The custom building business is not going away. It is going to have its highs and lows, but it will remain. The Kibler guns are a different product than what the big money customers want. If Mr Kibler were to build a rifle identical to one of his kits, but built it from a blank with no computer tools, he could sell it for far more than he could get for one of his kits. Single action revolvers will typically cost about $300 extra if you get one engraved by a computer machine. Get one engraved by hand and it will easily be an extra $10,000. Holland & Holland will often add on well over $100,000 extra to the price. And they have a waiting list also. People are willing pay for the craftsmanship. Anything custom made has a value above machine or assembly line made.
Custom muzzleloaders are dirt cheap. Hard to imagine that anyone would make one for $3000 to $5000. If I were to build one for a customer, which I won't, price would start at about $25,000 to $30,000, because for any less than that, I would make more money at my job in the time it would take me to build a gun. And prices would go up as soon as I had more than one job on the waiting list.
Then there is all the anger at the price of custom and even production guns. Its pricing people out of the hobby. Well, the custom yacht that I want to get will cost about $30 million and then there is a couple million dollars more in annual operating expense. It is putting a serious dent in my yachting hobby. So I decided Formula 1 race cars would be a fun hobby. But I got priced out of that also. Not very happy about it. Finally I decided to face reality and find a hobby that I can afford. Very large numbers of people cannot afford to do the fun things that they would like to. That is just the real world. You either find a way to afford it or you find something else to do.
The Kibler kits have brought getting a fine rifle within the reach of a lot more people. But there are still plenty of people out there willing to pay $10,000+ for a one of a kind hand made gun. I think the Kibler kits have knocked a lot of the mediocre builders out of the market. But it is not going to have any effect on the high end builders.
