I'm trying to recall if my early Renegade's tang had three holes, I know early Hawken models did and they were for the Thompson Center tang sight. Maybe someone with an early Renegade will chime in. I have a Renegade in the 46XX range but the tang is not drilled for the T/C peep. However, I bought this gun used and it could be the stock is from a model later than the barrel. Later Hawken models did not have the third hole, nor did my PA Hunter models, Big Boar or Renegade Hunter, single trigger, models I own.
Send a photo of the tang on your Renegade, it might have been drilled after leaving the factory. I've had my Big Boar and a PA Hunter Carbine drilled, wish I wouldn't have now as both need lower front sights to get the elevation I need using the T/C tang mounted peep.
