Who This BCG Is For
Builders and Upgraders: Those assembling new AR builds or replacing worn carriers with a quality aftermarket BCG.
Frequent Shooters: Users who value a carrier designed to withstand high-round counts and frequent cycling.
Range, Duty & Training: Ideal for shooters who require dependable extraction, reliable timing, and reduced maintenance downtime.
Collectors & Restorers: Owners looking to maintain factory-like fit and form while upgrading surface protection with a phosphate + chrome finish.
Performance & Use Notes
The phosphate exterior combined with chrome lining on high-wear surfaces reduces the impact of corrosion and eases cleaning by resisting carbon adhesion. This combination supports reliable extraction and consistent cycling over long shooting sessions.
Phase 5’s BCG-M16 is intended to be used with appropriate bolt gas rings, properly staked gas keys, and correct headspacing components; always verify compatibility with your specific upper receiver and barrel configuration. (If your build uses non-standard gas systems or suppressed/barrel-length specific tuning, consult a qualified armorer or the Phase 5 fitment guidance.)
Maintenance & Care
Routine inspection, cleaning, and lubrication will maximize the life of the BCG. Remove carbon build-up from the bolt face, lugs, and carrier key at regular intervals and inspect gas key staking and fasteners for security.
Use recommended lubricants for AR-platform components and follow your rifle manufacturer’s maintenance schedule to preserve function and safety.
Replace worn parts (gas rings, extractor springs, ejector, etc.) as needed to maintain optimal extraction and ejection.
