What’s a fluted AR-15 barrel? – A fluted barrel is a firearm barrel that typically has grooves or valleys machined down the length of a barrel. Fluted barrels are used on rifles and handguns. They are not limited to the AR-15 platform.

What’s the purpose of a fluted barrel?

Their are two main purposes for a fluted barrel. The barrel flutes provide a weight reduction relative to the material removed in the fluting process. The flutes also increase the surface area of the rifle barrel. The increased surface area improves the barrels ability to remain cool. Often fluted barrels are selected for cosmetic purposes. The cooling and weight reduction are bonuses.

Quality is imbued into these barrels from the start. Starting with top quality 416-R Stainless each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

Faxon manufactures all their barrels in Cincinnati, Ohio under ISO:9001 and AS:9100  quality certifications.

When the added velocity of a longer barrel needs to be preserved, but the desire for additional weight reduction remains, barrel fluting serves as an excellent solution to help shave away unwanted bulk. Criterion fluted AR-15 barrels are designed to ensure maximum concentricity and consistent dimensions throughout the full length of the bore. Eight flutes are machined around the circumference of the barrel to the front and rear of the gas port. Each flute is polished to smooth jagged edges while retaining a sharp appearance.  Each 416R stainless steel barrel comes complete with an M4 barrel extension and a .223 Wylde chamber designed to accept both .223 Remington and 5.56 NATO cartridges.

Criterion does business a little differently. Some barrels they sell factory direct while others are retailer exclusive. There is almost no competitive overlap. These fluted barrels are a Brownells exclusive.

.223 Wylde

.223 Wylde is a hybrid .223/5.56 chamber designed by Bill Wylde to yield the accuracy advantages of the match .223 Remington commercial chambering but without pressure or reliability failures when using high velocity 5.56 NATO spec ammunition. The .223 Wylde achieves better accuracy by having a chamber throat that is tighter than 5.56 but will still function reliably with military 5.56 ammunition as the case dimensions are the same.
