Things I liked:I have a 1969 Benjie 342 and the rebuild kit breathed new life into this old rifle. The instructions were good in my opinion and rebuilding this rifle was very easy and only took 15 minutes. Things I would have changed:Suggest including lead washer. The Teflon washer is too flimsy and was torn on my first try. Reused the old lead washer instead. What others should know:Definitely use the suggestion of wrapping the tool with duct tape to the size of the cylinder. This will help with aligning the packing nut. I put a screwdriver through the holes on the tool and held the barrel between my feet because of the pressure required to compress the springs.
