From your pic it looks too big in OD (outside diameter) to fit in the NQD housing. If it will fit in the housing, the bore in the coupler can be reduced in the way Fire told you. Chi and I have been working with someone in England on a shock-absorbing coupler sized for the NQD. Am expecting a prototype to test very soon. Will report to the thread asap. Meanwhile, if your chinese coupler won't fit, play with your Blackjack, or get a solid coupler from Steve at SicRC.
