This version has a 30 round magazine - 5.56x45mmFile:Fastfive-M16-1.jpgIf you look closely, you can see the slab-sided receiver that distinguishes the rifle as a M16/SP1. Another interesting thing to note is that in this scene in the trailer, it seems sound editing has given the M16/SP1 the profile of a automatic M60.
M14
Agent Wilkes (Fernando Chien) is armed with what appears to be a short-barreled version of the M14 with a scope, bipod and AN/PEQ-15 IR designator.
A GE M134 Minigun with a shortened barrel is fired by one of Reyes' men as he chases Toretto and O'Connor in the finale. The sound effect of it firing makes it sound like generic "machine gun fire" than an actual minigun.
