If there was greater demand because of being non NFA, more companies would produce them and I firmly believe the prices would drop. Plus, the companies now making them have to make profits form low volume sales. If they could sell 10 times as many they could make more money with less mark up.
Lets say it cost $50 to make one for a 22. You sell 1000 for $200. 1000 x $150= $150,000. Or you sell 10,000 at $150
10,000x$100= $1,000,000.
With a good CNC setup they would be easy to produce in volume. Even a small shop with a under $100,000 machine producing enough parts to assemble an average of just 30 a day with a net of $50 per unit would keep a family well fed. The actual material cost are low, and with carbide or ceramic cutters in a coolant flooded machine the tooling cost wouldn't be bad either. Small shop space, shipping, and receiving cost would be low and payments on the machine. Say a $1500 a week. Buy the tubing bulk cut and thread the ends. Produce end caps one day and baffles the rest of the week. Hey, I might even do it. LOL
I have seriously been thinking of making a suppressor, I have the paper work, the $200 isn't really an issue but does kind of bug me, but then there is also probably the long wait of up to 6 mths. I think I am going to just wait and see how this shakes out. My BIL has a sporting goods store and stocks them. Says he would sell way more if it wasn't for the NFA hassle and he even has a setup that kicks out the paper work for a buyer.
