Take-down and Maintenance
To disassemble the Professional
Training Weapon, first punch-out the
rear receiver pin until the stopper pin
(similar to the real M16) engages. The
stopper pin prevents the rear receiver
pin from falling out of the receiver, so do
not attempt to completely remove the
rear receiver pin from the lower receiver.
With your palm rested firmly on top of
the stock, push the charging handle with
your thumb to pivot the upper receiver.
There is a spring-loaded ball bearing
that holds the upper receiver securely in
place, so a considerable force may be
required to open the upper receiver.
After removing the cylinder unit, the
charging handle can also be removed
by sliding it all the way back then tilting
it. Replacement and upgrade cylinder
units will be available from your
Systema dealers shortly.

To remove the cylinder unit, pull the
charging handle back firmly while
ensuring the charging handle latch,
located on the left side of the charging
handle, is also released. The cylinder
unit will slide out towards the back as
you pull the charging handle.
Note that due to very tight manufacturing tolerance, the cylinder unit may be
initially difficult to extract. In time it will “break-in” and gradually becomes easier
to remove.
