There are already several sources/outfits that make the muzzle bearing. It has to be aligned and welded into the front of the demilled barrel shroud section of the receiver. They have even been offered as a "group buy" over on "Weaponeer". The CAM section alone isn't worth making (in my opinion). If you are going to stamp it out, then make the entire rear section of the receiver.dagobert wrote::idea: Now here's an alternative that MIGHT be cheaper and easier to make happen- why not see if you can get the cam sections (and maybe nose pieces? ) sub-contracted out and see if bringing that section to market might be any cheaper? It may still be cost prohibitive; I don't claim to know the details of stamping and die-making business. But it might be a good compromise on a part that is not readily available and the money out of that might be usable to bootstrap up the complete stampings.
Now, question I have for you regarding the "business" aspect of this. If you have $50k-$75K to invest and know you won't see any return for about a year, would you spend it on this project? Is there something that is less risky and offers a higher yield potential? I only ask this because several times I have run into folks who are just getting started with the retail side of the "firearm industry" and they are shocked at the minimal profit margin and short return on the investment.
To me these are things to consider if you are working up a "business plan" and seeking an investor to get behind this manufacturing project.
