The Radian Weapons Model 1 Upper/Handguard (brand part no. R0641) pairs a billet aluminum AR-15 upper receiver with a 10-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 32.55 inches overall, it is sized for a shorter-barrel or SBR-length AR-15 build. Barrel and bolt carrier group are not included, so this is meant for a shooter assembling or upgrading an AR-15 upper from a known starting point.
