I like the charging handle from the Ruger .22 magnum 10/22. I got the charging handle, complete with spring guide and spring from Brownell's. I cut off the crimped end of the guide rod, removed the spring and replaced it with a normal 10/22 spring. I ground the longer magnum guide rod to standard guide rod length and cut a little groove for a C clip. Inserted the C clip and replaced the assembly. It is a little bigger than the standard op rod handle, but not as huge as some of the other aftermarket handles.
