To take the cylinder unit out, pull back the charging handle along with the latch on its left side.
The cylinder unit will slide along with the charging handle.
After the cylinder unit is removed, the charging handle can also be taken out by pulling it out all
the way and then tilt it upward. To remove the inner barrel, use a plastic rod and insert it from
the muzzle end. Run the rod along the inner wall of the outer barrel until it touches the tip of the
inner barrel, then push the inner barrel out.
