Hodge Defense 14.5″ 5.56mm AR-15/M4 barrel is the barrel being used on the Hodge AU Mod 2 rifles. Utilizing FN’s proprietary steel and technology, these barrels were designed to Jim Hodge’s demanding specifications and optimized for the military’s M855A1 EPR ammunition which is much more demanding on barrels.  M855A1 rounds operate at about 62,000 PSI (over 55k from M855) and are designed to perform to an expected standard of terminal performance and barrier penetration over a broader range of engagement distances; whereas previous ammunition was being criticized for being unstable and not providing consistent performance outside of a narrower optimal range.

The AU Mod 2 has been optimized for running M855A1 EPR, and this barrel is at the heart of that system.

Note:  this barrel is designed for hot 5.56 NATO and suppressor use:  We advise you use standard power springs and lighter buffers than normal MIL-SPEC barrels
