Best enclosed red dot - CORD Pandora PB-3 Micro 1x22-17mm Reflex Red Dot Sight w/Aurawake

I've had multiple acro's die on me thru training and department use. They fall apart when left in a hot cruiser. Also had one go bad thru a river crossing mission. Weve been running the pb3 on our side arm and rifle. The design is well executed and feels great in the hand. It doesn't have sharp edges to snag on gear.
