I have and AR15 with a 18" barrel, that I screw directly on a 6" 6.5 mm suppressor. Do people usually gain velocity with the can on over the opposite. I am shooting 23gr IMR 8208 XBR powder behind a Sierra 69 TMK getting about 2700fps without the can, but my magneto speed doesn't fit on the barrel with the can. Accuracy is very good.
