Faxon Firearms Match Series Target Barrel Features The Faxon Firearms Match Series Target barrel is machined from 416-R stainless steel and chambered in .223 Wylde a chambering that allows both .223 Rem and 5.56 NATO ammunition to be run with match grade accuracy. Its 5R button rifling uses a hybrid land and groove geometry with reduced sharp angles which cuts down on jacket deformation and improves both velocity retention and ease of cleaning. The 1 in 7 inch twist rate stabilizes a wide range of bullet weights giving shooters flexibility when selecting match ammunition. An 11 degree target crown protects the rifling at the muzzle and helps ensure consistent bullet exit for tighter groups downrange. Every barrel in the Match Series is fully stress relieved and air gauge tested before being individually MPI inspected for safety ensuring a consistent defect free bore. After machining the barrel receives a nitride treatment inside and out which locks in the bore dimensions extends barrel life and resists the elements during extended range sessions. The bead blast finish provides a clean low glare surface that complements the 1/2x28 threaded muzzle ready to accept a brake comp or suppressor. Competitive shooters and precision rifle builders looking for a dependable 20 inch barrel will find this Match Series offering a strong foundation for their next build.
