Not that its a big deal but that gun is Gen 2,,,,thats why the cheaper price. Brownells has the Gen 2 6mm Creedmoor for 960. Gen 1 has a keymod handrail with 2 screws,,,barrel doesnt go perfectly down the center of the rail. Gen 2 is a 4 screw keymod handrail, barrel is centered perfectly. Gen 3 is a M-Lok handrail.
