760 Barrel Change

[Flatcar1]

I am modding a newer model 760 for my grandkids with a rifled barrel. Is there any thing I should watch for when I start the disassemble. I am trying to be proactive instead of posting after making a goof. I have printed out the exploded view and have been inside a 2100 without any troubles but I cant really find any "how tos" on the 760 disassembly in printed version. I have seen some videos. I just wanted to check here with the experts first. Thanks for being here.

Yea, watch out for the safety...  After looking for some two hours, I found mine on top of the fridge... Next would be to relieve the hammer spring and guide... They like to fly too...
