel - the long cylindrical tube or pipe through which a bb passes before exiting the gun. 

Low-Cap - Low Capacity. Refers to the storage capacity of a magazine, usually one that holds less than 100 rounds.


LPEG - Low Priced Electric Gun. These are the type of guns you'll find at Walmart, Dick's Sporting Goods and other hobby/sporting good stores. In addition to their cheap plastic externals, these guns have plastic internals which are not nearly as durable as the metal internals found in mid to high quality guns. LPEG's also have a low FPS and little to none upgrading capability.

Mag - Abbreviation for magazine, the part of an airsoft gun which houses and feeds the bbs into the weapon.  

MPEG stands for Mid Priced Electric Guns. Most of these guns have metal gearboxes and are cloned off of Tokyo Marui's designs. Companies such as JG and CYMA have really come along in the MPEG category, providing durable, quality weapons at a low cost.

Mid-Cap - Mid Capacity. Refers to the storage capacity of a magazine, usually one that holds 110-175 bbs.

NBB- Non Blow-Black. A weapon which uses gas to propel a bb but does not drive back a bolt or slide.

ROF - Rate Of Fire. How many bbs an Airsoft gun can propel in a given period, usually in rounds per minute.

RPM - Rounds Per Minute. How many bbs are expelled from an Airsoft weapon within one minute.

RPS - Rounds Per Second. How many bbs are expelled from an Airsoft weapon in one second.

Tightbore Barrel - The inner barrel of an airsoft weapon with an inside diameter of 6.01mm-6.05mm.
