Colt M4 Original Equipment Rifle 5.56 Nato 16.1 inch 30 rounds Matte Black

The Colt M4 OEM Rifle 5.56 NATO 16.1 in. Matte Black 30 rd. from Colt's OEM Series brings the time-tested M4 platform into a builder's-ready package that's ideal for shooters who want a no-compromise foundation for customization, duty use, range training, or personal protection and sport shooting. The semi-automatic carbine features a chrome-lined 16.10" barrel with a 1:7" twist and muzzle brake for reliable accuracy and reduced recoil with modern 5.56x45mm loads, an A2 front sight and black hardcoat anodized/phosphate finish for durable corrosion resistance, and an aluminum receiver that keeps weight manageable while maintaining strength. This OEM1 variant ships without handguard, buttstock, trigger guard and rear sight so it accepts most aftermarket drop-in style handguards using the factory barrel nut and retaining ring, and is also available with a low-profile gas block for users building low-profile rails or suppressor-ready setups. With a standard trigger, right-hand ergonomics, 32" overall length and familiar safety lever, it's suited to tactical drills, competition and defensive roles; note this firearm requires transfer through an FFL. The Colt name and M4 lineage mean proven parts compatibility, veteran service-proven reliability and straightforward upgrade paths for operators and custom builders.
