i'd stay away from the Mossberg 715,,,,had one,,,took it to the range once,,,sold it the day after at a loss,,,,that POS was going to drive me nuts,,JAMMOMATIC would be a better name for them,,,sure there lots of guys who will yell you to fix and fix that to get them to work,,,i think it SHOULD be able to function reliably from the factory...if you can find the Ruger,,,you'll do much better....even a nice 10/22 is a lot of fun...
