The Geissele Super HBAR MOD1 14.5" Complete Upper in Distressed Diamond Cut (DDC) is a premium heavy‑barrel AR‑15 upper assembly engineered for rugged durability, heat management, and sustained accuracy. Built around a cold hammer forged, chrome‑lined 14.5‑inch barrel with an .812″ gas journal and 1:7 twist, it’s designed to handle extended precision use with minimal barrel whip. The mid‑length gas system with Super Compact gas block enhances smooth cycling, and the MK16 M‑LOK free‑float rail provides a rigid platform for optics and accessories. With a DDC finish and full Picatinny rail surfaces, this upper is optics‑ready and compatible with any AR‑15 lower. Sold with a BCG and charging handle, the 08‑616S offers core components for a robust custom rifle build centered on reliability and modularity.
