Bravo to you! I have been contemplating doing the same thing however I am using the front sight with a peep rear and have been looking for a front sight that will fit on the end. By looking at your photos it appears that the front sight from an AT44 will slide in place as the space looks the same(except for the knurling). Thanks for the photos! I will have to give this a try as I have already emptied the "can".
Hey Jnagy,There are a number of aftermarket muzzle brakes made of aluminum that mount using two allen screws.I bought one in March for about $50 bucks. Kind of expensive, very strong, looks great and fits Hatsan barrel perfectly (not a noise suppressor). Used it on my Hatsan 135.Sorry I can't be more specific about the manufacturer (TPA or something).........
