The A-300 blaster rifle was a blaster rifle manufactured by BlasTech Industries, similar in appearance to the A280 blaster rifle and almost identical to the A280-CFE. It was notably used by many Alliance Special Forces members of Rogue One during the Battle of Scarif .
The A-300 contained a power cell housing and an adjustable electroscope. The weapon had several variant configurations. The compact version of the A-300 had a collapsed barrel and removed shoulder stock. A rifle configuration contained an extended barrel and shoulder stock. It could also be configured into a sniper rifle by replacing the barrel with an air-cooling barrel shroud, which looks very similar to the A310 rifle.
