I have owned this gun for roughly ten years and never shot it! Didn't like the factory rear sight which is just a William's WGRS peep which is not very friendly to field adjustments. Front sight is a Lyman 17A with a circle insert (only came with the single insert). Just by chance I happened across an old listing of William's FP sights which showed that at one time they made an FP type to fit the H&R rifles (which is all this model is) using the 2 rear scope mount holes in the top of the barrel just like the WGRS. Started an internet search and discovered that this sight is now either discontinued or is in permanent backorder mode, take your pick. By sheer luck, found a stocking dealer in Ontario, Canada that had two of these on the shelf with the desired TK adjustment knobs included. The wonders of the internet!!! Problem was, shipping to NH was nearly $70!!! So, making an executive decision I bought them both. Have installed the first one on the 38-55 and now, maybe I am ready to try it out. Have some Lee cast lead 250 grain bullets which are as cast about 0.379" over light loads of 4759. Will be interesting.
