A good machinist, in the US, using a lathe and a mill, along with the proper jigs, fixtures, and tooling, can make every part, except a rifled barrel, but rifling and gun boring machines such as the old Pratt & Whitney ones come up for sale. The problem is the design, and selecting the proper steel or aluminum to use in the construction. For this, a thorough understanding of chamber pressures, steel or aluminum tensile strength, and safety factors are a must. Also, knowing what twist, for what ammo, is another subject when designing a good barrel. Then, this is all brought together in a proper breech locking system, that is designed to safely work, and last. Last, it must fit a shooter, and be designed so they can sight and use it.
