It is manufactured in the USA and offers a combination of military specification dimensions, tolerances, and materials with added enhancements to elevate its performance beyond milspec standards, all at an economical price point.\u003c\/p\u003e\n\u003ch3 id=\"features\"\u003eFeatures\u003c\/h3\u003e\n\u003ch4 id=\"enhanced-performance\"\u003eEnhanced Performance\u003c\/h4\u003e\n\u003cp\u003eThe M-SPEC line features a full-auto style carrier with increased mass to enhance lock time and smooth operation. The entire carrier assembly is QPQ Nitride coated for increased corrosion resistance and durability. This specialized coating creates a very hard, smooth surface with a low coefficient of friction, contributing to the BCG's overall performance and reliability.\u003c\/p\u003e\n\u003ch4 id=\"high-quality-materials\"\u003eHigh-Quality Materials\u003c\/h4\u003e\n\u003cp\u003eThe carrier is precision machined from 8620 steel, case hardened, and hard turned\/ground to exact milspec dimensions. The bolt is manufactured from Carpenter 158 or 9310 steel, shot peened, and hard turned\/ground to meet military specifications. The Lantac CP-R360 domed head cam pin, precision-machined from 17-4PH stainless steel and hardened to H900 condition, further reduces friction and wear within the upper receiver.\u003c\/p\u003e\n\u003ch4 id=\"advanced-coating\"\u003eAdvanced Coating\u003c\/h4\u003e\n\u003cp\u003eThe QPQ Nitride coating is a specialized type of nitrocarburizing case hardening that creates a very hard, smooth surface.

This design results in a system that runs flatter with a smoother energy pulse, a softer start to carrier movement, and less pressurization of the upper receiver when running a suppressed barrel.\u003c\/p\u003e\n\u003ch3 id=\"specifications-1\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.7oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 8620 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Material\u003c\/strong\u003e: Carpenter 158 or 9310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: QPQ Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCam Pin\u003c\/strong\u003e: Lantac CP-R360, 17-4PH Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Key\u003c\/strong\u003e: Hard Chrome Lined, Grade 8 Fasteners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: Precision Machined to Mil-Spec Dimensions and Tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 id=\"additional-features\"\u003eAdditional Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShot Peening\u003c\/strong\u003e: Conducted with S110 shot, established by Almen Gage A-2 strip .006 -.008\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLifetime Warranty\u003c\/strong\u003e: Covers all defects in materials and workmanship\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 id=\"availability\"\u003eAvailability\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExport\u003c\/strong\u003e: Prohibited without a valid export license issued by the U.S. Department of State, Office of Defense Trade Controls, prescribed in the International Traffic in Arms Regulation (ITAR), Title 22, Code of Federal Regulations, Parts 120-130.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 id=\"additional-information\"\u003eAdditional Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMilitary\/LE Discount\u003c\/strong\u003e: Available, visit the FAQ page for details on how to obtain the discount code.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Insurance\u003c\/strong\u003e: Available for purchase if required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor more information or to purchase this product, please visit our website.\u003c\/p\u003e\n","brand":"LANTAC","offers":[{"title":"Default Title","offer_id":44685912801499,"sku":"01-MSPEC-556-NIT-BCG","price":170.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/1072\/7131\/files\/182991077.webp?v=1738344891","url":"https:\/\/www.atcostammo.com\/products\/lantac-5-56-223-m-spec-bolt-carrier-group-qpq-black-nitride","provider":"AtCostAmmo.com","version":"1.0","type":"link"}
