I've only ordered a few parts from them but they have a good rep. I would not be afraid to buy from them. I'd probably buy from them before I'd buy a Bushmaster or a DPMS, and I don't have a problem with DPMS, they and Bushmaster tend to use schit for barrels on all but their high end guns, IME. The Bushie Varmints shoot, and the DPMS SASS's shoot, everything else, not so well. As far as any of these name-brand guns breaking, I've just not seen it. What you will see is guns shipped with maybe a buffer that is too light, or is under or overgassed due to the wrong size gas port hole. This is why myself and others tell people to learn to assemble their own uppers. Buy a complete lower, you can often get a complete lower for not that much more than the parts.
