FAXON AR15 BARREL 5.56 NATO

The Faxon Duty Series 16 Gunner Profile Mid-Length 5.56 NATO Barrel is the barrel most builders should start with and for most it's the one they'll finish with. It combines the right gas system for a 16 build a profile that cuts weight without sacrificing stiffness and the steel finish and process standards that have earned Faxon multiple Gold Awards from Shooting Sports Retailer and Tactical Retailer magazines. This is a workhorse for a general-purpose carbine a training rifle a home defense build or any 16 setup where you want proven performance without overpaying for a specialty series. - The Gunner profile is Faxon's most popular contour for good reason. It blends the rigidity of a Government-style barrel with the weight savings of a Pencil tapering along the barrels length to remove mass where it isnt contributing to stiffness or heat capacity. For a 16 rifle you'll carry train with or compete with that balance is exactly right. Not sure which profile series or gas length fits your build? Faxons complete 5.56 barrel guide covers every variable use case by use case so you can make a confident call before you buy. - Mid-length gas is the right choice at 16. The port is positioned to keep pressure lower at the bolt carrier than carbine-length gas would which means a softer more linear recoil impulse less wear on the bolt and buffer system over thousands of rounds and noticeably better behavior when a suppressor is in the equation. It's a better-engineered system for this barrel length and Faxon holds the gas port location to a tight positional tolerance on the engineering drawing to ensure every barrel leaves the shop consistent. - Best for: general-purpose and home defense carbines training rifles competition builds suppressor-ready 16 setups. - Not for: builders who need mil-spec 1:7 twist for tracer compatibility (see the Combat Series) or those building a dedicated ultralight competition rifle (see Pencil profile). - Quick Specs - Cartridge: 5.56 NATO - Length: 16.125 - Profile: Gunner - Twist: 1:8 RH 6-groove - Gas System: Mid-Length - Gas Block Seat: .625 - Material: 4150 CMV - Finish: Salt-Bath Nitride (inside & out) - Extension: Black oxide M4 feed ramps - Crown: 11 target crown - Muzzle Thread: 1/2-28 - MPI: 100% wet inspected - Headspace: 100% GO/NO-GO verified - Warranty: Lifetime Guarantee - Made in: Cincinnati Ohio
