kj,
Here is one you may want to start saving for its not a double but its pretty nice.
Rifles—firearms with helical grooves carved into the barrel to impart greater range and accuracy—have been in military use since the Seven Years War in Europe. While originally used only by sharpshooters and hunters, today’s rifles are the standard arms of the modern infantryman. Of course, none of them get to carry the most expensive rifle in the world.
VO Vapen Royal Collection United Arab Emirates Edition rifle
The gun is a product of Viggo Olsson, the Swedish gunsmith who founded VO Vapen in 1977. Called the H.H. Sheikh Zayed Bin Sultan Al Nahyan Mosque Rifle, it was created as a tribute to its namesake building in Abu Dhabi. The rifle was modeled after the mosque’s impressive chandelier and features gold inlays and thirty-six diamonds of various colors. The exclusive rifle is valued at $825,000. Olssen has also produced 100 Royal Collection United Arab Emirates Edition rifles priced at a somewhat more modest $525,000.
