Hassle-free returns & exchanges.  Sold individually. Replacement O-ring for: Dimensions: Steve Says: O-Ring for RRT LaunchersIt's one of those little things that can stop your training dead in its tracks. Handheld dummy launchers (like the RRT) don't work very well without the o-ring. The o-ring is what keeps the gas inside that is created by the load and it shoots the dummy in the air. I have seen o-rings last for years and I have seen them fail in weeks. Always keep a few spares on hand to replace yours as needed.  Steve Snell

We use the DT Dummy Launcher often and noticed the launch distance was decreasing. After a new O-Ring its back to launching 100 yards.

Bought the o-rings for the launcher to have extras, since I wasn't sure how long they lasted. I bought the launcher because I broke my leg in a hunting fall and was in a cast. I could operate the launcher, and my dog can retrieve and loves the extra training. Since he's an upland dog, pheasant mainly, dokken needs a pheasant dummy for the launcher.
