Feeding- e recoil stroke concludes when the buffer halts the bolt carrier group.
e recoil spring, which is compressed during the recoil stroke, drives
the bolt carrier group forward commencing the counter recoil stroke.
As the bolt carrier returns forward the next round is stripped from
the magazine and directed into the chamber by the feed ramps.
Chambering- As the bolt carrier group continues the counter recoil stroke the round is
seated in the chamber.
Locking- As the bolt carrier group completes the counter recoil stroke the bolt rotates,
locking into the barrel extension. e bolt carrier group is now back in
battery.
Cycle of Operation in the Automatic Mode:
Automatic versions of the M6 series of weapons are only available to Military and Law
Enforcement Agencies. When the weapon is to be fired, the user can rapidly select either
Automatic or Semi-Automatic modes of operation. When the user selects automatic, the
following cycle of operation occurs:
Firing- By depressing the trigger the trigger engagement is disengaged from the
hammer sear allowing it to be driven by the hammer spring to strike the
firing pin. e firing pin strikes the primer, firing the chambered round.
Unlocking- Propellant gasses are tapped off at the gas port and travel trough the gas block
to the nozzle. Exiting the nozzle gas drives the piston cup back from the
nozzle in turn driving the intermediate rod and operating rod to strike the
carrier key (total travel of the piston system is approximately 0.6 inches. is
initiates the rearward movement (recoil stroke) of the bolt carrier and bolt. As
the bolt carrier travels to the rear the bolt is rotated unlocking from the
barrel extension.
Extracting- As the bolt and bolt carrier continue in the recoil stroke the expended
cartridge is drawn from the chamber by the extractor.
Ejecting- Once the expended cartridge is clear of the chamber it is ejected from the
weapon by the spring loaded ejector.
Cocking- As the bolt carrier group continues to the rear it cocks the hammer which
is retained by the auto sear. Concurrently the rear of the bolt carrier will trip
the auto sear releasing the hammer and firing the round. When the trigger is
depressed and held, the weapon will cycle continuously through the firing
sequence until the trigger is released or the magazine is depleted.
When the user releases the trigger, the hammer is caught by the hammer/
trigger engagement surface and does not allow the weapon to fire again until
the trigger is pulled.
