What you have done with your guns is irrelevant.
What I do with my firearms is in fact entirely relevent, you may wish to twist your barrels around to satisify the accuracy you wish. I will use sight adjustments, which is the correct way to accomplish the same thing.
Granted, you are entitled to your opinion regarding the R/R. but in reality Aluminum Ally is in fact nothing more that a pop metal, don't believe it, put a torch to it. Many manufactures today use aluminum alloys and ZAMAK, Henry Repeating Arms being one which is a leader in the lever action .22 industry.
Heritage has been in business for well over 10 years manufacturing their revolvers with many, satisified customers. Granted their guarantee is only for 1 year but they offer a lifetime repair for only the cost of shipping and price of parts with no bench labor or testing after being added on, even the Smith & Wesson can not equal that.
Remember, not everyone has the means to purchase the high dollar items, no matter what they may be, firearms or TV sets. We all start someplace and their folks starting a family and wish to enjoy the sport we all wish to have grow, at least I hope so, these arms are a way for them to get started and for them to enjoy the sport.
I'm sure you would not wish them to do without for a year or more doing without rather than joining in.
I'm past that point in my life at the age of 68, but I still know a value and price point within a budget when I see it.
For those that think ZAMAK is nothing but a cheap "pot metal" it would behove you to read the following links.

Also remember the following manufacture and use of Zamak castings, Cannon, Nikon, Fuji, and other fine name brand cameras. Plus many of the parts of your "whoever you may be" vehicle that you put your life and the lives of your family in are made of Zamak.
Regarding how poor a steel 12L14 is check this link

Yes there lower grade steels, worse that 12L14.
One reason 12L14 is such an inexpensive steel is its mass produced much more than many other steels which brings the price down.
Cheap and inferior are the wrong words to use, affordable is more in line with the manufacturer needs and price point, placing value in the customers hands.
Not every has the means or needs for the Land Rover, or Cadillac, but most every one does have need for personal transportation be it a Chevy or Ford or a used car.
