I know what you mean about the mk12. But the MK18 is decently close, aside from the furniture and DD sights. Life's too short to worry about whether a barrel is 10.3 or 10.5", what stock or grip is used, etc. Most of the guys who are actually issued a Mk18 have some flexibility on how they choose to kit up the gun anyway.
