David, LOL. 😊
I also have the IPSCO kit installed on 2511 and just like you, my first casual glance at the photos told me it was an IPSCO kit. I only caught my error earlier today.
seeing the installation was not stock and being aware of only one aftermarket conversion, I immediately assumed it must be the IPSCO kit.
and yes, I know very well what happens when one makes an assumption 😉 😕😕
