How to disassemble the retractable stock.
Place the butt stock
between your knees with the recoil spring assy pointing
away from you, and push the circlip off using two
screwdrivers if it is the "C"-type circlip (6). If it is a
snap ring you simply use the snap ring pliers. In stead of
placing it between your knees you could place the stock in
a vice but I don't recommend this as it would be easy to
damage the stock.
After
removing the circlip (6) remove the locking ring with
spring (5) and the clamping lever (4).
Remove the
protective cover (3) from the back plate (1) by pressing
the tabs in with a pair of pliers and pulling the
cover off.
Now you can
slide the butt stock (7) with the protective cover (3) and
the gripping lever (2) off from the back plate (1).
Removing the
gripping lever from the guide rails might be a little
tricky, place the gripping lever in the guide rail
locking recesses used to lock the stock in the extended
position. Then wiggle it a little while carefully bending
the guide rails very slightly apart, and the gripping
lever should slide off.
How to assemble the retractable stock.
Slide
protective cover (3) onto butt stock (7).
Insert
gripping lever (2) in the recesses and push butt stock to
half length into the back plate (1).
Press the
protective cover (3) into the back plate (1).
Attach
clamping lever (4) to the buffer housing so that the two
lugs engage properly in the gripping lever (2).
Insert
locking ring with spring (5) so that the end of the
tension spring engages in the bore of the locking ring
(5).
Insert
circlip (6) or snap ring(6).
Done!
Pre-tensioning the spring in the clamping lever.
Retract butt
stock all the way up to stop.
Swiwel
clamping lever to the left.
Swiwel back
clamping lever all the way to the stop.
Press
ratchet into the notch of the locking ring and swiwel back
clamping lever.
Repeat this
process until the clamping lever is under spring tension.

*Please note
that there are some types of stock that might disassemble in
a slightly different way, but I think the basic principle
is the same. Examples are the HK33/93/94/MP5 stock. I
haven't tried to disassemble any of these yet.
If you assemble your retractable butt stock
incorrectly it might collapse on you while shooting,
causing severe injury.
If
you choose to proceed, you do this on your own risk, and
if you somehow manages to break or otherwise ruin your
stock, well that is your problem. If you are not 100% sure
that you can manage to do this, don't do it, or pay
someone competent to do it for you.
