Unfortunately, it appears not. This from the article that I posted above:
"Each rifle is hand-built by precision weapons repairmen at Weapons Training Battalion in Quantico, Va., according to the according to Staff Sgt. James Knight, a sniper section repairman at Weapons Training Battalion, Quantico, Va. Beir added the old rifles are being sent back to Quantico for disassembly."
HOWEVER,
There are lots of nice sniper rifles available to civilians, including the Barrett, a version of which is also being used by our armed forces in Iraq, Afghanistan and elsewhere, and actually has a much greater effective range thanks to it's use of the .50 cal cartridge. You can learn more about the Barrett rifles here:
