Take a look at Texas Brigade Armory
. They offer many of the past Marine Corps sniper rifles.
M40A3 (current USMC sniper rifle, posted picture)
And last but definately not least, the M70, the Winchester Model 70 in 30-06 with Unertl Scope, copying the rifle made famous by Gunny Hathcock.
Another thing about Texas Brigade Armory, they offer something that I have never seen offered by any other "sniper rifle" manufactures. They guarantee 1/4 MOA at 100 yards! The best guarentee I have ever seen by any other company is 1/2 MOA.
