{"product_id":"lantac-e-bcg-556-side-charge-nib","title":"LanTac - Enhanced BCG DI Side Charger for .223\/5.56","description":"\u003cp\u003eThe \u003cb\u003eLANTAC E-BCG Gen2 DI Side Charger\u003c\/b\u003e is an enhanced bolt carrier group designed specifically for .223\/5.56 caliber firearms. This BCG is not compatible with standard AR-15 upper receivers and must be used with a side charging upper receiver. For optimal fit, LANTAC recommends pairing it with their LA-N15 Raven Side Charging Billet Upper Receiver. Engineered in an M16 full auto style, it provides increased mass and lock time.\u003c\/p\u003e\u003cp\u003eConstructed from \u003cb\u003e8620 Steel\u003c\/b\u003e, the bolt is made from Carpenter 158 or 9310 steel and is Magnetically Particle Inspected for reliability. The entire carrier assembly is treated with a \u003cb\u003eQPQ Nitrided finish\u003c\/b\u003e for enhanced corrosion and wear resistance. The patented design features unique shrouded and forward-facing gas ports, resized for improved gas venting, resulting in a flatter, smoother operation with reduced upper receiver pressurization, especially when using a suppressed barrel.\u003c\/p\u003e\u003cp\u003eThe BCG's flared boss at the tail enhances lock position consistency, improving accuracy. The LANTAC CP-R360 domed head cam pin, crafted from 17-4PH Stainless Steel, reduces wear within the upper receiver. Weighing 11.7oz (excluding handle), this BCG promotes smoother operation and increased lock time. Gas keys are properly staked at four points, using grade 8 fasteners. The forward porting and unique shape assist in reducing pressurization inside the upper receiver, though it's not a complete solution for over-gassed rifles.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCompatibility:\u003c\/b\u003e Requires side charging upper receiver\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e 8620 Steel carrier, Carpenter 158 or 9310 bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFinish:\u003c\/b\u003e QPQ Nitrided for corrosion and wear resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDesign:\u003c\/b\u003e M16 full auto style for increased mass and lock time\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGas Ports:\u003c\/b\u003e Shrouded and forward-facing for improved venting\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight:\u003c\/b\u003e 11.7oz (excluding handle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCam Pin:\u003c\/b\u003e LANTAC CP-R360 domed head, 17-4PH Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFasteners:\u003c\/b\u003e Grade 8, properly staked gas keys\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMade in:\u003c\/b\u003e USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWarranty:\u003c\/b\u003e Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eColor:\u003c\/b\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eType:\u003c\/b\u003e Bolt Carrier Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSubCategory:\u003c\/b\u003e Bolts \u0026amp; Bolt Carrier Groups\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProduct UPC:\u003c\/b\u003e 614347732274\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eModel:\u003c\/b\u003e Enhanced Side Charger Bolt Car\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eManufacturers Part Number:\u003c\/b\u003e 01-UP-SC-NIB-EBCG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LanTac USA LLC","offers":[{"title":"Default Title","offer_id":47379729023065,"sku":"RSR-LAN01-UP-SC-NIT-EBCG","price":310.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9860\/2329\/files\/lantac_RSR-LAN01-UP-SC-NIT-EBCG-1.jpg?v=1791189205","url":"https:\/\/mountainready.online\/products\/lantac-e-bcg-556-side-charge-nib","provider":"mountainready.online","version":"1.0","type":"link"}
