Ruger 5.56mm Assault Rifle Rounds

During the attack on Frank's house a lot of 'spent' rounds are seen falling to the ground. The extended tip and star crimped ends indicate that they are 5.56mm blank ammo sheels. The rounds appear to be falling from an M16 rifle but during the close up shots of the shells hitting the ground it is clear that they are Ruger AC556 Carbine - 5.56x45mm shells. Scene filmed in Cassis, France.
