Thanks for the informative post bud
but with all that said I feel the biggest problem was the fact that it doesn't have a clear lens its more opaque.... when I asked the guy why this was he told me it was so the light from the diode was more evenly spread throughout the beam removing hot and cold spots like you get with the cheaper lasers.....as im only using a air rifle a 100m is more than enough for spotting rabbits killing ranges are more like 40m downwards.
