The Anschutz F27A Benchrest model is not common. There wouldn't be many in Canada, perhaps only the one originally brought in by Nordic some half-dozen or so years ago.
It has a single shot Fortner action with an inline BR stock meant to be shot free recoil, which means the rifle isn't touched except for the trigger. (Note in the picture below there is no butt plate of any kind.) The inline Anschutz BR stocks are available for other Anschutz match barreled actions. The barrel was available in the standard lengths for Anschutz Match 54 models, 66cm and 69cm.
The only advantage in this model over other Anschutz BR models might be its uniqueness -- a single shot Fortner action BR rifle.
