Juat bought an M4 and the beam is quite oval, to the point that I really notice it and it annoys me. It looks oval with the 225 lumen lamp and the 350 lumen lamp. Is this a characteristic of the M4 or does mine have a problem?
Mossyoak you are very generous. I need to add that the ovalness I'm noticing is not when I shine it against a wall, it is when it is outside and actually being used.
