Just to update everyone on what I decided incase you were curious.
I ended up getting ATRS to make me a 18" barrel,heavy contour in .223 wylde with a rifle length gas system. I had to go to red deer for work so I stopped at ATRS on the way through Calgary and dropped my bolt off for proper headspacing. Now we just play the waiting game but it gives me time to get the rest of the build together.
