KAC Mag release button from Ambi release

[js213]

I'm looking for a KAC mag release button from their ambi mag release

(This one)
24895

I don't need the "ambi" part, just the button/set screw/plastic part for the right side of the gun. I really like the feel of these buttons.

I would be willing to buy the entire thing of the price is right.

Thanks,
Jeff
