From the first link "They'll be taking 2,000 of these capable (and pre-customized by the soldiers who carried them) sniper rifles and selling them on a first-come, first-serve basis, with priority given to military snipers, active and reserve duty military, retired military, and law enforcement, respectively."
And from DefenseReview.com "Instructions for purchasing one of these M24s can be found at
www.remingtondefense.com starting in mid-January 2012. Remington will initially limit sales of these complete systems to three distinct groups prioritized in the order below:
1. Military Snipers – Any current or former U.S. military sniper. All priority purchasers must provide a photocopy of a graduation certificate from a certified U.S. military sniper school (e.g. U.S. Army Sniper School, Special Operations Target Interdiction Course, etc). This group is not required to have a current U.S. military affiliation.
2. Active Duty, National Guard, and Reserve Military Personnel – Any member of any service currently serving in the U.S. military. Must provide proof of military eligibility. Inactive Ready Reserve members are not eligible for a purchase in 2012.
