The rear sight is nearly identical to the TM. The TM has a dovetailed rear sight with a grub screw to hold it in place. This looks to be the same, if not identical, as this one has windage markers, the TM does not.
" dummy bolt cover which can be pulled back" I don't think this means it moves when you pump. Again, just like the original TM, the 'bolt' is just a plate of metal glued into the receiver, if you break the glue you can move the piece back and forth by hand. CYMA may have put in a spring, which would be a nice addition to the design.
