Ok, a few things here. I used the PTP Power Feed Adapter
to get the tube over to the left of the body, this is not the most compact setup but it works quite well. To get it a little tighter, I would use the AGD Power Feed Adapters that should come in the kit.

Another option would be to use the LAPCO direct feed with a power feed on that to run the hose under the gun.

Ill try to get some pictures of alternate mounting options, but I have been forgetfull of late in taking my camera to work.
