All good points. I'd add that the emergence of mid-length gas systems on the DI guns has made a difference in heat and parts wear on the BCG, in addition to softening the recoil impulse even more. Additionally, it's a mature system with a wide variety of parts and accessories readily available. The SCAR may get there, but DoD dropping the Mark 16 hasn't helped the penetration into the civilian market. With Iraq winding down and given the cost of the system, it's not clear to me where the SCAR project is heading. I'd be leery about buying into a less-than-widespread weapon system.
