Faxon Firearms AR-15 Match Series Barrel Features The Faxon Firearms AR-15 Match Series Barrel pairs a .223 Wylde chamber with 5R rifling for a hybrid rifling geometry that reduces jacket deformation compared to conventional land-and-groove rifling. This combination allows for less bullet jump and tighter accuracy potential while every barrel is individually checked for headspace using precision custom hardened gauges before leaving the factory. The barrel uses a mid-length gas system with a .750 inch gas block diameter and a 1.1 inch gas block journal length giving builders a known compatible gas system setup. A recessed 11-degree target crown protects the rifling at the muzzle and supports consistent accuracy shot after shot. Machined from 416-R stainless steel the barrel is individually MPI tested for safety before being Nitride treated inside and out which locks in the bore extends barrel life and keeps corrosive elements at bay. The flame fluted profile reduces weight on the 18 inch length while adding surface area for cooling during sustained fire. The M4 feed ramp barrel extension is coated in Nickel Teflon which maintains dry lubricity and corrosion resistance while tightening the fit between the extension and the upper receiver for improved accuracy. Threaded 1/2x28 at the muzzle the Faxon Firearms AR-15 Match Series Barrel is for sale at GrabAGun for shooters building a precision AR-15 upper.
