I took an interest in Ballistic Advantage when I saw that they had 10.3 inch barrels in 5.56. I've been trying to find a 10.3 inch barrel with the correct gas port diameter so that I can replace the barrel in my Daniel Defense MK 18 with something that isn't stupidly over-gassed.
After a couple of phone calls without producing any results but going to voicemail I sent an email to their customer service department asking if they could tell me what size of Gasport these particular barrels had. The response I received was that they would not discuss specific measurements of the gas ports on their barrels but it was "smaller than the industry average". I did send a further inquiry as to whether they would refund and accept the return of a barrel that doesn't meet the customer's specifications and whether I would have to return it after taking a 0.071" and 0.072" pin gauge to the barrel after receiving it. It's been close to two weeks with no response to that inquiry in my case.
