Tribull,
The stock M@g smooth reflector maximizes throw, but also maximizes the flaws in the beam pattern known as "optical artifacts". If you use a reflector with an "orange peel texture", the throw will be reduced somewhat, but it will reduce/eliminate the artifacts. You might want to consider a textured reflector, such as this one, from Fivemega:

I have a number of custom parts from FM, and have never been disappointed.
There are also options from Kaidomain.com:

SMO = smooth reflector, MOP = medium orange peel, OP = simply means orange peel, and from the photo it looks more heavily textured than the MOP.
The more texture there is in a reflector, the more diffuse the beam is, and the less distance that it will throw. If you have a couple of different reflectors, you can "switch up" the beam to adapt your M@g to different tasks - searching for something at maximum distance with FM's bi-focal reflector, for example, or trying to light up as large of an area as possible with a more heavily-textured reflector. Having aluminum reflectors also means that if you want to "soup up" your M@g later, possibly the only thing you will need to change in your light will be the lexan plastic lens, to a more heat-resistant glass one.
