Blaster toys are available in more places than just the United States, so I've been perusing the latest issues of various toy magazines. Here's a few tidbits from the United Kingdom! We'll start with Toy World Magazine, which has advertisements for Petron Sports' Sureshot line of sucker products.
In addition to the upgraded crossbow, Petron has a new, spring-powered sucker dart rifle. It's pump action, and while I imagine it's a dart pusher (as opposed to a plunger) launching the plastic dart, it could still be interesting to look at.
