There is absolutely nothing wrong with the 5.56 in CQB style engagements all the way out to 250m as long you are using the proper Ammo. It can be very effective in the hands of a trained marksman. The Marine Corps just bought a bunch of M27 iar made by Hk which is a piston driven weapon rather than a direct impengment style like the original Stoner design. The piston runs cleaner and cooler when shooting suppressed and is a hell of a weapon (Hk416 variant).

they should have just licensed the Adams arms piston conversion kit. My piston ar is the tits, so easy to clean
