Toolcraft 7.62×39 Bolt Carrier Group – DLC

The Toolcraft 7.62×39 Bolt Carrier Group – DLC is a full-auto profile M16 BCG designed for AR-15 platforms chambered in 7.62x39mm. Manufactured in the U.S.A. using high-grade materials and covered by a lifetime warranty, this bolt carrier group delivers enhanced performance and long-term reliability. Its advanced Diamond-Like Carbon (DLC) finish makes it a preferred choice for demanding shooting environments.

This BCG features a 9310 steel bolt and an 8620 steel carrier, both treated with a DLC coating. Known for its ultra-low coefficient of friction, the DLC finish is self-lubricating in dry conditions, highly resistant to wear, and among the hardest coatings available, rated at 90 Rockwell. Carbon fouling easily wipes away with minimal effort, making cleaning and maintenance simple even after extended use.

The bolt assembly is MPI-inspected and includes a 4140 steel extractor and a bolt face depth of .125″. A Mil-Spec O-ring and triple gas rings ensure consistent sealing and reliable case extraction. Supporting components include a 416 stainless steel firing pin, a 4130 steel gas key secured with Grade 8 fasteners, and a 8620 steel cam pin. Every detail of this BCG is built to meet military specifications and support high-pressure operation.

This M16 full-auto profile is ideal for builders looking for increased mass and smoother cycling. Whether you’re assembling an AR-47 or upgrading an existing 7.62x39mm upper, this DLC-coated bolt carrier group offers the right balance of rugged durability and high-performance engineering for reliable field use.

All Toolcraft Bolt Carrier Groups sold by Arm or Ally are factory-coated and sourced directly from the manufacturer, preserving Toolcraft’s full warranty. Units coated by third-party vendors may void this protection. For a high-end, easy-to-clean, wear-resistant upgrade to your 7.62×39 AR build, this DLC BCG delivers top-tier performance backed by a proven name.
