Bingo. This is why I asked about port sizes. Please accept this as constructive criticism. Too many manufacturers are building guns for the lowest common denominator, instead of making guns based on a higher standard criteria. The standard should be based on compatibility with suppressors, full auto reliability, with "duty" ammo. Building a gun based on the idea that it should run any ammo (primarily steel) is a recipe for an overgassed consumer grade rifle.
Now, with that being said, if your customer was running a standard carbine buffer, his gun was simply not set up correctly for suppressed shooting.
ETA: adjustable gas blocks are the current rage. But it is my opinion that if you need one to get reliable function, then it's a barrel / gas port problem and all you're doing is putting a band aid on the issue. Build the gun correctly, so it isn't needed in the first place.
Constructive criticism always welcomed. Buffer was stock.
We did not make our adjustable gas blocks for our own rifles out of a need to compensate. We made them for a traveling hunter crowd facing elevation issues and other factors. We are absolutely reaching for a higher standard in all that we do. I will address Wallace's excellent (earlier) question when I have time, probably tomorrow. I will cover some things in my answer to him that should lend some insight into our values, mission, and the quality and value that are inherent in our rifles etc.
