The Barrett MRAD or Multi-Role Adaptive Design is a bolt-action sniper rifle that was designed by Barrett to meet the requirements of the SOCOM PSR.[4] The MRAD is based on the Barrett 98B with a number of modifications and improvements.[5] The Barrett MRAD was named the 2012 Rifle of the Year by the NRA.[6]

Design

After the United States Special Operations Command (USSOCOM) announced their desire for a new Precision Sniper Rifle in December 2009, Barrett created the MRAD in accordance with the specifications laid out by SOCOM.[4] Building off of the successful Barrett 98B, the MRAD features multiple improvements such as a folding stock which allows the rifle to be transported more easily. When folded, the stock latches around the bolt handle which increases the security of transporting the rifle without increasing the width as unfolded.[2] A major MRAD feature (and requirement of the military PSR solicitation) is a user field changeable barrel/caliber capability. Loosening two Torx screws in the receiver allows removal of the barrel from the front of the receiver/handguard. With only a simple bolt face change, and in some cases a magazine change, caliber may be changed. The factory headspaced bolt face is provided with each barrel. Barrel/caliber change can occur in less than two minutes. In addition to the typical military requested calibers of .338 Lapua Magnum, .300 Winchester Magnum, and .308 Winchester calibers, Barrett also offers popular caliber conversion kits in .338 and .300 NORMA, 7mm Remington, .260 Remington, and 6.5mm Creedmoor. Barrel lengths are offered in 17" to 26", but not in all calibers. Barrels are available in fluted and heavy profiles. The trigger module can be removed without tools providing access to user adjustable trigger pull weight and over travel, and making cleaning easier. Additional features of the MRAD include a single-button length-of-pull adjustment, adjustable cheek rest height, a polymer bolt guide acts as a dust cover to reduce debris entering the action, a user reversible AR-15 style safety, an ambidextrous magazine release, and the ability to accept standard M16/AR15 style pistol grips.[2] Early MRADs had 30MOA slope full length 21.75" standard 1913 Picatinny rail on top of the receiver/handuard. Current MRADs feature 20MOA slope rail. Shorter 2"-4" Picatinny rails sections may be user positioned at 3, 6, and 9 0'clock at several fore/aft positions along the handguard. MRADs are offered in several Cerakote colors; all barrels are black.[7]

Similar to the M16/AR15 rifle, the MRAD upper and lower receivers can be separated by pushing out rear and front two take-down pins. Pushing out only the rear take-down pin allows the upper receiver to tilt on its front take-down pin like an AR to allow for easy maintenance in the field.[8]

With match grade .338 Lapua Magnum ammunition the MRAD is capable of 0.5 MOA (minute of angle) accuracy at a distances of up to 1500 meters. With standard ammunition the accuracy drops to 1 MOA.[9]

SOCOM PSR

The particular model of the MRAD that was submitted for the PSR trial was fitted with a {{convert|24.5|in|cm|abbr=on}} barrel, and weighed {{convert|14.8|lbs|kg|abbr=on}} (without an optic)."[4] The Remington Modular Sniper Rifle was selected as the winner of the PSR competition.[10]
