4Sevens Preon Modification

Those of you that read my review of the 4Sevens Preon 1 saw that I had a problem with the 4Sevens Preon clicky tailcaps.  It seemed that they collected every piece of dirt or grime within a 20 mile radius.  I had numerous issues with the clicker sticking in one position or the other.  I had heard better things about the tailcap mechanism from the Streamlight Microstream, but I wasn’t too impressed with the light itself.

But what if you could combine the emitter and the guts of the 4Sevens Preon with the body and clicky tailcap(push button) of the Streamlight Microstream?  I hear that you can.  Bear in mind that I have not verified or done this myself yet, but I have read this on three different occasions from three different sources.

I understand that it’s not a quick and easy removal, but it is possible.

Most recommended placing the Microstream body in a vise and using a heatgun(or hair dryer):

 Slowly heat the threads and after every couple of seconds you need to try to twist the head off.  It’s all about slowly heating and twisting the head every couple of seconds. That way you’re not melting the body and head together.

This is not the only way. Someone else had this advice:

Ziploc baggie, boiling water, and a (very) small strapwrench does the trick every time.

Basically, with a little patience you can combine the two lights.

When I get my Microstream, I’ll get some photos while I do the work and let you all know how it goes.

Have any of you already done this?  I’d love to see some pics…
