The first of its kind, and the only rifle you need to master the infinite number of extreme scenarios you'll face in the worlds of law enforcement and personal defense. Our new Bushmaster ACR redefines the term "modular" with the extraordinary ability to change calibers, barrel lengths and stock configurations in minutes – without the use of tools. Truly the most versatile and adaptive rifle ever conceived, it was born of a collaborative effort between Bushmaster, Magpul® and Remington® to create the ultimate military combat weapons system. We're proud to unveil the evolution you see here – built specifically for our law-enforcement and commercial markets. It's tested and proven reliable in the most brutal conditions on earth, truly ambidextrous and the uncompromising choice when you demand a rifle as mission-adaptable as you are. The Bushmaster ACR.
