I PM'd him. It's a smok Squid modded to bottom feed.
Just replied to your last PM. Yup it's a Squid that I modded for bottom feed. But as the others said & as I mentioned in the PM, it's no RM2. I highly recommend the RM2, it really is one of the best. I can get that Squid/ERA style attie to work great but it's not nearly as easy or forgiving as the RM2. I only use it on my Mini 2.1 for that stealth look.
Here's what your Grand would look like with a RM2 on it (second from the left)
And here's how I mod these type of atties for BF.
Again, I highly recommend to just go with a RM2.
