I have an 18in DB grendel and havent had a single malfunction. No complaints. Only added a CMC trigger. Also got a DB in 5.56 back when they were under $400 and it has run perfect as well. Nothing bad to say about the 12in PSA upper either. A lot of theirs come with adjustable gas blocks to which is a plus if you have a silencer
