At this moment, he noticed that besides the blue pattern on the gun body, there was a special blue arrow mark, accompanied by the English words "Blue Arrow-Arrow15".
This should be a custom version of the AR by some firearm company.
The AR-15 was the first rifle to use a 5.56 mm caliber, thus it is also hailed as the pioneer of small caliber rifles. The US military's M16 is a modified version of it, while the civilian version has removed the selector switch, leaving only a semi-automatic single-shot mode.
Due to the excellent performance of the AR-15, after its patent expired, firearm factories around the world began to replicate it, so various custom versions are not unusual.

Why does the security of a tech company's research center need to be equipped with assault rifles, and why do they start shooting indiscriminately, not giving any chance for explanation?
Shooting to kill just for breaking into a research center?
