thanks fellows. I got an 18 inch rifle length gas barrel in a slim profile with the black finish from black hole weaponry. The price wasn't too bad because they were having a 20 percent off sale for shot show that they were willing to extend till today because their website crashed yesterday. That said they did charge me 26 on shipping so it still cost me quite a bit.
Now I just need to decide on a gas block and tube for this beast.
