I would say the XM-109. 25mm sniper rifle cannon with a scope.
As far as I understand this is more of a Grenade Launcher, so not a Anti Material Rifle in the traditional sense...
I know of these Anti-Material and Special Purpose scoped rifles:
USA
M82A1/A2/A3, the most famous Anti-Material Rifle, .50BMG
XM107, Lightweight version of the Barrett
XM109, the 25mm version
Russia
OSV-98 12.7mm Anti-Material rifle
Some others have been made too but this was one of the few that was actively used.
Hungary
Gepard series, ranging from .50 NATO to 14.5mm Russian.
South Africa
NTW-20 super caliber 20mm Cannon
Ofcourse there are many more, some can be seen on:
www.world.guns.ru...
Which is the best? I'd personally go with a Barrett since it effectively reduces recoil to an acceptable level comparable to a 12ga...
