The Geissele Super Duty 16" Heavy Barrel (.750 Journal) black stripped upper receiver is a premium AR‑pattern upper designed as a drop‑in core for performance rifle builds. The upper mates to an MK16 Super Modular Rail via a center aligning tab to prevent rail rotation. The system is built around a manganese phosphate coated, cold hammer forged, chrome‑lined barrel with a 1:7 twist and a mid‑length gas system using a Super Compact gas block for smooth, reliable cycling. Geissele barrels are precision machined for consistent accuracy and durability. This barreled upper is finished in black anodize and follows Geissele's Super Duty specifications.
