I installed it following the youtube video. It only shoots in the semi mode, whether in semi or binary. Has anyone installed it and can you help me fix the problem?
I believe only the Fostech Echo requires the full auto bolt carrier. I have the BFSIII w/o a full auto bolt carrier and it functions fine. Did you go through the detailed dry fire checklist provided by Franklin?
