I purchased the torsion locking bar trip for my original Rare Breed trigger from Militia State Armory. After installation, the trigger will not reset if there is any pressure on the trigger and I am getting hammer follow. If I just pull the bolt back with my finger off the trigger, the hammer will lock back and the trigger will reset. It feels like the hammer is not locking back when the bolt moves to the rear. Any idea what is going on? |

Is this the fix for thst wonky spring that kinked up? If so I did this about a year ago and it was so difficult. I launched one spring and haven’t seen it since. Good thing I bought two Mine runs lights out now , but it just sits in the safe. I can see if I can get a good pic of the install if you need it. Can you post yours so we can compare?

When I installed the MSA bar, the hammer pin / sleeve slipped out of the cassette. I basically had to re-assemble the pack. If this happened to you, you’ll want to ensure it was re-assembled correctly. I ended up putting duct tape along the sides of the cassette to keep the pins from sliding out. |

That angle may be enough not to lock it out. Have you pressed underneath the trigger shoe and see if it “locks in” = resets? Is it catching somewhere or need lubricant? Can you press the bar rearward with your thumb or will it not move past that angle |
