Product DescriptionThe Faxon Firearms Match Series 20" barrel is manufactured in-house from gun-barrel-quality 416-R stainless steel and chambered in .22 ARC for high-performance precision shooting. It features 5R rifling, a hybrid rifling design with reduced sharp angles to help minimize jacket deformation, promote higher velocity potential, and simplify cleaning. After rigorous testing, each barrel is individually magnetic particle inspected (MPI) for safety and is nitride treated inside and out to enhance corrosion resistance and extend barrel life. The barrel extension is coated in Nickel Teflon for excellent dry lubricity and corrosion resistance, helping promote a tight, consistent fit between the extension and receiver.Product Highlights Match Series 416-R stainless steel barrel chambered in .22 ARC for accuracy-focused builds 5R rifling helps reduce jacket deformation for consistent performance and easier cleaning Nitride treatment inside and out improves wear resistance, corrosion protection, and barrel longevity Individually magnetic particle inspected (MPI) for enhanced quality control and safety Nickel Teflon coated extension provides excellent dry lubricity and corrosion resistance for a precise fitSpecs Brand: Faxon Firearms Manufacturer Part Number: 15B22A7R20LMQ5RNP3 UPC: 816341028050 Caliber: .22 ARC Barrel Length: 20" Material: 416-R Stainless Steel Rifling: 5R Finish: Nitride (inside and out) Barrel Description: Flame Fluted Barrel Type: Button Rifled Twist Rate: 1:7" Muzzle Thread Pattern: 1/2"x28 Extension Coating: Nickel Teflon Testing: Individually Magnetic Particle Inspected (MPI) Weight: 2.13 lbsDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
