FAXON MATCH BBL 300BLK 7.5" GNR

Faxon Match Series Gunner Profile 7.5 1:5T Pistol Gas 300 BLK AR-15 Barrel (15B35P7NGQ-5R-NP3) - The Faxon Match Series 7.5 300 BLK Gunner Profile barrel is built for the most common real-world 300 Blackout use case: a compact AR pistol / PDW setup running heavy subsonic ammo often suppressed where bullet stability and consistent cycling matter more than anything else. A fast 1:5 twist (RH) helps stabilize longer heavier 300 BLK projectiles in short barrels and Faxon•s Match Series architecture is designed to keep performance repeatable: 416R stainless steel with 5R button rifling to help reduce jacket deformation and fouling versus traditional sharp-shouldered rifling. If you're building a short 300 BLK that needs to run subs (and still behave when you switch to supers) this SKU is engineered to remove uncertainty. - Every Faxon rifle barrel begins life inside our Greater Cincinnati manufacturing operation where we control critical steps from raw steel to finished barrel. Blanks are cut drilled reamed and rifled in-house then stabilized via stress relief before final profiling. All Faxon barrels are 100% magnetic particle inspected (MPI) and Faxon Match Series barrels are finished with a durable Salt Bath Nitride / QPQ for corrosion resistance and wear protection. For this specific barrel critical features are verified using air-gauge bore checks custom hardened gauges coordinate measuring machine (CMM) verification of chamber geometry along with 300 BLK GO/NO-GO headspace verification. - Suppressor ecosystem tip: If you plan to shoot both subsonic and supersonic loads-especially suppressed-pair this barrel with a tunable gas solution. An adjustable gas block and appropriate buffer/spring tuning can reduce blowback smooth recoil impulse and improve reliability across ammo types. - Key Features & Tech Specs - Platform: AR-15 - Series: Match Series - Caliber: 300 AAC Blackout (300 BLK) - Barrel Length: 7.5 - Profile: Gunner - Gas System: Pistol-length - Twist Rate: 1:5 (Right-Hand) - Rifling: 5R button rifled - Steel: 416R stainless - Finish: Salt Bath Nitride / QPQ - Muzzle Threads: 5/8x24 - Gas Block Journal Diameter: .750 (print-controlled at .7490-.7497) - Gas Block Journal Length: 1.900 - Gas Port Diameter: .104 - Gas System Location (port reference): 4.846 (pistol gas reference) - Marking: Roll mark behind gas block journal: .300 BLK 1-5T - Inspection: 100% MPI air-gauged bore check custom hardened gauging CMM-verified chamber geometry 300 BLK GO/NO-GO headspace verification - Made In: USA (Greater Cincinnati Ohio)
