It's a niche item, and you would probably have to contact Knight's Armament first to see if they're manufacturing them for the civil market. If not, it wouldn't be too difficult to assemble something close to it by building it up from a stripped AR-10 receiver.
The M110 SASS uses the 7.62x51 cartridge.
No, at least not on official basis, nor are they using the SR-25 (which was the basis of the M110 SASS).
take it out of the freezer?
yes it is
Assuming the question is in reference to the M110 Semi Automatic Sniper System (SASS), and not the M110 self propelled howitzer, the answer would be 783 meters per second, which translates to something like 2570 feet per second, using the military issue 7.62x51 'special ball' M118LR cartridge. Different cartridges and loads will produce different performance results, and these will affect the muzzle velocity of the weapon.

According to GunsAmerica.com (gun auction site) you could get one for $6,000 plus transfer and it appears to be without the suppressor. Last time I checked GunsAmerica there was one going for $29,000, including a suppressor. Knesek Guns, Inc. is selling the M110 SASS for $29,999. I think the reason the M110 SASS is so expensive is because most of these weapons Knights Armament Co. makes are going to the U.S. Army and not so much to the civilian market. Not only that it's suppose to be a very high quality sniper rifle, it wasn't adopted by the Army and awarded one of the "Best 10 Inventions" in 2007 by the U.S. Army for nothing.

Varies by country, force and environment. It could be a bolt action (such as the M24 and M40, Sako TRG, etc.), or a semi automatic system (such as the M110, SR-25, PSG-1, etc).
