The M4V11 Upper Receiver Group from Daniel Defense is a great choice if you are building a high quality modern sporting rifle. It features a 16" Government profile barrel and the Daniel Defense SLIIM Rail 15.0. This long KeyMod free floating handguard allows the operator to place the support hand close to the muzzle for more precise control when transitioning multiple targets. Combined with the smoother recoil impulse of the mid length gas system, this allows for more precise rapid fire. The assembly is complete with bolt carrier group and charging handle.
