20" Precision Setup This is a semi-clone which is not 100% authentic to the military's variant, but you can get the idea from this rifle.  This particular AR sports a Larue 12.0 free floated rail, as well as Nikon Tactical 2.5x10x44 mounted in a Larue Tactical SPR 1.93 QD mount and a Leupold MR/T M3 scope mounted in a pair of ARMS #22 high rings. A very accurate, low recoil, and enjoyable weapon.  They shoot extremely well and quiet when suppressed.
