Good morning - I inherited this rifle and while I love all my firearms I have never been into 7.62x39. As my only AK my understand is this is a fairly pricey one and more valuable not shooting it more. The rifle holds no sentimental value so thinking of parting with it to fund items I would use / enjoy. It has original furniture plus Zentico forearm. I am having a hard time finding one in this configuration with the longer barrel. What kind of value are we looking at. Thank you.
