The Remington ACR (Adaptive Combat Rifle), previously known as the Magpul Masada before Remington took over production, is an assault rifle developed initially and proposed for the future replacement of the venerable M16 family of assault rifles. The ACR uses the standard 5.56x45mm NATO round but is also intended to be modifiable to employ the 6.5 Grendel, 6.8mm Remington SPC and the Russian 7.62x39mm M43 rounds.
