Red snappers are usable for any long arm. I used a set on my Gammill,and when I sold it, I tranferred them to my Innova. I LOVE Them! You might try posting on the APQS forum. I have had good luck there and I don't own an APQS! I consider my Red Snappers one of the best things I added on. I used to stick myself loading AND smoothing fabric as I rolled. No more!
