Files are sailing, MP5 22lr Safe-Semi-Semi 3 Position Safety Mod by **Awesome 22lr Fun (**HKCollector

some minor fitting required depends on print setting. I didn't have time to write up a full instruction for this, but I think the picture provided should be sufficient for anyone to follow. If there are still questions, please comment below.

The Trigger Safety piece can be modify to limit pre-travel and over-travel. I haven't explore this direction yet. it's should a pretty easy modification.

The next step on the project timeline is to have the safety ring interact with the FRT DROP IN piece to maintain a SEMI ONLY mode.

Even thou this mod is compatible with the FRT DROP IN, but there are still many issues needed to be resolved for a safe FRT Experience. OOB will inevitable happen with the current setup, personally I think the extractor contributes to the OOBs.
