Tory socc pdw - Troy SOCC Low Profile BattleRail M-LOK PDW 7.6 Inch

I ordered a Troy SOCC 7.6 inches low profile Handguard. It took over 3 months to come in. When it finally arived I got it install by a certified gunsmith. That’s when I found out that THE RAIL IS OFF CENTER! I tried everything to get it centered, But everything I do ends up with the same result. The gap between the upper receiver and the Handguard is about 1/8 of an inch wide. The rail itself pulls to the left. This product was on backorder and I suspect that Troy was trying to rush their production to meet demand and as a result Quality control suffered. The barrelnut is mil-spec for Troy and the upper receiver is from Aero Precision M4E1 strip upper. And the barrel is from CMMG in 9mm 8 inches long.
