The Noveske Infidel is one of those barrels that earns its reputation the second you shoulder a rifle built around it. Cut from 416R stainless steel and finished with a clean bead-blasted satin, this 13.7" barrel runs a mid-length gas system and the improved polygonal rifling Noveske is known for. That rifling gives you a slight bump in velocity and slows down throat erosion, so the accuracy you get out of the gate sticks around a lot longer than a standard cut-rifled barrel.
At the heart of it is Noveske's exclusive 5.56 Match chamber, hand-polished and designed to shoot both 5.56 NATO and .223 Remington without drama. The 1:7 twist rate stabilizes everything from lighter 55-grain loads up through the heavier 77-grain match bullets, so you're not boxed into a single ammo diet. Every barrel is individually serialized and ships with a gas tube matched to its gas system, which takes some of the guesswork out of your build.
The medium contour is the sweet spot here. It keeps the weight reasonable at around 30 ounces while holding onto enough mass under the handguard to stay rigid and shoot consistently through a string. The 13.7" length gets you velocity that lands close to a 14.5" M4 profile, and it's a popular pick for folks pinning a muzzle device to reach that 16" mark for a lightweight, nimble build.
A couple of things worth knowing before you order. The barrel ships with the pinned .750" low-profile gas block already installed, and it's built for Noveske's own 1" gas block. A standard front sight base runs 1.9" and will not clear, so plan your gas block and handguard accordingly. Muzzle threads are the standard 1/2×28, giving you plenty of options for flash hiders, brakes, or a suppressor. As always with a barrel swap, having a qualified gunsmith handle the install is the smart move.
The 1:7 twist rate is built to stabilize a wide range of projectile weights, from common 55-grain FMJ up through heavier 62 and 77-grain match loads. The Noveske Match chamber is designed to run both 5.56 NATO and .223 Remington reliably. If you want to see what this barrel can really do, feed it quality match ammo in the 69 to 77-grain range.
Yes. It ships with the .750" low-profile gas block already pinned and installed, along with a gas tube matched to its mid-length gas system. Keep in mind it's designed for Noveske's own 1" gas block, and a standard front sight base at 1.9" will not fit.
The 13.7" length delivers velocity that lands very close to a 14.5" M4 profile while trimming a little length and weight for handier, more maneuverable builds. It's a common choice for pinning a muzzle device to reach 16". You get most of the ballistic performance of a longer barrel in a more compact package.
The barrel arrives with the gas block installed, but completing the assembly onto your upper involves proper headspacing and torque. A qualified gunsmith is the recommended route to make sure everything is squared away correctly. Doing it right protects both the barrel and your investment.
