The Faxon Duty Series 16" Gunner 5.56 Barreled Upper is built for shooters who need dependable, duty-grade performance with excellent balance and handling. Centered around Faxon’s proven 16" Duty Series Gunner Barrel, this upper is ideal for training, patrol, and defensive applications where reliability matters most.
This model features a standard A2 flash hider and a Faxon low-profile fixed gas block, paired with a smooth-cycling mid-length stainless steel gas system. Up front, the 15" Faxon Streamline Aluminum M-LOK® Handguard delivers a slim, free-floated platform with plenty of room for mission-essential accessories.
Like all Faxon Firearms products, this barreled upper is machined and assembled in-house at Faxon Firearms’ Greater Cincinnati, Ohio facility and backed by the Faxon Lifetime Guarantee.
Duty-Grade AR-15 Barreled Upper Performance
The Gunner profile is designed to reduce unnecessary weight while maintaining rigidity where it counts. Combined with the mid-length gas system and fixed gas block, this setup provides consistent function across a wide range of 5.56 NATO and .223 Remington loads—without the added tuning features of suppressor-ready configurations.
