This will reduce pressure in the system enough to allow proper functioning without

excessive recoil on operating components. NOTE: When using a suppressor with the RFB,

it will be necessary to perform cleaning operations and basic maintenance more frequently.

Avoid use of Subsonic Ammunition in the standard RFB when using a suppressor. See

note in the warning section of this manual.

Unloading and Clearing the Rifle

It will be necessary to unload your RFB for storage, transportation, and disassembly

purposes. To unload the RFB, first ensure that the selector is on safe. Keeping the rifle

pointed in a safe direction and your finger off of the trigger, remove the magazine by

pressing the magazine release and pulling out the magazine. Resting the butt of the RFB

against your hip, pull back the charging handle with your support hand and maintain

tension on the charging handle. With the rifle supported in this way, carefully reach back

and move the bolt stop upward, and slowly relax tension on the operating handle to lock the

bolt open. Grasp the center of the rifle between the pistol grip and the magazine well and

turn the rifle over.

Use your support hand to push on the bottom of the Bolt Stop to ensure that it

does on close on your fingers, inspect the inside of the rifle and make sure that there is no

live ammunition or brass cases in the extractors or chamber. If a case is held by the

extractors, manually cycle the action to eject it from the ejection chute. If the case is

damaged or will not eject, hold the bolt stop open and press on the case body to free the

case from the extractors, then turn the rifle over to allow the case to fall free.

Field Stripping

If the rifle has been fired, wait a least one-hour for the metal components to cool

before attempting disassembly. Do not use cleaning solvents or any lubrication on any

metal surfaces while the rifle is hot as this will cause microscopic fractures in the surface of

the metal and reduce service life. The rifle should be pointed muzzle down at all times

during disassembly. Do not point the rifle upward when disassembled, as resting it on the

cocked hammer and the firing mechanism may potentially damage them.

Figure 30: DO NOT rest disassembled rifle on the hammer!

In order to field strip the RFB for cleaning, first ensure that the rifle is unloaded by

removing the magazine and cycling the action. Put the rifle on safe, remove the magazine

and pull back and hold the charging handle. Lock the bolt back lifting and holding the bolt

stop and then slowly release the charging handle. Apply and hold upward pressure to the

bottom of the bolt stop to prevent the bolt from closing on fingers. Look inside the magazine

well and feel to ensure that there are no rounds in the chamber. .After checking the

chamber, allow the bolt to go forward and place the rifle muzzle down on a non-marring

surface. Do not dry fire the rifle, as the dropped hammer will prevent disassembly. Using

the nose of a dummy cartridge or similar object, push both the Rear Assembly Pins from

the left side. (Note: Do not use excessive force on the Assembly pins!) Pull the pins out the

right side as far as they will go.

Figures 31 & 32: Use the nose of a bullet to push out the pin.: Be sure to pull out the assembly pins

out as far as they will go

Giving a firm downward slap on the back of the pistol grip will rotate the grip

downwards, exposing the receiver. If the grip does not rotate down, verify that both

assembly pins are out all the way and that the hammer is cocked. Then try again.
