You guys need to get these up and running down south! Definitely my favorite black rifle from what I've handled and shot. Surprisingly different from an AR-15. Click the pic for a quick run and gun video. [ame="http://youtu.be/3mF42dkKfbI"][/ame] Right now I've got it with a 3rd party full top rail, Leupold HAMR and delta point, surefire flashider and troy flip ups. I regret selling my surefire scout light. The inforce replacement isn't half as nice. I'm tempted to try a Knights super slim rear sight on this setup, but I'm not sure how well it would work so close to the eye. One of the things with a bull-pup is there's never a very large sight radius. Has anyone else used iron sights on an RFB or similar setup and has advice?
