Brandon,
If you ever want to trade that 20" barrel for a 16" Bushmaster dissipator barrel, I'd swap you. Your hand guards would go right on it. Just putting that out there.
If you want one, Dave, now would be the time to buy one from PSA. Kinda long shipping wait but the quality is pretty decent. Just broke the 1500 round mark with the only malfunction being a weak DPMS action spring forcing me to use the forward assist to close fully close the bolt.
