The red and gold chequering provides much better visibility, particularly for crews working on roads.

A crossbolt was added, and chequering of the pistol grip and fore-end became standard.

The forewings are yellow marked with brown fascia and apical streak with brown chequering on the fringe.

The changes included dropping the controlled round feed feature, a change to the basic stock shape and the use of impressed chequering rather than cut chequering.
