moved forwardly to uncover notch 24 thus as the cocking levers ride off sear corner 41 at the terminus of cocking ramp surface 40 they are free to spring forward into notch 24 as their associated firing pins 16 are propelled into firing impact with ammunition round primers as the discharged firing pins revolve through the firing position their cocking levers are cammed back onto safing ring cam surface 20 by a ramped end portion 24a of notch 24 thus restoring the firing pins to their pre cocked conditions it is seen that by utilizing a single cam driver post 70 to actuate both the firing and safing cams the two cams are positively intercoupled as they pivot between their respective armed and safe positions consequently there can be no ambiguity in their movements and positionings they are both either in their armed or their safe positions if a cocking lever is riding on the cocking ramp surface near the sear corner when the firing mechanism is converted from its armed condition to its safe condition it is seen that as the firing cam swings forwardly the safing cam swings rearwardly to pick up the cocking lever before its firing pin can impact the ammunition round primer it will also be noted that by virtue of the transverse orientations of the terminal portions of the slot cams the safe and armed positions.
