The Faxon Duty Series 10.5" Gunner 300 BLK barrel combines exceptional balance and durability for short, versatile builds. Our Gunner profile merges the robustness of a Gov’t contour with the lightweight maneuverability of a Pencil profile—ideal for CQB, suppressed, or compact rifle setups.
Machined from 4150 CMV steel and button rifled with a 1:8 twist, each barrel is fully stress relieved and treated with salt bath nitride inside and out for superior corrosion resistance and long service life. Every Faxon barrel is air-gauge tested, MPI inspected, and headspace checked for reliability and accuracy straight out of the box.
