There are several places to get one. Depending on if you want a production rifle or a custom rifle that will change where you purchase it from. If the gun is production it will be from Korea (That's a very good thing) and usually less powerful than a custom made gun.
If you live in America you can visit http://www.pyramydair.com/ to buy one. They carry one and its called the shinsung career dragonslayer .50. They also sell other big bores which may suit your needs.
If you live in Canada you can buy it from Air Gun Source (see related link for website)
These guns are pcps. Meaning you have to fill them up with high pressure air (3000 psi)
Which requires a special handpump or Scuba tank.
Custom guns can be purchased from a few custom manufactures.

The above answer pertains only to air rifles, which the question is not limited to.
.50 caliber rifles (gun powder) are commercially available firearms and are purchased just like any rifle such as a .30-06 hunting rifle. Best place to go is a gun store.
Yes, I can. A Barrett M107 is a .50 caliber sniper rifle.
50 caliber
Yes
Any bullet that has a diameter of one half inch is a .50 caliber bullet. There are different .50 caliber bullets- my Hawken muzzle loading rifle shoots a .50 caliber lead bullet, but different from the .50 Browning Machine Gun (that is also used in the .50 Barret sniper rifle)
how far does a 50 caliber sniper rifle shoot accuratly
Over a mile.
In the States, a 50 caliber rifle can be acquired after filing certain tax stamps. Once the tax stamps are paid and a background check has been cleared, then a 50 caliber rifle can be purchased at some specialty gun stores.
No. An Intervention shoots a smaller caliber bullet. The Barret is the rifle that shoots 50 caliber bullets. The Intervention fires .408Caliber Rounds (Bolt action)
Depends on the application. If you mean power, the higher the caliber, the more powerful it is. for example, a .22 caliber rifle is much less powerful than a .50 caliber rifle.
