Barrett MRAD
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. The MRAD is based on the Barrett 98B with a number of modifications and improvements. The Barrett MRAD was named the 2012 Rifle of the Year by the NRA.
==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.〔 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.〔 Additional features of the MRAD include a single-button length-of-pull adjustment, a bolt guide which acts as a dust cover to reduce debris entering the action, a trigger module which can be removed without tools making cleaning easier, an ambidextrous magazine release, and the ability to accept standard M4/M16 pistol grips.〔
The MRAD includes an upper receiver that can tilt on its take-down pin like an AR to allow for easy maintenance in the field.
With match grade .338 Lapua Magnum ammunition the MRAD is capable of 0.5 MOA (minute of arc) accuracy at a distant of up to 1500 meters. With standard ammunition the accuracy drops to 1 MOA.〔(Barrett MRAD ), Shooting Illustrated.〕
