Yes, that is correct. The arrow is held in place by 3 brushes that are say....oh, I don't know.....3/16" wide...2 on top and 1 on bottom....The fletches pass in between those bristles....Well, if you shoot a hard right helical, the fletch will "twist" into the brushes...

Madjac is the first I've heard any problems with.....about a dozen guys at the shop shoot them and are very happy with them.....Not saying it's not the case though...
