It is machined from 6061-T6 aluminum and weighs only 10.9 ounces with its barrel nut. A continuous 1913 Picatinny top rail carries iron sights, optics and accessories without extra rail sections, and M-LOK slots take Magpul-pattern attachments. JL Billet includes the proprietary barrel nut, which has a precision bore that removes play between the barrel and handguard.
