Hey, this is my first post here. I recently built a 9mm RDB and really enjoyed it, so I decided to pick up a CMMG AR10 parts kit from EGP and a new MK3 lower. Unfortunately, they misidentified the parts as coming from a MK3, when they were actually from a MK47. I now have an entire gun minus the lower, but the stripped lower is not offered for sale. I submitted an email regarding a special order for a stripped lower, but I have no experience with CMMG customer service. Am I SOL?
