Need a used 20" RAS. I'm going back to the dirt (now I'll have OEF and OIF under my belt). I'd like to put a RAS on my M16 when I go. If anybody has a 20" RAS they can spare I'm interested. Condition is not important as long as all 4 rails are good. I'm not made of money but let me know what you need for a used RAS and if it's a decent price I'll pay that plus pics of it installed on a M16 in Iraq.
