I have had this Burris FastFire II reflex red dot for several years. It does a great job for what it was designed such as fast target acquisition in things like action pistol, practical shooting, IDPA or PPC. But that is not what I have wanted to do with it ever since I got it. What I want to do is informal plinking at small targets out to 25 yards and maybe some hope and pray shooting at further distances. The problem has always been the size of the dot. It is supposed to be a 4 MOA dot but under the lighting conditions I usually shoot in the dot "flares" to much larger than 4 MOA. Have discussed it with Burris and they even replaced the first one I purchased but the replacement acts the same way. It appears it is sensing too much light/brightness is present and cranks up the intensity to a point making the sight unusable for my purposes. I have had it on a couple different pistols and get disgusted, take it off and put it in the drawer and then get it back out because it is a $200 sight and I can't leave something like that in the drawer. I have been playing with ways to cut down on the "sensed" light it is detecting there by lowering the intensity of the dot. If I put my finger over the sensor port that works pretty good but it is not very convenient. ha. I tried masking tape both cream colored and blue. That worked a little better but not good enough. I put electrical tape completely over the sensor port and that cuts out too much light. What I have now is a temporary rig where I put electrical tape almost covering all of the port. That accomplishes the task of reducing the sensed light just fine but is not very durable and a pain to get it just right. I thought if I spread this problem out here on the forum maybe one of you could come up with a better and more durable solution. The sight is presently mounted on a Ruger MK III Target. I notice that the new FastFire III has different setting for intensity but not the FastFire II. I know there are other sights on the market now that have solved this problem but I don't want to pay the money to buy another sight if I can figure a way to cut the intensity of the dot on this Burris. Any thoughts or ideas you might share will be appreciated.
