I recently bought a Mark III .22/45 which I absolutely love shooting but was interested in putting some kind of red dot on it to try and speed up my follow p shots. I polished up some of the internals, ordered a Volquartsen trigger, and the stuff to do a grip mod. M only complaint is the thin grip so I am going to put a wrap around Hogue on it. Just wondering what others have on theirs? I have seen a ton with Burris Fast Fire over at Rim Fire Centeral and some with a small Bushnell or Aimpoint micro. Also what size dot do you prefer?
