How difficult to get Jr. stock set for 20g 870

[DELETED]

My mother and sisters are thinking of getting into hunting. So, I figured I should get them a gun . I noticed that Rem 870 express is not too expensive and that they come in a jr version. However, I want to get the combo 26"/20rifled so one of them can help me hunt deer. No jr version in this combo. So, how hard to swap a jr length of pull stock onto this combo and how hard to find these jr stocks? Thanks

I would post a want ad in the EE forum first. It is not that hard to find them. If you don't find one here there is always ebay. Last buy not least boydboys.com has replacement wood stocks for the 20ga and I am pretty sure they will make you a jr version.
