Barrett MRAD, Bolt Action Rifle, 308 Winchester, 24 Barrel, Adjustable Folding Stock, Magpul MOE Grip, 10 Rounds, 1 Magazine, Includes Hard Case 18491 Designed with both precision and modularity in mind, the MRAD is equally at home on the range or on duty. Its monolithic upper receiver is machined from 7000-series aluminum, including a full-length M1913 Picatinny top rail with built-in taper for long range precision. With mounting slots at 3, 6, and 9 o'clock, its hand guard offers a rigid, highly adaptable interface for attachment of rails, electro-optics, and other accessories. Featuring a user-changeable barrel system, the MRAD can quickly and easily be converted to one of 7 different calibers or multiple barrel lengths by simply loosening two bolts using a standard Torx wrench; no gunsmith required.
