Dye Hyper 3 Reg question

[olliewidd]

Ive got a hyper 3 reg that I need to take apart for anno but im unsure of the size of the allen key I need to undo the top part. Its the standard thread size rather than the dye thread size so the allen key is alot larger and as yet I cant seem to find one that fits. Any info would be great. Thanks

at a pinch ? you can always place a smaller one in with it, to take up the space, then turn the both of them together ?
