  • the bolt is locked in its closed position when handle 25 is locked within the enlarged portion 32 of slot 30.
  • the handle 25 is disposed in its locked position in enlarged portion 31 of slot 30, the bolt is locked in its open position. With the bolt handle rotated to the unlocked position as shown in FIGS. 2B and 3B, the bolt 21 is freely slidable from left to right and vice versa.
  • Bolt handle 25 is provided with a sight passage 33 which allows sighting along the front and rear sights 15 and 16 when the bolt handle 25 is disposed in an unlocked position.
  • the sight passage in handle 25 is disposed in transverse relationship to the line of sight defined by from sight 15 and rear sight 16 thereby affording a ready visual indication of the locked condition of the bolt.
  • a rotatable latch 34 is pivotally mounted on pin 35 within the hand grip portion 3 of magazine housing 2. Furthermore latch 34 is biased in a clockwise direction toward latching position by a compression spring 36 to cause the latching surface 37 of latch 34 to ride underneath the latching surface 38 formed in magazine 4. Thus as shown in FIG. 3, the magazine 4 is held in its service position.
  • a spring 40 is provided which is of the compressional type and which functions in known manner as is obvious from FIG. 3.
