Civilian Marksmanship Program (CMP) is again accepting orders for M1 Garands. They were unavailable (sold out) for awhile, but the Army has released a 'large' quantity (rumor says 110-120,000) M1's.
Also available are M1 Carbines.
Ammunition and other items are available, also. I've shot the Greek Pyrkal HXP .30-06, and it shoots really well.
Eligibility is listed here, and it is WELL worth the effort to jump through the hoops to be eligible to purchase this surplus property.
I thoroughly enjoy my Garand. I hope the budget will stand the strain for a few more.....
