The rifle has a free-floating barrel and comes with a detachable flash suppressor and that allows for a screw-on sound suppressor.
The ejection port is on the right side and has a brass deflector that allows the gun to be fired by a left handed shooter without sending hot brass into their face. The brass shoots forward which helps if you are shooting next to someone because it stops the brass from being shot into their face also. The deflector limits the damage to brass casings making the brass easier to reload.
The MSG90A1 is made for the U.S. Department of Defense and used by some of the Hostage Rescue Teams of the FBI.
