Agreed. My service rifle DPMS upper/Bushmaster lower is going on 12K rounds without a malfunction due to the rifle itself. Personal experience forbids me to lump those mfgs. into the "that kind of mfg." category. But if I'm going to be accused of discussing "that kind of trash" so be it. I'm sure not going to be run out of a forum for an honest opinion.
I'm going to keep pumping rounds out of this Del-Ton upper until it either works or it doesn't. I have been satisfied with functionality and accuracy so far.
