Of course they are aware of it. It's part of the design. The gap is there because these are production parts for a service grade CQB rifle. The only way to eliminate the gap would be to individually machine either every brake or every muzzle.Do we think SAI would be aware, whether or not they’d care?
If someone were to hand build the perfect M14, they would cut the barrel shoulder while test fitting the gas system, to ensure the gas tightens exactly at 6 o'clock. With a Socom, you would start with a long barrel and cut it for a flush fit inside the brake.But what about a wet hand-sanding on a mirror every gas lock for a perfect fit! Surely labor is free!
