Faxon Firearms Duty Series 18" Gunner 5.56 NATO AR-15 Barrel, QPQ Nitride, 15A58R18NGQ

Product Description

The Faxon Firearms Duty Series Gunner 18" 5.56 NATO barrel is built to deliver a highly balanced AR-15/AR-15 pattern setup by blending the durability of a Government contour with the weight savings and handling of a Pencil profile. Machined from 4150 CMV steel and finished with a corrosion-resistant QPQ black nitride inside and out, this button-rifled barrel is stress relieved, air-gauge tested, and finished with an 11-degree target crown to help maximize accuracy. A rifle-length gas system and M4 barrel extension make it a strong choice for precision-focused builds, competition rifles, training, and hunting.
