Just wanted to let you know that freak barrels do not fit in the centerfeed module and possibly the warp module. The barrel diameter is just a bit to big and it doesn't rest inside the lip of the breech. I was having some breakage problems with the freak and accuracy wasn't that great on my sfl emag. That is when I took out the breech and noticed the problem. It fits spectacular with the dye boomstick though, and accuracy is amazing with that barrel. Maybe the cocker freak backs have a bit larger diameter than most barrels. Let me know what you find out.
