Have become very interested in Sako rifles. Everyone was so helpful with my first question here that I thought I would have another. Have the opportunity to purchase a Coltsman L579 .308 for $450. Barrel and action in excellent shape with original peep and front sight hood. Stock has several pellet sized dings but in otherwise good shape. How common is this rifle and is it very collectible? Is that a good price? Thanks in advance for the help.
