I am a huge fan of the normal M4 iron-sights, but I think that I want to get a red dot for this years Berget. I stumbled over the Element Type 52. Its price is ~80€ at a german retailer.

Does anybody have experiences with this model, or can recommend another red dot?
And the second question

I'm starting to hate my Bollé x900 goggles because of their uncomortable fit and unclear glass. Now I want to switch to a nice pair of glasses. I heard that Swiss Eye makes good ones.
What is your opinion of that company and their products. Can you recommend a specific model?
