Product Description
The FAXON FIREARMS Gov't/SOCOM Duty Series 10.5 inch 5.56 NATO barrel is built for compact AR-15 builds that demand durability and consistent performance. Manufactured in-house from certified 4150 CMV steel and finished inside and out with a black nitride treatment, this SOCOM-profile barrel is designed for long service life and corrosion resistance under hard use.
