I would see that happening.
The Vang part has a wadcutter type front edge, which in a mag tube with no seams means it scrapes crap out of the tube and dumps it out the loading port. I've seen that part work with dirt, sand and shot buffer where other followers jam up. That it also has a doughnut hole in the middle means crap can also shake out of the gun rather easily, if one holds the gun muzzle up and gives it a shake.
