ASA operate muzzle velocity limits based on the energy in joules to allow players to use higher weight BBs without compromising safety. We also adhere to ASNZ guidelines for velocity limits. Below is a chart showing the correlation between the BB weight, FPS (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.

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

The DS, Committee, and or Event Organiser has discretion to re-test any gun in possession of a player on field, to ensure the gun remains within these limits.
This is important for operators of gas blowback guns, due to the inconsistencies of the gas especially during warmer days, which may result in a higher reading than the initial pre-game test and ultimately leading to the gun being banned at any time of the day.

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 measured with 0.2g BBs, as well as Joules.

ASA operates three classes of weapons:

CQB Class

Max of 1.13 J (350 FPS 0.20g)
No minimum engagement distance.

Assault Class

Max of 1.63 J (420 FPS 0.20g)
Minimum engagement distance: 10 meters

Sniper Class

Max of 3.33 J (600 FPS 0.20g)
Minimum engagement distance: 20 meters

For all Sniper Class are further subjected to the following conditions of use:

• Must be a bolt-action style gun with no full-automatic or semi-automatic capabilities.
• No sniper class gun can be used at induction games by anyone.
• Working CQB rated secondary must be carried and used within 20m ranges.
• Use of these will cause the authorized user to be under constant scrutiny. Use remains at the committee/DS discretion.
• The committee reserves the right to retroactively disallow any weapon.
• Must be a member in good standing (Committee discretion), having been playing with ASA for 12+ months.
• Engagement distance is 20 meters for anything over 420 FPS measure with 0.2g BBs.
