The story of my overgassed DD MK18 & DD CS

**Dcr5595** · 08-07-17, 16:15

Daniel defense called today asking if I'd like to do an RMA so we will see what happens. No matter what the outcome they have been good from a warranty perspective the few times I have had issues.

Sent in my upper as well. Guess we'll wait and see how they handle it from here.

Maybe if I keep complaining to their CS about gas ports they fix all their other overgassed barrels.

I just heard that I did get a new barrel and my upper will be back tomorrow. The service rep did say that they are fielding a lot of requests of a similar nature right now.

Things like this are why I'll always buy from the nice, higher end manufacturers.

Is there a serial number range to look for? How can we tell when the gun was made?

Not sure this helps you but my upper was assembled by them in Q1 2013.

Recently received a few barrels. Can't find my pin gauges at the moment but my 9/128 drill bit doesn't fit. It may with slight pressure but not going to press anything into the port. Going to say between .069 and .070 on these two. I'm ok with that!!
