This Lower is a polymer lower. And is selling as is. It's bare and has no Internals. But it's also got a cracked/broken buffer thread where the buffer tube goes. Was selling as a project for someone if they wanna try and fix it. Person before did some repair work but not the best. I just don't have the time. So selling as is and asking $30 firm. If Interested must meet in southtown to pick up. Cash money only.
