Cap Removal & Installation

For alternate action models cap must be in UP position for cap

removal. Indentations on opposite sides of the cap provide an

easy way to lift the cap out of the holder, using either the finger

nails, or cap extractor AT109.

Cap Replacement

Note that the cap has a pair

of round tabs and a pair of

long tabs which should be

used for correctly replacing

the cap in its holder. Using

the long tabs as guides,

slide the cap with the long

tabs moving into the slots

on opposite sides of the cap

holder. Then, the round tabs

will snap into notches on the

other two sides of the holder.
