SKU: CTSP64028
The Colt 5.56 Bolt Carrier Group is a mil-spec Parkerized component engineered to military standards for 5.56 NATO and .223 Remington platforms. Built to the original specifications that define AR-platform reliability, this bolt carrier group delivers the performance operators and competitive shooters demand from a core weapon system component.
Parkerized finish provides robust corrosion resistance in harsh field environments—salt air, moisture, and thermal cycling—while maintaining the lower friction characteristics essential for reliable cycling across temperature extremes. The mil-spec design ensures full compatibility with standard AR-15 receivers and upper assemblies, with no fitting or modification required. Weighing 0.75 lbs, this is a direct-fit drop-in upgrade or replacement component for rifle platforms chambered in 5.56 NATO or .223 Remington.
This component is built for patrol officers maintaining duty rifles, military personnel requiring spec-compliant replacement parts, precision shooters building or rebuilding precision platforms, and gunsmiths stocking inventory. Whether serving as a maintenance replacement or a core component in a new build, mil-spec bolt carrier groups from Colt's Manufacturing set the baseline for reliability that other manufacturers are measured against.
The 5.56 bolt carrier group remains one of the most critical wear items in the AR platform ecosystem. Colt's Manufacturing continues to deliver mil-spec variants that meet the original M16/M4 standards, ensuring shooters and operators have access to proven, unmodified performance without premium pricing.
