AM/MM VA ASA screw?

[ß?µ£ §mµ®ƒ]

Anyone know what size the screw is that holds the VA ASA to the AM/MM rail? I cant find one for the life of me on Tunamart, themagsmith, or airgun's website. Im pretty sure its 1/4-20 by 1/2 but its no where to be found. Is that the rightsize? I may have to go to the hardware store.
