u/Apart-Fuel-7276

Looking for some help with my FRS. I have a psa 8inch 9mm upper on a Spike Glock mag lower, and have mil-spec trigger to go along with the Atrius FRS. For recoil I bought the Maxim Defense RDB system and wanted to make a it also compact by adding a Tactical law folder with the Anarchy Outdoors tactical folding bolt carrier extension. At first it seemed I had to watch how much pressure I was using to get it to work in the frt mode, but now it only functions in semi in both semi and frt mode. Any thoughts or ideas on what to do to get it working how I want it?
