It is front heavy but the commando version is a lot lighter better feeling gun.That Sig 556 is not for me. My friend bought one about 6 months ago. He got the top-o-the-line with an EOTech 552. I'm sure some people love it, but that's just too many accessory rails, it's super heavy, and it has a couple of small things they need to change. The ejector smacks the case into the gun and scratches it all up.
