This is a Colt Sporter M4 Carbine manufactured by the company BEFORE it was sold. A perfect battle rifle with added vertical grip light. Authenticity can be verified on Colt's website through the serial number. Priced to sell so the figure is firm. I can meet you at the range I go to located at 3915 S Sam Houston Pkwy E, Houston, TX 77047. Text only at 832-786-1177. You must have a Texas driver's license or an LTC, and you must sign a Bill of Sale which I will provide.
