AR-15 4 Rail Free Float Tube - Carbine Length

AR-15 4 Rail Free Float Tube - Carbine Length

Our new and improved version of the 4 rail free float tube. Featuring a solid one-piece free float tube made from 6000 series aluminum with a T6 heat treatment. The Picatinny style rails are integrally machined into the free float tube. This is compared to having the rails bolted on. The Picatinny rails are designed for the attachment of foregrips, flashlights, optics or any other type of rail mounted accessories. The free float tube is also vented for increased airflow to the barrel. The overall width dimension is 2 3/8", giving it the same feel as an AP4 handguard.
