This updated version of the VEX Tubular Free Floating Handguard increases the number of cooling slots, and modifies them so that they can now accept M-LOK accessory mounting. Suitable for 20” Bbl. or longer rifles, this 6061 machined aluminum assembly helps dissipate barrel heat and provides a solid grip with its knurled and grooved mid-section. The tube threads onto the supplied barrel nut which turns onto the Upper Receiver and is drilled to receive the gas tube (installation requires removal of your existing barrel nut). A rear knurled locking ring allows for final tube rotation so the supplied sling swivel/bipod stud will be correctly positioned. All parts are finished in hard black anodize. Complete assembly weight is 13 oz. and overall length is 12.5” long. Made in the USA.
