This is the Nerf Rival MXVII-10K, which typically sells for $50-80 on eBay and other sites. It's a battery-powered blaster that shoots yellow ammo balls, which are easy to find for cleanup. There are 100-plus balls for each blaster. They work great, and don't jam like so many Nerf toys that use darts. I'm willing to take $40 for the pair, or $50 if I include the (rechargeable) batteries. Please email or call/text Tom at the number provided.
