About the LR-300 Assault Rifle
A full reload takes 4 seconds, and switching to it takes 1.5 seconds. It can switch between burst fire and fully automatic fire. Aiming down the sights narrows its spread from 3.2° to 0.2°, 16 times tighter than firing from the hip. Its 13 compatible attachments include a silencer. Mounted in an Auto Turret, it deals 35% of its normal damage.
There are 4 kinds of ammo for it: 5.56 Rifle Ammo, Explosive 5.56 Rifle Ammo, Incendiary 5.56 Rifle Ammo and HV 5.56 Rifle Ammo. With the other ammo types, its damage per second is 180 for the Incendiary 5.56 Rifle Ammo and 160 for the HV 5.56 Rifle Ammo. The HV 5.56 Rifle Ammo flies fastest, at 675 m/s, and the Explosive 5.56 Rifle Ammo and Incendiary 5.56 Rifle Ammo slowest, at 338 m/s.
From full condition it fires 600 shots with the 5.56 Rifle Ammo before it breaks, which is 20 full magazines. With the Explosive 5.56 Rifle Ammo, which wears the barrel harder, that drops to 200.
