The Guns of Den of Thieves
The guns of Den of Thieves (2018) — Big Nick O'Brien's RMR-cut M&P, red-dot FNX-45, and FN SCAR; Merrimen's ex-military crew with their HK416, SIG, drum-fed Saiga, and the M249 — each real gun mapped to a current production model you can build, with the optic where it's documented. One of the most gun-literate heist films ever made. Researched from public sources; not affiliated with the film.
The heist movie the gun world reveres — an elite crew, a relentless sheriff, and meticulously real kit.
