I finally got an answer from AT and then a quick response from G5. I didn't know that the practice blades don't deploy. It doesn't say it anywhere on the package or online. So with they struck shut they are smaller than a fixed blade head. I don't understand why they only send one set of practice blades with a package of broadheads.
Thanks to those that tried to help me.
