NcStar model D4B holographic sight. It's a copy of the Hakko MKIIIBED35. it has seven brightness setting and 4 recticles, built in weaver mount, and is 1 MOA. comes with the box and papers, lens cover, and lens cleaner and an extra new battery. I also have a cheap no-name carry handle cantilever mount. I'll sell both for $60 shipped or trade them for a 3X9 scope.
