Noveske Mil-Spec Buffer Tube Features The Noveske Mil-Spec Buffer Tube is machined to mil-spec dimensions for 7.62x51mm and 6.5 Creedmoor large frame AR-10 style rifles giving builders a receiver extension that matches factory Noveske N6 rifles exactly. Its 6 position design allows length of pull adjustment to fit the shooter and the stock in use which matters for comfort behind heavier recoiling large frame cartridges. The hard coat anodized finish resists corrosion and wear from repeated handling and field use. This buffer tube is built to the same standard Noveske uses on its own large frame rifles. Pairing this extension with N6 springs and H3 buffers replicates the exact setup Noveske engineers into its N6 line giving builders confidence that the system will cycle reliably. The A5 length receiver extension is a known quantity among large frame AR builders looking for consistent recoil management and reliable cycling. Its black finish matches most AR-10 builds without drawing attention. For anyone assembling or upgrading a 7.62 or 6.5 Creedmoor large frame rifle this buffer tube offers a proven factory-grade foundation.
