Its probably stupid to ask, but...
is it a very "self-explanitory" installation??
Yeah it's pretty simple, only hard part was getting this little metal pin in. It will take some time though especially if you want everything to work right, like the charging handle and the hop-up.

you will havt to do the new hop up unit, if u dont know whow install a hop up into the barrel it can be hard.
