When absolute reliability intersects with next-generation surface technology, the result is nothing short of revolutionary. Toolcraft, a trusted OEM manufacturer behind some of America's most elite M16 style bolt carrier groups, has elevated their legendary precision engineering with the latest advancement in coating technology - creating a BCG that sets new standards for durability, smoothness, and sustained performance. Diamond Like Coating, also known as Ionbonding, creates one of the hardest and most intrinsically lubricating surfaces, which is ideal for a high metal on metal wear prone part, like a BCG.
Key Features:
For over five decades, Toolcraft has been the silent force behind America's most elite AR-15 bolt carrier groups, manufacturing OEM components for premier military contractors and top-tier firearms manufacturers. Now, they've paired their legendary precision engineering with cutting-edge Diamond-Like Carbon coating technology to create the ultimate high-performance BCG.
DLC coating represents the pinnacle of modern surface enhancement, creating a nearly diamond-hard barrier that measures over 80 on the Rockwell C scale - harder than chrome and traditional nitride treatments. This ultra-slick surface achieves a coefficient of friction as low as 0.01, allowing the BCG to cycle with incredible smoothness while requiring minimal lubrication. Beyond reducing friction, DLC provides exceptional corrosion resistance and thermal stability, maintaining peak performance even in extreme conditions.
Precision-crafted from aircraft-grade 8620 steel and featuring a Carpenter 158 bolt, each component undergoes rigorous High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI). The properly staked 4130 steel gas key utilizes grade 8 fasteners, while the shot-peened bolt incorporates a tool steel extractor with enhanced spring and Crane O-ring for optimized reliability.
Technical Specifications:
Includes enhanced extraction spring with Crane O-ring for optimized reliability. Fully compatible with both semi-auto and select-fire platforms. When you demand uncompromising performance backed by decades of proven manufacturing excellence, accept nothing less than Toolcraft.
