Many AR-15s on the market are chambered either in 5.56 NATO or .223 Rem. However, barrels chambered in .223 Wylde incorporate the best features of both chamberings, and the Criterion Barrels .223 Wylde AR-15 barrel is the perfect choice for users looking to build an enhanced AR. Each Criterion Barrels .223 Wylde AR-15 barrel is machined from steel and treated with a salt-bath nitride finish that hardens the surface steel, wards off corrosion and enhances the service life of the barrel. The principle benefit of the .223 Wylde chambering is the ability of users to shoot bulk-priced 5.56 NATO while still being able to take advantage of the accuracy benefits of match-grade .223 Rem. rounds.

• Chambered in .223 Wylde
• Hybrid contour
• Threaded muzzle: 1/2-28 TPI
• All-black finish

Each Criterion Barrels .223 Wylde AR-15 barrel can be had in either mid-length or rifle-length gas systems, and barrel length is optimized for each gas system profile.
