M16
From WikiRaider
The M16 is a long range assault rifle which is found in Tomb Raider II in the level Diving Area. It has a similar effectiveness as the Uzis but is quite useless when the opponent is close by, as Lara will need space and time to aim the weapon. It can not be fired while jumping around.
The MP5 in Tomb Raider III is a similar weapon.
