Yes you will snap cast iron with a sever blow from a BFH. That was the only way to demo a cast iron tube for removal. Safety glasses were a must as the porcelain shatter's like glass. That was a real PITA.
Deals can be found on Gunbroker if you look hard enough. They give you an opportunity to contact seller to ask questions. Just my 2 mags. I have dealt with them and it was a good experience.
Welcome from Indiana brother and THANK YOU for your service. I had a similar problem with my Aero M5 and realized that if I pushed the trigger forward a touch it reset.

I got this pack from these guys http://www.eagleindustries.com/products/products.aspx?id=1 found them on the back of Natchez catalogue. Used them for work and they have taken a good beating, plenty of mole and internal pockets.
