Now that the season is winding down I'm getting rid of my TRG/SOS and converting to the conventional rod and slide and lower STS. The only problem that I have is that I have one of the earlier 2011 models that doesn't have the lower hole oposite of the Quick lock stabilizer mount. I'm not a big fan of the front mounted string supressors and would prefer that the STS be threaded directly into the riser from the rear. So the question is, Has anyone attempted to drill and thread the hole themselves? Or should I just accept the fact that I have to mount one from the front.
