The Radian Weapons Model 1 Upper/Handguard (brand part no. R0620) pairs a billet aluminum AR-15 upper receiver with a 15.5-inch free-float M-LOK handguard in a flat dark earth finish. The billet upper includes an integrated dust cover and forward assist, and ships complete with a Radian Raptor SD ambidextrous charging handle along with the barrel nut and mounting hardware needed to build it out. At 33.45 inches overall, it gives a builder a finished upper and handguard assembly ready for a barrel and bolt carrier group of their choice. Barrel and BCG are not included, so this is meant for a shooter assembling or upgrading an AR-15 upper from a known starting point.
