dirkmagurk, sorry you're going through this. Please keep us informed. My only experience with LMT is a Defender SBR that I purchased. It runs fine but came with a semiautomatic carrier and a carbine buffer. The carbine buffer is no big deal, but the semiautomatic carrier is a bow to the gun grabbers that I just didn't anticipate. Hopefully, yours will be fine once they tune it up.
