I love modifying my guns. Here is my Bronze Mark IV 22/45 Lite with 5.5inch Target Barrel and 10 inch Barrel, both bought from the Bargain Bin at Volquarten.
All barrels shoot fantastically. From a bench the 10 inch has a little advantage but I see no difference between the Lite and the 5.5. I bought the 5.5 to shoot Rimfire Iron Sight for Steel Challenge. The Lite is for Rimfire Open and the 10 inch is just because I wanted it.:gun4:
