My suggestion , step up and buy the youth model 870 - 20 gauge , it's a lot easier to modified the Remington .. you fine lot more selection of stocks , chokes etc ...
I have the mossberg maverick 20ga youth myself. It's the same as the mossberg 500 except where the safety is located. Everything made to interchange with the 500 will interchange with the maverick 88. I really like mine it's a solid little gun.
