Fortis Manufacturing REV II Free Float Rail 13.8" M-LOK – AR-15 Platform

The Fortis REV II 13.8" free float handguard delivers improved accuracy and reduced barrel harmonics for AR-15 platform rifles. The continuous top rail and M-LOK slots at 3, 6, and 9 o'clock positions provide flexible accessory mounting while keeping weight down and barrel heat manageable during extended shooting sessions.

Machined from 6061-T6 aluminum with a Type III hard-coat anodized finish, this rail installs using a proprietary barrel nut system compatible with standard AR-15 upper receivers. The extended length accommodates longer gas systems and provides increased real estate for forward grip placement or bipod mounting. M-LOK attachment points allow quick reconfiguration without permanent modifications.
