to obtain an anti-material rifle in Fallout: New Vegas you have to be at least level 26 for vendors to start selling them at stores.
NCR Ranger Combat Armor
Fallout New Vegas is a role playing game.There are several powerful weapons available to find or to buy.The Sniper Rifle is one of the better weapons.
I think you mean the 'Anti-material Rifle'. It can be bought from the gun runners, south of the strip or taken from some veteran NCR rangers.

You cannot get a silencer for the assault carbine in Fallout New Vegas I'm afraid, the only guns you can get silencers for in New Vegas are the sniper rifle, the varmint rifle, 12.7mm pistol and machine gun.
You can get a sniper rifle anywhere. First, the unique one, you get that North of Cottonwood, called the "Sniper's Nest," and it's called "Gobi Scout Champion Rifle."
The anti-material rifle is like a upgraded version of the sniper rifle, but is not the unique one. I found many from dead legionarries at Hoover Dam. They can be found all across from a variety of people around the Mojave Wasteland. I think I remember finding on at Nellis AFB. The Anti-Material Rifle can also be bought by the gun runners when you are a high enough level. But a SPECIAL sniper rifle that is GOLD is the Gobi Campaign Scouting Rifle. It is found at the `Sniper`s Nest`which is just a little north east of Cottonwood Cove. But you MUST have a lockpick skill of 100 to get it as it is in a very hard locked footlocker
The Anti-Material Rifle. It's expensive. You can buy it from Gun Runners when you are roughly around level 21 There is also the Gobi Campaign Scouting Rifle which is also a sniper rifle. You must have a lock-pick skill of 100 as it is in a locked very hard footlocker at Snipers Nest which is found Northeast of Cottonwood Cove. I think it is worth it because it is a good gun, its gold, and it match's my GOLD pip-boy
You can buy it from the Gun Runners, and if they don't have it; just wait for 24 hours and check if they have it, if not again, keep repeating.
There are several. There is the Tesla-Beaton Prototype, the Mysterious Magnum, The YCS/186 gauss rifle, the Pulse gun, Euclids C-finder and many more. They are my preferable selection of weapons.
No, Only In Op Anchorage.
