A '''muzzle reference system''' ('''MRS''') is a device used on most modern [[Engineering:Tank|tank]] guns and some [[Engineering:Artillery|artillery]] systems that measures the bending of the barrel due to heat, gravity and other issues. It normally consists of a [[Physics:Laser|laser]] device and detector mounted at the breach end of the gun, often co-located with other optics like the gunner's sight, and a mirror at the muzzle. By measuring the deflection of the barrel, corrections can be applied by the ballistic computer to correct for changes as the gun is fired.
