I've got all the machines needed to give it a run making a self designed m14 chassis. In fact, I completed my blueprints in 2007. Just can't be bothered with it. Way better money doing custom work with those machines. I have a very modern and fully set up composites molding shop as well and there again, even tho I have all the molds of my designs (that I've made before and some new ones) , I make WAY better money running small part runs for custom orders that are non firearm related VS making custom rifle stocks.
I would go out on a limb and say that a great many shops that can make the odd chassis or rifle stock in composite or aluminum are instead doing other work because it's far more profitable and more importantly "predictable"
I'd agree though, the Xander stocks are some of the nicest machined aluminum stocks I've laid eyes on, it is truly too bad they are not available.
