Not sure which model you're referring to. I had a NEF .22lr revolver several years ago. Fixed sights, 2 1/2" barrell. The gun shot way off. Even when I manually aimed to correct, I could barely hit a pie plate at 10 yds. If your model has adjustable sights (windage & elevation) you're probably ok.
Another item I noticed is that the action felt good, until I compared it to a S & W. From my experience, I would not recommend them.
(my Italian replica Colt Navy cap-n-ball revolver is more accurate than my NEF .22lr was!) (and cheaper!) (and had a better action!)
