The NERF DART TAG SNAPFIRE 8 blaster features one-hand firing, an essential element when players are on the move during competition battle. This semi-automatic blaster allows competitors to load darts into the front and then cock and fire darts as the front barrel revolves with each trigger pull. The DART TAG SNAPFIRE 8 blaster also enables players to adjust the tension level for increased speed and distance. Includes 8 Velcro tipped DART TAG darts. Available at most major toy retailers nationwide and on HasbroToyShop.com.
This appears to be a new concept, involving the blaster priming when you pull the trigger, as in this. I'm also curious as the the addition of an adjustment for range. I have absolutely no idea why you would need to have less power, other than maybe the fact that it has less tension on the trigger resulting in a lower rate of fire... We'll have to wait and see.
