I have a cracked hinge pin on a 180b and a couple of prohib 18/180's I can no longer shoot. The alum receivers would cure all my problems. I fully agree, stamped receivers have nothing to do with the quality of the rifle, but unfortunately no one makes a stamped 180b replacement. The polymer 180b is simply not durable enough for the original design of the 180.
Stormwerkz has a fix for your cracked hinge lower. They ship and provide tracking. Or you could just wait for NEA and see if they sell the lowers to get you shooting the 180s again.
There is definitely a market for this....could easily be one of the first NR AR style rifle one would buy.
