Mmmmmmmmm........ maybe someone could show us all HOW they work in relation to a butt and bolt.

Like BAR says, some of these special tools were practically useless. I saw one such, said to be designed to take the driving spring out of an M1919 bolt. Levers, caps, special sequence, pin to insert.......... When all the real Armourers and tank crews at the sharp end used was a piece of soft-wood, press down, rotate through 90 degrees and lift sharply away. End of story. As for the extractor tool for the L1A1 extractor............. All I can say is that more extractor stays have been lost through the use of that tool than anything else.

Nope, still can't work my way through the butt assembly tool!
