Solid enough so far - Holosun 1x30 Red Dot & Green Laser

The main thing I like about this is its all metal construction and then its green 5mw laser. This laser will make it across a lake, I like to pair green lasers(more range) with red dots to make a better contrast between aiming points when aiming down sights. So far mine seems pretty durable, but I'm having to tighten this thing down quite a bit to keep it from having a forwards backwards play on all of my pic rails. Also the flip open covers seem to rotate pretty often, meaning i have to rotate them back into a proper orientation.
