A255

The A255 is a powerful radio weapon. It creates sounds via distortion and 10 Volume, so that their sounds outputted are so loud it can destroy Robloxian's eardrums and cause brain damage. However, the brain damage is not as extreme as the weapon's successor, the A255X. The weapon is illegal during peacetime in many Robloxian states and Moon Base Blox as of 2021 because it was used to play inappropriate audios and also was found to be a cause of immaturity and annoyance in the Robloxian populace. Because of its illicit nature, A255s were reported to be smuggled into illicit states and bases.

*Assuming the weapon is fired at a diatomic gas medium ( adiabatic index 1.4 ) with density 1.225 g/m³ at a pressure of 1 atmosphere. Artillery speeds may vary depending on the medium's adiabatic index, pressure, and density. The artillery speed of any assault radio rifle regardless of the medium can be calculated using this mathematical equation: ${\displaystyle v_{s}=\sqrt{\frac{\gamma P}{\rho}}}$, where ${\displaystyle \gamma}$is the adiabatic index of medium, P is the pressure of the medium, and ${\displaystyle \rho}$is the density of the medium.
