Did you ever wonder what the gun was that Marcus Luttrell used during Operation Red Wings? It looks aesthetically very much like your standard M16 with a paint job but it’s what underneath that separates the two rifles. The SPR Marcus used was a system developed in Naval Special Warfare (NSW) and coined the Mark 12 Mod 0.
The main difference in this system besides it’s high-speed attachments like suppressors and optics is it is ‘accurized’. It uses a custom barrel that is free floated to give the weapon extra range and accuracy when used with heavier grain bullets.
