I've never owned a NEF rifle but have sold many of them. Before retiring back to Canada I worked at a Wal*Mart Sporting Goods department at a store in Laurel, Md. I'm surprised at how many were repeat sales to buyers that already had one or more NEFs. Most of the buyers were quite happy with the accuracy. My only reservation was the weight of the heavy barrel model. Boy, it was a brute, but you never get it all in a single rifle. Best wishes.
