Best ldc for airforce condor

I have the Talon Tunes moderator on my .22 cal. Condor SS and it is very quiet. The problem is the tiny set screw that holds it in place comes loose all the time and then you get clipping and the pellet hits a foot or more away from the point of aim. I am reluctant to torque it down too hard to avoid stripping the threads. I have thought about tapping it for a larger set screw to increase the holding force and make for a stronger connection. I also have a Talon SS which I replaced the 12" barrel with a 18" barrel and bought the R&L shroud to quiet the report. The R&L shroud does a very poor job to me in comparison to the Talon Tunes moderator but has a better connection factor. I would suggest looking at DonnyFL adaptor for the Condor which provides a 1/4" 20 thread which will allow you to buy his moderator and move it to other rifles easily. I don't know if it will hold any better but at least your won't have a moderator that in made for use on just one rifle. Bill
