Pretty standard stuff. However: I wouldn't use a flash-hider that long. In CQB you could bang that thing all to hell. If your barrel extends into that flash hider... You'd run the risk of bending it. CQB tends to be very unforgiving.
Minus the ACU tape, cantilever mount for the Aimpoint, toss on a flip up BUIS, KAC rail covers, a fresh matching coat of paint, and you got yourself a pretty looking blaster. Birdcage would look better in my opinion, too.
