Not everybody will remember Remington VTR. They had the triangular barrel with the ported slot at the end. Didn't make him but into a three calibers or chamberings. I don't know if they didn't shoot very well or just not very popular . I haven't seen one for a long time not even one for sale used at the gunshow anywhere that got collectable? Work out really good and people keep them or what or maybe everybody strip them and just use the actions.
