Iron sights

I've gotten iron sights on my Sabre Defence rifle in the past few weeks. I wanted the longest sight radius I could get and the barrel diameter at the end made this a challenge, .728 stepped to .705

Chuck Haynes in New Market bored out a .625 ID sight base to match the barrel and installed set screw on the bottom to anchor it in place. It works very well with the DPMS removable rear I picked up from Shannon Thrasher at Athens Guns.
