The DSG DSG-4101-0004 enhanced bolt carrier is designed to reduce carrier tilt/cant during recoil and increasing reliability by relocating key bearing surfaces. The enhanced carrier has fewer points of contact resulting in less friction area and the slight increase in carrier mass extends dwell time and ensures proper gas pressures. This helps for improved extraction when shooting suppressed or SBRs.
