Ruger impact max 22 cal help

I have a Ruger impact 22 cal it fell over and broke the front sight end off now it to loud is their a part I can buy to quieten it back down I have removed the part from. End of barrel which was a job in itself that little set screw seem to hold nothing on anyway is their a muzzle break or something I can buy to put back on it or does anyone know the size of the barrel beemans sell a silencer for a 22 cal but I do not know if it will work.
 
Tennessee, measure the end of the barrel and post the size for us. Many of us have parts and pieces laying around but need that information to complete the search. Use a caliper or Micrometer and lets see what we can find to help you out. A picture would also help. Do you also need the front sight or are you using a scope? By providing enough information you will get better answers faster. Welcome to AGN!
