LWRC M61C Spartan, 5.56mm cal. auto rifle. Serial # 03-78637. New in box. Flat Dark Earth finish. 14.5" spiral fluted barrel with a pinned ACC Blackout flashider brings the barrel length to 17". State of the art piston design and the absolute best of everything - top of the line carbine. GeisseleÊ super dynamic flat trigger with a crisp pull and quick reset. Mag pul grip sights and stock. 11" aluminum free float forearm with attachment points - much more ergonomic and thinner than regular rails. A Spartan shield and helmet is etched on the right side of the receiver and "Come and Get It" is inscribed on the dustcover. Ambi -single point sling mounts and charging handle. This is the most impressive carbine I have handled. Everything is so well thought out with superior design and function. Includes box, magazine and paperwork. A top of the line carbine and being one of 300 will be a great one to put away.
