Wilson Combat is thrilled to offer a new line of modular M-LOK free float hand guards for the AR-15 platform. The M-LOK AR hand guard system has been designed in order to be the lightest yet strongest most versatile free float hand guard system on the market today.Machined on a 5-zxis CNC machine from high strength 6005A-T5 aircraft aluminum with a mil-spec hard coat anodized finish the hand guard will looks as good as it performs. An oversized and tough 4130 steel barrel nut attachment reduces heat transfer and allows for the installation of the sleek comfortable hand guard.*Please note the barrel nut has retained the original TRIM rail system to make it simple for users to easily swap the older Wilson Combat TRIM rail design with this new M-LOK version.Features / SpecsWilson Combat TRMLOK12AR-15 Free Float Hand Guard12.6" Overall LengthFull Length Top Optics RailM-LOK Modular Attachment PointsCompatible with Most Low Profile Gas Blocks (1.47" Internal Diameter)Simple 5 Minute InstallationOverall Weight 11oz4130 Steel Proprietary Barrel NutLight Strong and Compact Free Float DesignMachined from 6005A-T5 Aluminum ExtrusionMil-Spec Hard Coat Anodized FinishMatte BlackIncludesBarrel NutInstallation ScrewsFitsMil-spec AR-15 Upper Receivers
