Review on KIARUO Replacement Mandrel 8，Rivet Pneumatic by Lamar Marshall

Order a pistol with spikes and order an extra set of spikes as I break them in the process. Everything was good. I order a different set of mandrels and the collar of the mandrel is shorter. See illustration. The one on the left is the first set that came with the rivet gun. The right ones are the ones I just got. You can see the difference in the length of the collars. The thorn on the left is broken. But the problem is in the collar. It's not long enough. I check the SKU on the first package I received and it matches the SKU on the second package. I am ordering a third replacement set. The same thing. This is me?
