As some of you know, I am underwhelmed by the HW25 and I gave the one I had away. Apart from the sights they are really no better than a Diana 23/ Milbro 76.
There is a blind hole bored in the breech block, the spring and ball are pushed in by a rod with a three pronged spirally cylinder around it then they whack it with a hammer, crimping the mouth of the hole. That’s my guess by looking at it. Not easily rebuildable.
