I took my Thunderbeast suppressor off of my 300 blackout rifle and wanted to try it on my DPMS Panther. It is a full length bull barrel rifle and when I use the can on it, it wants to stovepipe the new round going in or even catch the empty on occasion. Model LR-308. Do you know if the buffer needs to be changed out for suppressed shooting? It has worked flawlessly before with the standard muzzle brake on it.
