Mauser06 Practice makes perfect.
The Ruger's can be tricky to disassemble and reassemble.Once you get the hang of them it's not to bad.It's been along time since I took one apart.I would probably have to study it again.I faintly remember there was book or booket with tips explaining the easy disassembly and assembly for the little Ruger's.I haven't seen this booklet lately. The Ruger's owners manual gives step by step.There is bound to be someone who can give you and your dad pointers on these little jewels. It's easy once you get the hang of it.
