This is an older Browe BCO when they were still made out of titanium. I've never had it on a rifle. If you aren't familiar with the BCO check it out online. It is a product improved ACOG. I have one on my regular rifle and it has been flawless. 

Retail on this unit is $1,850 and they are no longer made with a titanium body. 

I'm not looking for trades or offers. If it doesn't sell, I'm OK with that.
