Hi there!
I got the chance to try out the Cyclone Impact Grenade at an airsoft game last weekend, and so far, I'm quite impressed with it! However, I've been told by some knowledgeable people that Cyclones have the tendency to break when thrown too hard; the weak point, from what I've heard, is the plastic ring the holds the bottom on.
Being an electrician, I'm knowledgeable about a number of different tools and materials as part of the trade. One of these materials that immediately came to mind, is something called "
Rubber Splicing Tape". This tape is basically a roll of rubber that, when wrapped repeatedly around something, sticks to itself, and insulates electrical equipment quite well - far more than electrical tape.
Being rubber, I had a brainwave, and I was thinking that it may also work well as a protective layer for the plastic cap; the top and bottom of the grenade is rubber, and thus can take the impacts of a heavy throw. By wrapping the ring a few times, while being mindful of the gaps which are important for removing/attaching the bottom, I think it's going to make a big difference in its longevity.
Unfortunately, I don't really have a way to test whether this fix actually helps or not (as doing so would be breaking it). However, after doing a few test drops, and noticing a difference in its impact, I think it's a good idea. The roll of tape is roughly $6.00 at your local hardware store, and one roll should be enough to do a dozen grenades!
To apply, simply hold one end with your thumb, and wrap it
very tightly. Wrapping tightly causes it to fold inward, which is handy since it protects the corners from damage. When wrapping, ensure that you are mindful of the gaps on the top, which is where the base of the grenade would fit.
I should also say that there's no reason why you can't wrap this around other parts of the grenade, or even wrap other breakable equipment! You could also use it to make a cheap-man's magpull. :P
Hope this helps!

Here's the magpull idea I had. :P
