Red dot brightness?

Bill/OregonRed dot brightness?
Rather than keep stepping on MT's thread, I'll ask here. Are some brands of 3MOA red dots brighter than others, or is this a relative constant?

Some brands feature adjustable brightness which comes in handy with changing light conditions.

Bill/OregonThanks MAH. I have talked with several users and some say they have found the red dots they have tried to be nearly worthless in bright sun in spite of brightness adjustments. Others report their red dots work fine in all light conditions.

My Doctor Optic 3moa has different brightness settings that come in handy.

packrattusnongratusI think my RMR is a 3.25 dot size and it does well in sunlight. I think you need to test the real thing, precisely, that you want to buy. The better ones are expensive. What is the one Whitworth uses a lot of? They are a tube with dot inside. My memory doesn't do as well as I'd like. Ask him as they are on some of his really hard hitters. Be Well, Packy.

packrattusnongratusUltradot 30MM is what I was thinking earlier. Ask Whitworth if you want to talk to someone whom I know to have used it. It was on some heavy hitters if I remember correctly. Maybe our Moderator has used them. Be Well, Packy.

Uncle GrinchBrightness or lack of is exactly why I quit using my older Optima 2000 on my Ruger Mk II pistol. Works great in the shade.

Bill/OregonMike, I had that same issue with an older Bushnell red dot -- only useful in the shade.

sputsterFollowing earlier threads on red dots, I put an Ultradot 30 on my Bisley SBH. I have no issues in bright light, the dot can be turned up plenty to compensate.

The RMRs that I use are battery operated, have a 3.25 dot size and have worked exceptionally well for me.

Bill/OregonLooking at these again. I find I simply cannot see the factory rear sight on the SBH with enough clarity for hunting purposes.
