TSPROF extended guide rod for Pioneer, Blitz, Kadet

The rod did not initially fit my Blitz Pro hinge unit/swivel as the diameter at the end of the rod was fractionally larger than the hole. The end of the rod needed sanding and the edge chamfered before being able to use. Contacted customer support, they were helpful after initially doubting my experience, as apparently this was a first, as it normally fits.
Good once able to use. 3 stars due to my experience and the frustration of not being able to immediately use.
