Re: mr1 internals help..
Dragonfly has not been available for a few years now. Someone has been trying to find a used one in the bst section here for quite a while with no luck.
Just a word of caution, beware of those ultralight strikers offered by others. All they really do for most people is cause recocking problems. It's the main reason we did not go with those when in the R&D phase of the Dragonfly.
