    Abstract: A free float handguard for a firearm having a barrel includes a handguard body and a locking arrangement. The locking arrangement includes a barrel locker and a handguard locker. The barrel locker includes a first tubular locker adapted for coaxially coupling at a fixed end of the barrel, and a second tubular locker coaxially and rotatably coupled at the first tubular locker. The handguard locker has a rear portion coaxially coupled at the first tubular locker to prevent the handguard locker from being rotated therearound, and a front portion engaged with the second tubular locker to prevent the second tubular locker from being rotated around the first tubular locker, wherein a first end portion of the handguard body is coupled at the handguard locker for locking up the handguard body around the barrel in a free float manner.
