AR-15步枪在室内靶场进行慢动作射击

er fires an AR-15 style rifle inside an indoor shooting range. The image captures the precise moment of ejection, with a brass cartridge case visible in mid-air next to the firearm. The shooter is holding the rifle with a firm grip, aiming downrange at a cardboard target. The rifle is equipped with a mounted optic (SIG Sauer red dot sight), rail system, and standard AR-15 controls. The blurred background emphasizes the motion, while the sharp detail of the brass case freeze-frames the firing sequence.
