Nerf Maverick Rev-6 + Barricade RV-10 for $29 with shipping

My sons have been asking for Nerf guns since they got to play with it when they were visiting their cousins but I'm not sure until when they are going to be hooked on them so I didn't want to purchase out right. But I saw this on Kids Dealz and the $29 price tag is doable so I got them the Maverick Rev-6 and Barricade RV-10. The RV-10 has a 10-dart revolving barrel which enables the shooter to keep firing at a faster rate while the Maverick has a quick-loading and quick-firing rotating barrel. I am not sure who would win when they go against each other. Now, I just have to keep my husband away from them because he's sure to revert back to being a kid when he sees the toys.
