Well - looking at the pics, it appears the edges of the slot where the bolt head is removed have been buggered.
UK Armours will condemn and action because of the broken edges. They felt the 1* design was inferior. When the slot broke was impossible to repair so condemned or DP service.
The issue is when you cycle the action fast or shoot in a battle situation, the bolt head can come out of the stot and be accidentally pulled out of the action.
