Wish I could afford an EoTech or an AimPoint. However, I can't fit it in my budget at this point. So, I've narrowed down my choices to either the Bushnell TRS-25 or a Sightmark holographic. Both are close to the same price, around $100. Does anyone have experience with either of these optics for an AR rifle? I've researched them both and they both have good and bad reviews. The Bushnell appears to be waterproof whereas the Sightmark is water resistant. Thoughts and opinions on these two optics are appreciated. Thanks.
