I've not found any of the collapsibles nor the AR style stocks to be comfortable to shoot.
Of course, if this is just a picture gun that's not meant as a tool, leave it on.
My advice mirrors that above. Put the old style stuff back on and sell these to someone you do not like.
And then, go shoot the thing plenty. About the time you realize you've just destroyed lots of targets in comfort, the factory stuff will look a lot better.
