Unscrew
the magazine cap. This also holds the barrel on.
Pull
the barrel straight away from the receiver.
The
metal object is the magazine spring retainer. With some work (or not)
it will pull out. There is also the plug, spring, and follower.
This
is the spanner wrench that you should have for your chokes.
Use
the spanner wrench to unscrew forearm cap. Once removed, the forearm
will slide off the tube.
To
remove the trigger assembly, use a punch to remove this pin. Then
pull the trigger assembly out of the receiver.
Next
we remove the ejector. Use your thumb to depress the rod enough to
lift it off the pin and then slide it out the front.
The
slide arm bridge screw must be removed before removing the bolt assembly
from the receiver
Pull
the slide arms off the tube, but take care to not allow the bolt assembly
to fall freely.
Hold
it together so the slide arm bridge (circled) does not fall off. The
firing pin and firing spring are under pressure and the slide arm
bridge holds them together.
Keep
pressure on the firing pin while lifting off the slide arm bridge.
Everything
should be taken part enough for a proper cleaning. The trigger assembly
may be covered in the future.
