Popis:	Rifles of MSBS-5.56 system are equipped with a mechanism for an easy barrel changing, what was one of basic assumptions of system modularity. But barrel changing, although possible even under field conditions (with the use of basic tools), causes displacement of shot pattern mean point. Due to the fact that the sights are mounted on the upper receiver, it is important that this displacement is as small as possible. In order to determine the mean value of displacements for the pattern mean point and the construction parameters affecting them, a series of firings were performed using a laboratory stand and shooting range. Both repeatability of fixing the same barrel (ex-changeability) and other barrels (inter-changeability) were taken into account.
