16.5" Cold Hammer-Forged Barrel
Gas-Pistol Operating System
Fully Ambidextrous Controls
Bullet Button Lower Receiver
The 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. A quick-change barrel system teams with a multi-caliber bolt carrier assembly allows you to quickly change to a 10.5", 14.5", 16.5" or 18" barrel in .223/5.56 or 6.8 Remington SPC. The ACR comes standard with a 16.5" cold-hammer-forged barrel that has an innovative coating to enhance longevity and a birdcage-style hider to control muzzle flash. ACRs have an adjustable, two-position, gas-piston-driven operating system supported by hardened internal bearing rails. Each has fully ambidextrous controls and a high-impact composite lower receiver with a textured magazine well and modular grip storage. This model has bullet button receiver for California compliance.
