AICS spigot

[Kosmic]

I have a Roedale RCSII and I'm starting to wonder if a spigot made for the AICS will fit. There's a cut-out on many spigot made for the AICS. I'm sure it will fit but will it be solid? Thanks for your help.

Accu-shot BT19 spigot (w/ cut-out)

Big Dog Steel spigot (w/ cut-out)

AICS front (w/ cut-out)

Roedale RCSII front (without cut-out)

On AI's the two protrusions lock against each other as it tightens. Without that it looks like it will just spin.

You might want to email them and ask what system they designed their spigot to work with.
