Adding to their extremely successful line of stripped M4A1 uppers, Daniel Defense now has the stripped M4A1 upper with their RIII rail! This stripped M4A1 AR15 style Upper Receiver Group is built around a 14.5 inch Cold Hammer Forged M4 Profile barrel and a mid-length gas system. It features a 12.5 inch lightweight RIS III rail—modeled after the revolutionary RIS II two-piece handguard developed for SOCOM—features M-LOK attachment for lighter weight while still offering M203 grenade-launcher attachment.
