vertical ASA screw size/available?

[veteranmag]

I installed an foregrip extender on my minimag, using the screw (that previously held the vertical ASA to the rail) to connect the extender to the rail. Now, I need another screw (the same size) to connect the ASA to the extender.

Does anyone know where I can buy a screw? Or know the size of the screw (I would think it is commercially available outside the paintball world)? Thanks everyone.

it's a 1/4x20 stove head. Not easy to find. Send me your name and address and I'll send you one. tunaman5@verizon.net
