I have always shot 4 blade Muzzys for they either no longer make them or the local Gander Mtn. simply does not have them in so I grabbed a set of the 3 blades but am having a heck of a time assembling them. I can get 2 of the blades set in place but cannot seem to get the third into place. Is there a trick to it that I am missing or am I just a clown. Any help would be appreciated. Thanks!
