The first version of the new MSBS "Grot" rifle purchased by the Polish government was actually a special version for ceremonial parade use. In order to make the gun suitable to that role, a surprising number of changes were made to it - almost every element is different than the standard service version. The stock is fixed and given a heavy steel buttplate, the fire control system is semiauto only, the right-side magazine release is disabled, the sights and low-profile and non-adjustable, the charging handle is extended, the gas system is left off completely, the barrel is extended, a special grasping ring is added to the barrel, and the bayonet release is reduced in profile.
