For goodness sakes.
Just call Brownell's, order the correct front sight, and move on with your life. :-)
You will not get any satisfaction from NEF's customer service. The Handi-Rifles being sold now are more like a "gun kit", to be worked out and rebuilt, instead of finished working rifles. It would appear to me that about 75% of all posts regarding Handi's are from folks who buy brand new ones, and then find that out of the box, they are replete with problems.
The reason that NEF keeps putting the wrong sight on the Classic is that they have a bunch of these sights in inventory, from the previous 38-55s, and they simply don't care.
