Pain & Gain (2013)

Factual error: The movie is set around 1995. But the SWAT team in the movie is wearing gear from the 2000s. (MICH-2000 helmet, modular tactical vest, M4 variant with picatinny rails and scope). Plus, in a scene when the guys are shopping for a taser (gun shop scene), some of the rifles on display are from 2000s era. AR-15 variants with variant stock, foregrip and picatinny rail. Those style of weapon system were unheard of in early 90s. Even Special Forces just adopted it by the late 90s.

Daniel Lugo: My name is Daniel Lugo, and I believe in fitness. All this began because it was time to push myself harder, otherwise I was looking at another forty years wearing sweatpants to work.
