Barrett's MRAD adapts to a variety of user needs without sacrificing performance. With unfailing accuracy, this bolt-action system continues to define a whole new class of long-range precision rifles. It features a changeable barrel system that can be removed by simply loosening two bolts using a standard Torx wrench. Besides reducing maintenance and logistical burdens, this unique design allows for user level caliber interchangeability and serviceability with the MRAD rifle's barrel kits. The MRAD also features a fully adjustable match-grade trigger module, which is user accessible. The thumb-operated safety can be configured for left or right hand operation and its ambidextrous magazine release can be used intuitively while retaining a firing grip and cheek weld. Its forward receiver is drilled and tapped for accessory rails to be mounted at the 3, 6 and 9 o'clock positions.
