Feeding The recoil stroke concludes when the Buer halts the Bolt Carrier

Group. The Recoil Spring, 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 top of the Magazine and directed into the chamber by the feed

lips of the magazine and 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. The bolt carrier group is

now again in battery.

4.7 OPERATING CYCLE

The following describes the operating cycle of the R.E.P.R. in semi-

automatic mode.

Firing When the Trigger is depressed, the sear is disengaged from the

Hammer allowing the hammer to be driven by the Hammer spring

to strike the Firing Pin. The Firing Pin strikes the primer, ring the

chambered round.

Unlocking Propellant gasses are tapped o at the gas port and travel trough the

gas block to the nozzle. This gas drives the piston cup back from the

nozzle, in turn driving the operating rod to strike the carrier key. This

initiates the rearward movement (recoil stroke) of the Bolt Carrier

Group. As the Bolt Carrier travels to the rear, the Cam Pin rotates the

Bolt, thus unlocking it from the barrel extension.

Extraction As the Bolt Carrier Group continues through the recoil stroke the

expended cartridge is drawn from the chamber by the extractor.

Ejection Once the expended cartridge is clear of the chamber it is ejected

from the weapon by the spring loaded Ejector.

Cocking Semi -As the Bolt Carrier Group continues to the rear it cocks the

Hammer which is initially retained by the Disconnector. As the

shooter disengages the trigger, the Disconnector releases the

hammer allowing it to be captured by the Trigger (this is known as

Reset).

Auto - 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

ring the round. When the trigger is depressed and held, the weapon

will cycle continuously through the ring 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 re again until the trigger

is pulled.
