Product DescriptionThe KAK Industry K-SPEC Low Mass Bolt Carrier Group (BCG) is engineered for AR-15 builds with properly tuned gas and buffer systems where reduced reciprocating mass and smooth cycling are desired. This assembly features an aluminum carrier with a satin gold anodized finish (matched to Mil-Spec buffer anodize color), a 9310 dual-ejector bolt, and an NP3 cam pin to enhance lubricity and help promote reliable operation. It includes a down-vent design and is recommended for mid-length, rifle-length, or similar gas systems. This BCG is not intended for hard-use applications and is considered a consumable wear component.Product Highlights Low mass K-SPEC AR-15/M16 bolt carrier group designed to support faster cycling and reduced recoil impulse in tuned setups Aluminum carrier with satin gold anodized finish (Mil-Spec buffer anodize color match) 9310 dual-ejector bolt for strong extraction and enhanced reliability NP3 cam pin for smoother cycling and improved corrosion resistance Down-vent design with recommended use on mid-length, rifle-length, or similar gas systemsSpecs Brand: KAK Industry Product Type: Bolt Carrier Group (BCG) Platform: AR-15 / M16 Caliber: 5.56 Series/Model: K-SPEC Carrier Material: Aluminum Carrier Finish/Color: Satin Gold Anodized Bolt Material: 9310 (Dual Ejector) Cam Pin: NP3 Gas System Recommendation: Mid-length, Rifle-length, or similar Design Feature: Down Vent UPC: 811163036061 Manufacturer Part Number: 425-0510-002Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
