I just received my new Burris Fastfire II reflex sight and have some questions for those having experience with reflex sights. First, here is what it looks like:
http://www.burrisoptics.com/fastfire.html
This sight projects a red light beam from an LED (light emitting diode) onto the curved glass lens/screen. The screen has a coating on it that reflects only the wavelength of the light beam back toward your eye while letting all other light pass in either direction, so you can sight through it. The projected dot is supposed to be 4 MoA size. Put the red dot on the target, pull the trigger, bullet goes there (once zeroed). Simple, cool.
Questions:
1) The projected dot on the screen is a little "fuzzy". Actually, the edges look sharply, irregularly jagged. Is this normal? I think it is distracting, at least, for aiming. I guess I am spoiled by the sharpness of scope reticles. My first thought was, the jaggedness is due to reflections off small scratches on the glass screen. But I guess it could be from the LED lens/projection assembly. How to tell and what to do?
2) Mfgr says the intensity of the LED beam uses an ambient light sensor and brightens or dims the dot to suit light level - the sensor is in that little hole you can see in the photo centered just beneath the lens. Supposed to measure light in the direction of your target. Q: Could the fuzzy dot image be because the intensity is too bright? Maybe the intensity control is stuck on high? I can't see any difference, whatever the lighting (I guess that's the point of the sensor, but it may be too bright overall).
Do I call Burris or where I bought the unit (MidwayUSA)? How would I know that any replacement unit is any better?
Overall its a cool little unit - I think I'll like it once set to my liking.
