I've been looking for a Steyr Prohunter carbine in .308 with a 20" barrel. A dealer advises that Steyr now lists these features on a model called the "Mountain Rifle". Unfortunately, neither he nor his distributor have pictures or other details. I'm hoping that a reader attended the Shot Show and picked up a 1999 Steyr brochure that identifies this offering. Can anyone shed more light on this model? TIA
