Awright, I have recently opeaned up my tsd m87 and (considering that there are none) have decieded to make a guid on the subject.
Please keep in mind that #1: This is the first time that I have written anything like this so it is possible that I missed something. Use your head and keep an eye out for anything that might be worth remembering while your taking it apart. And #2: this gun was not made to be taken apart so (even though it can be taken apart) there is a risk of stripping screws. I have taken this shotgun apart and put it back together twice now, but I think that thats about the safty limit before your screws start stripping.
Also, I'm sory that the pictures are so small, but they arn't supposed to be. If you click on them, then they will opean to their full size.
So here it is:
this is said shotgun
first you pull off the rubber but plate, unscrew this screwand pull the stock off
there is a cover over the reciever. Pull it off
go to the foregrip, take out the two screws keeping it in
pull the sides of the foregrip apart starting with the right one
take out these screws
go to the rear sight, take out these three screws, and lift off that cover that you see
you may now pull the outer barrel off
take out the inner barrels and unscrew these screws
if you don't know what to do with this step then you've got issues
thing that restrains the bbs until you cock the gun
the three inner barrels. Mine had some kind of wierd sticky grease in them that I had to remove
on to the rear assembly
this is the thing that keeps the cocking handel forward after you've cocked the gun. Take it out
take out indicated screws
pull the trigger assembly and the side off the gun
opean the loading hatch
the cylinder. Mine had a ton of junk in it that had to be removed
remember to clean the gun before you put it back together.
to put it back together reverse the process.
I'm not responsible for anything that goes wrong.
