Yep, what quick said. I always go by the NEF # on the Walmart listing and then cross reference to the NEF web site and read it there. Sometimes, like with the SC2-Y43 combo, you won't be able to find it on NEF because it is a special run item. You will also find differences when you check descriptions on the guns listed on SportSouth. I usually check the specs in all three places and if I can't figure it out then I call CS at NEF. Hope this helps. Also, check the accessory barrel chart on the NEF site. Some barrels come with open sites as accessory barrels, but they don't offer it on a complete gun. Example 30-06.
