How did you guys get the guns to attach to the fast packs? Mine keep falling off!!!

Barrel into the latch first and then give them a good push downwards. You should feel it snap in even though you probably won't hear it.

If the gun is not transformed properly it can lead to it not seating properly. The back of the "handle" should be 90deg to the back of the gun.
