Better looking than the stock birdcage flash hider. It adds a nice unique look to the gun.
But I get you about the length and balance of the gun. My secondary focus when building a gun is weight and size. The smaller and lighter makes gaming those long hot hours much easier
You have a gun that isn't balanced its just going to make playing more annoying. That's one reason why I added the Silencer on my KAC PDW give it a bit more balance.
