SOFREP reviews the MRAD:

My first impression of the Barrett MRAD (Multi-Role Adaptive Design) straight out of the box was that Barrett had designed a beautiful rifle.  The rifle I received for my evaluation was a bolt action chambered for .338 Lapua Magnum.

The concept behind Barrett’s MRAD system, is that it provides the shooter with an adaptable modular shooting platform.  The MRAD can be re-configured to a variety of different calibers depending on the mission or application.

The 338 round was initially developed and sponsored by my community (The Navy SEALs) as an accurate long distance round.  I’ve fired half a dozen different platforms and I’m personally a big fan of the 338 Lapua round.  At speeds up to 2900 feet per second it’s a flat flying killer out to distances of 1500 meters.
