It really good for the price. - SIG SAUER Romeo4S Solar 1x20mm Compact Red Dot Sight w/Mount

I have this on my GPR (General Purpose Rifle) which serves as my home defense and "duty" rifle. The glass is nice and clear and the dot is nice and crisp. The main reason I picked this up instead of an Eotech is the price, the battery life, and I feel is more reliable than a Holosun (my line of thinking is that if its good enough for the British SAS its good enough for me). The solar is a bit of a gimick as it is on basically all of the optics that have it, except for the Holosun ones with capacitors that can hold a charge from the solar panel.
