Ok, please, NO laughing! Got a large bolt knob from Savage. Now, to replace, all I need to do is remove the end cap with an Allen wrench, slide original off, slide new one on and replace end cap? Is there spring tension on this, or anything else I need to be aware of? Thanks for your help, I am quite familiar with handguns, but not rifles. BTW, this older Savage does not have the Accutrigger, if that makes a difference.
