How many reticle option can we choose from this model?

The HS510C has 3 reticle options: 2 MOA single dot, 65 MOA circle only, and dot and circle together. Hope this helps.

Can you use this red dot on a Springfield xdm osp Pistol?

No this is a carbine/rifle sight look at the the 407/507

Is it water and fog proof and will it set a Browning silver slayer real?

The HS510c is IP67 rated. Complete protection against ingress of dust and airborne particles. Protection against water and liquids, up to and including immersion in up to one meter of water. It looks like your Browning does not come with rails therefore you just have to add a Picatinny rail mount. Hope this helps.

Does the solar cell recharge the battery?

No. But it doesn’t use the battery if it has solar. Been using the same battery that was in the unit when I bought for more then a year now with no problems and I don’t use the solar settings very often.

Best red for AR rifle on the market

Best red on the market. Shake awake is great stays on target. Once it’s sited in it stays there. The only rife red dot I buy. Clear glass nice dot.

Great red dot sight

I had been recommended to purchase this product by a friend who was using one. Once I received the product, I opened it. The box it comes in is very sturdy and Holosun provides all the necessary tools to do adjustments. It was easy to mount on my picatinny rail and I was off to the range to zero it in. It is fairly easy to zero in to if you follow the instructions. I had good groupings at 10 and 15 yds which is what I was going for. If you are looking for a good sight, I think you would be happy with this one. Thumbs up.

Great red dot

Perfect optic for my rifle. Co-witnesses right out the box with my iron sights. Nice variable brightness and shake awake feature is great.

Amazing clarity

Great red dot with amazing clarity and one of the few where the reticle does not bleed. I've had 1k dollar aimpoints that didn't look as good
