I have a friend who is an HK dealer. Some rich guy bought one and the dual sighting system. Being the typical rich guy he didn't want to sight it in so he asked the dealer to do it. I lucked out as he was to busy so he handed it to me with free ammo. How do you pass up a deal like that? IMHO they are damn fine rifles. It was 3 shoots through the same hole at 100 yrds. I only had access to a 300 yd range. At 300 it was 1.8" for 3 shots. They are pricey but if you can afford it get one. I don't really care for the thumbhole stock design but that is part of ATF's dumbass rules. There are a bunch of accessories you can buy but being HK the price tag is high for them too.
