Noveske Infidel Match Barrel AR-15 Pistol 5.56x45mm NATO Medium Contour 1 in 7" Twist 13.7" Stainless Steel with Low Profile Gas Block - SKU: 07000052 - UPC: 840906104569
Product Description
The Noveske Infidel Match Barrel (07000052) is a legendary 13.7-inch match-grade barrel kit engineered for supreme accuracy, soft recoil impulse, and duty-grade reliability in AR-15 platforms. Ideal for custom recce builds, short-barreled rifles (SBR), and 16-inch pin-and-weld rifle setups, the 13.7-inch length allows shooters to pin and weld extended muzzle devices (such as the KX3 or Dead Air KeyMo adapters) to achieve a legal 16-inch non-NFA overall length.
Precision-machined from 416R stainless steel with extended M4 feed ramps and Noveske’s proprietary 5.56 Noveske Match Chamber, this barrel features a 1-in-7" twist rate that excels at stabilizing heavy 62gr to 77gr match ammunition. The medium contour profile balances front-end weight distribution while maintaining structural heat dissipation under sustained rapid fire schedules.
The Noveske Infidel barrel utilizes a KX3/Infidel-length gas system (Infidel gas length) and includes a factory-matched low-profile gas block pinned directly to the barrel. Complete with a pre-installed gas block coil pin and gas tube, this kit delivers a complete drop-in core for high-performance upper receiver staging.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard AR-15 upper receivers. Uses a 13.7" length barrel with an Infidel-specific gas length system (included gas tube must be used). Ideal for pinning and welding appropriate length muzzle devices to reach 16" OAL.
- Verify upper receiver assembly is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Apply anti-seize grease to upper receiver barrel threads and seat barrel extension alignment pin into upper receiver slot.
- Torque barrel nut to manufacturer specification (30-80 ft-lbs).
- Slide included pinned low-profile gas block and custom-length gas tube assembly onto barrel journal and drive cross-pin securely.
- Index handguard over low-profile gas block and confirm proper barrel alignment prior to muzzle device installation.
