Armalite AR-10(T)

The Armalite AR-10 Special is a 7.62 mm, semi-automatic battle rifle. This gun is owned by Rika Minami and she has illegally modified it in the style of a Knight's SR-25, giving it a fully automatic function. The AR-10n is primarily used by Kohta Hirano and has been called his favorite gun.

Overview
The AR-10 is produced by Armalite and was the original design of the AR-15 (M16). It has a rotating lock as most NATO weapons have, is air cooled, and magazine fed. It primarily uses 20 round magazines.

Plot
Kohta finds the AR-10 in Rika's household. He instantly gets attached to it and uses it numerous times. However, he is seen to actually replace it sometimes, as he is seen using an MP5SFK before giving it to Saya.
