Wilson Combat AR-15 Low Mass Bolt Carrier Assembly

Overview

The Wilson Combat AR-15 Low Mass Bolt Carrier Assembly is precision-machined for enhanced reliability and performance in 5.56 NATO and compatible case head platforms, including .223 Remington, .300 Blackout, .204 Ruger, .300 HAM'R, and 7.62x40 WT. The lightweight carrier is machined from 8620 hardened steel with forward assist cuts and a polished nickel boron coating that provides corrosion resistance, increased lubricity, and easy cleanup. The assembly features a bolt precision-machined from aerospace-grade 9310 tool steel, subjected to Magnetic Particle Inspection (MPI) for optimal structural integrity, along with a machined ejector and extractor. The gas key is properly staked using Grade 8 fasteners to prevent gas leakage under pressure. This low-mass design promotes quicker lock-up times, improved recoil control, and faster follow-up shots when paired with an adjustable gas block.
