ASA operate muzzle velocity limits based on the energy in joules to allow players to use higher weight BBs without compromising safety. Below is a chart showing the correlation between the BB weight, feet per second muzzle velocity and the resulting energy. The shaded areas illustrate the limits of each class of airsoft gun determined by the BB's energy. The lighter area above each shaded block is the leeway given to compensate for gas pressures and inconsistencies in SEGs.

We ask players to avoid going right to the maximum limit as this may result in a chrono being taken on the day and the gun being banned. Any gun above the following limits will not be allowed on the field. No exceptions, even if its over 1 fps. It is the owners responsibility to ensure all their guns are well within the permitted FPS. These rules are in place for the safety and enjoyment of all players at ASA events which ASA take very seriously. For ease of understanding the following limits are given in FPS as well as Joules (assuming the user has 0.2g BBs loaded). ASA operates two types of games (CQB and Outdoor) and depending on the site used, the appropriate FPS limits will be in effect.

CQB (close quarter battle and indoor) games

CQB Limit of 1.01 J[/b] (330 FPS) Max of 1.13 J (350 FPS)

Outdoor games (2 classes of guns)

Assault Limit of 1.71 J[/b] (430 FPS) Max of 1.87 J (450 FPS) (Be careful of engagement distance and ideally have a back up pistol within CQB limits)

Sniper

Limit of 2.6 J (530 FPS) Max of 2.8 J (550 FPS) This will NOT be your first gun at your first game. True sniper rifle, bolt action, with scope and low cap. A backup pistol or SEG below 350 fps is required. For players with 1 year gaming experience, a SEG sniper may be allowed, although committee and DS approval will be required. Those seeking to use sniper class guns must contact the ASA committee and have their gun registered. Guns will be tested at both indoor and outdoor games. Guns in breach will not be allowed on the field. Furthermore at any point, a DS or committee member can test or ban the use of a gun on the field if it is being used in an irresponsible manner.
