During photo shoot, we had an opportunity to learn MSBS
disassembly procedure. It is very similar to disassembling
of the MSBS-5,56B, although because of the obvious reasons
slightly different. It begins from unloading a weapon and
clearing chamber. Then, after a test shot, stock should be
folded and a button visible on the end of the upper receiver
must be pressed down. This allows to remove the stock by
sliding it downwards. Then, the bolt carrier group can be
removed. At this stage one needs also to take out a pivot
which connects lower and upper receiver (in front of the
magazine well, at the height of the charging handle) and to
separate them. It is also possible to disconnect a bolt from
the bolt carrier group and a handguard, but at this stage of
the disassembly no one neither takes out a charging handle
nor turns out a barrel (unless a user wishes to change it for
a longer or a shorter one). In order to reassemble a rifle, all
these activities in the reverse order.
