Assembling.
By reversing the operations for stripping the assembling of gun is readily and quickly carried out. The following points, however, should be noted:—
1. Be sure that gas chamber band is correctly inserted into its place in the radiator before barrel is pushed home, and that barrel is turned with gas port at bottom.
2. In replacing bolt and operating rod the cam slot in bolt is slipped over striker and feed operating stud is screwed into bolt as far as it will go.
3. After inserting bolt, rod, and charging handle, the charging handle is carried forward to extreme end of its stroke before gear casing is swung up into place and rack engaged.
4. The mainspring is wound up by engaging the rack and gear, disengaging the guard, and pulling back on the charging handle until the required tension is obtained. The gear is then disengaged, charging handle moved completely forward, gear re-engaged and guard pushed home.
5. To reduce tension of mainspring proceed as follows:—
Remove buttstock.
Disengage both guard and gear.
