Looking to sell or trade my KAC M4 RAS. It comes with three KAC rail cover panels and it's in excellent condition. It was mounted on a Colt 6920, but was used little and babied. Asking $150 OBO or trade for a 13" or 15" free float M-LOK handguard. This is cross listed. I'm located in the Summerlin area of Las Vegas.
