Constructed from 4150 Chrome Moly Vanadium (CrMoV) steel and finished with a durable Black Nitride coating, this barrel delivers outstanding corrosion resistance, heat tolerance, and long service life. At 10.5 inches in length, it is ideally suited for compact and SBR-style AR-15 configurations. The barrel features a 1:7 twist rate for optimal stabilization of a wide range of 5.56 NATO projectiles, a Government profile for the right balance of weight and rigidity, and a carbine-length gas system for reliable cycling. The muzzle is threaded 1\/2x28, compatible with most standard AR-15 muzzle devices. Button rifling ensures a consistent, smooth bore for improved accuracy and easier cleaning.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium 4150 CrMoV Steel Construction\u003c\/strong\u003e - Manufactured from 4150 Chrome Moly Vanadium steel for superior strength, durability, and extended barrel life under high round counts.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlack Nitride Finish\u003c\/strong\u003e - The inside and outside Black Nitride finish provides excellent corrosion resistance and hardness, reducing friction and wear for consistent performance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Rifled Bore\u003c\/strong\u003e - Button rifling produces a precise, uniform bore with excellent concentricity, contributing to tighter groups and enhanced accuracy.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbine-Length Gas System, 1:7 Twist Rate\u003c\/strong\u003e - The carbine-length gas system ensures reliable cycling in a compact platform, while the 1:7 twist stabilizes a broad spectrum of 5.56 NATO loads including heavier projectiles.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1\/2x28 Threaded Muzzle \u0026amp; Government Profile\u003c\/strong\u003e - Ready for standard AR-15 muzzle devices right out of the box, with a Government profile that balances weight savings with stiffness for a well-rounded build.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e CMC Triggers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e BBL556002\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 850040016932\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56x45 NATO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 10.5\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System:\u003c\/strong\u003e Carbine Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Government\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Threading:\u003c\/strong\u003e 1\/2x28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4150 Chrome Moly Vanadium (CrMoV) Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling:\u003c\/strong\u003e Button Rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Platform:\u003c\/strong\u003e AR-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 1.8 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
