So everywhere I look I see all the rifles in PRS completely customed out. Nothing factory about them. But, I am interested in getting into matches. But all I have is my Sako TRG 22 in 6.5 CM. Can this rifle be used? I noticed somewhere it states that in the factory rifle class, any rifle cannot exceed a store retail value of 2500.00. I'm outta luck in that case. Where would my rifle stand in PRS? Or do I HAVE to put some aftermarket on it to proceed? Or maybe I'm comprehending the whole picture wrongly.
