The story of my overgassed DD MK18 & DD CS

[Glass04]

After several delays, both in getting my RMA number, then on my part - having a 16 month old, busy work schedule, and a UPS facility that appartly works bankers' hours, and finally the temporary closure of DD due to the hurricane I can say that mk18 upper will be heading back to me tomorrow!

Spoke with a very helpful CS rep who looked up my ticket and let me know that the barrel was replaced along with a new gas block and new bolt carrier as well. When I asked why the bolt carrier he said that it was most likely due to the armorer's finding a gas leak.

I was also informed that the new barrel has the smaller .070 gas port.

Can't wait to get the upper back and see how it compares to my SIONICS 11.5 RGP setup with the revised porting.

Did they go with exact .070"? I saw they mentioned .072" recently.

I was quoted .071 from CS, but I haven't measured yet. Trying to get some time to pull off the gas block after I grab a set of pin gauges from a friend. I'll post up to verify.

This makes me feel a little better about my recent purchase but I will call customer service to verify.
