These are the right size, 3-4", and easy to see at 10 and 25 yards but are not splatter burst targets, which I thought they might be. Fine for daylight hours. I was able to zero my 507C at 10 yards using just one of these. The concentric circles make fine adjustments pretty easy.

I have tried just about every other Holosun optic, 509T, EPS, 507 ACSS, 507Comp, EPS carry and finally landed on the one that was there all along. Unless you are in the field a lot, you do not need a closed optic reticle for EDC, which I have learned, print considerably more (eg EPS and Trijicon RCR) than the rounded open 507C, where I have finally settled. The green far better than red in my view and a 2 MOA is right for anything under 15 yards, and who or what are you gonna shoot beyond that unless you are in competition? Manual brightness mode is mandatory as the auto mode will starburst most of the time. For EDC and self defense, this is a great optic, checks all the boxes. Value for money. Too bad they are made in China, but credit where credit is due. Save urself time and money and come straight to this optic first.

Amazingly effective in reducing sounds. Simple controls. On/off. Up/down volume. I wore mine combined with inner ear plugs for 2 layer hearing protection. Many folks do this. The problem is that the audio signal feedback from the headset is too quiet to hear thru earplugs. Eg, you cant hear easily when the device turns on (or off) as there is no verbal confirmation. Likewise step up or down on volume settings cannot be easily heard. I think you would have to set the headsets up without earplugs first and then put on. They are not blue tooth which on balance is a good thing. The clarity of sound through the headset was not better than my Peltor Sport 500, but sound suppression was better.
