I ran across this very nice Sako today and I could use a bit of information. It is a Heavy Barrel L579 chambered in .243 Winchester. It has a front peep sight and what appears to be the rear peep sight mount attached to the left side of the receiver. I also think it has Sako rings mounted to the top of the receiver. Would the rear peep sight have been on the gun when it left the factory? Is there any chance I will be able to find the correct rear sight for this gun? The wood and metal are just about perfect. Any thoughts on the value will be appreciated. I paid $700 for the gun just because it looks so nice. I have no idea how I did. This is my first post here and hope it is the first of many.
