This is mostly a re-upload, though the video has changed a bit. The barrel rifling is shown at the end and there are links for the plans.
Gun designer Mark Serbu shows you how to make the GB-22, a .22 caliber pistol which has only 4 parts and can be made at home using only simple tools. Plans are now available! Click here: http://www.serbustuff.com/products/gb... The plans set shows you how to build the GB-22 with a pinned-on barrel and a 3-piece slide which is screwed together. Much easier for the home builder!
