Bravo Company BCM M16 Bolt Carrier Group BCG (MPI)

Engineered for Performance, Trusted for Reliability

The Bravo Company Manufacturing (BCM) M16 Bolt Carrier Group (BCG) is engineered to meet and exceed MIL-SPEC standards for AR-15, M16, and M4 platforms. This complete BCG, with a parkerized exterior and chrome-lined interior, delivers unparalleled durability, reliability, and compatibility.  Some publications and professional reviewers have commented that BCM makes the best available BCG, and independent testing has shown the Bravo bolt carrier group to have a very long life expectancy.

Precision and reliability are paramount when choosing a bolt carrier group for your rifle. The BCM BCG ensures that you have the best materials and engineering at your disposal. Made from Mil-Spec Carpenter No. 158 steel, this BCG offers enhanced strength and durability. Each component is meticulously crafted and rigorously tested, guaranteeing your rifle functions flawlessly under all conditions.

Choosing a substandard bolt carrier group can lead to unreliable cycling, increased wear, and, ultimately, weapon malfunction. In high-stress situations, where performance and reliability are critical, a malfunctioning BCG can compromise the entire mission or shooting experience. Standard BCGs may not endure the rigors of extensive use, leading to failures and poor performance.

The BCM M16 Bolt Carrier Group addresses these problems with military-grade precision and reliability. Each BCG undergoes High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to ensure the highest quality and safety standards. Built to last with rigorous military specifications, this BCG offers dependable performance with enhanced durability and precise engineering.

Key Features

  • Material: MIL-SPEC Carpenter No. 158 steel for superior strength.
  • Finish: Parkerized exterior with chrome-lined carrier for corrosion resistance.
  • Gas Key: Chrome-lined, heat-treated, and properly staked using Grade 8 fasteners.
  • Testing: High Pressure Tested (HPT) and Magnetic Particle Inspected (MPI) for quality assurance.
  • Extractor: Tool steel extractor with BCM extractor spring for consistent extraction.
  • Durability: Shot peened bolt for increased strength and longevity.

The Bravo Company Manufacturing (BCM) M16 Bolt Carrier Group is crafted with meticulous precision and adheres to stringent military specifications. The bolt assembly is made from MIL-SPEC Carpenter No. 158 steel, a material renowned for its exceptional strength and durability. To enhance its toughness further, the bolt is shot peened, improving resistance to stress and fatigue.  In high performing military grade bolts, Charlie's normally sees either C-158 or 9310 steel alloys.  The two metals are very similar, and different test labs have different opinions on which is best.  For us, it might be an academic argument, as both are incredibly resilient.  

The interior of the carrier is chrome-lined, ensuring smooth operation and resistance to wear and corrosion. The gas key, a critical component for proper gas system function, is chrome-lined, heat-treated, and firmly secured to the carrier using Grade 8 hardened fasteners, and staked, per military standards.. This guarantees a secure attachment and reliable functioning even under high-stress conditions.  These specifications are table stakes for a durable M16 full auto BCG, and Bravo Company checks the necessary boxes.

To provide additional assurance, the bolt is subjected to High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to meet the highest standards of safety and quality. These tests ensure that potential flaws are identified and corrected before the BCG reaches the shooter.

The tool steel extractor and ejector are machined to precision, and the inclusion of the BCM extractor spring, black extractor insert, and MIL-SPEC crane O-ring contribute to reliable and consistent performance. The entire assembly is designed to function seamlessly in AR-15, M16, and M4 platforms, providing users with confidence in their weapon's reliability.

An often-overlooked feature of the BCM M16 Bolt Carrier Group is the use of a tool steel extractor combined with the BCM extractor spring. This combination, including a black extractor insert and MIL-SPEC crane O-ring, ensures reliable and consistent extraction, even under the most demanding conditions. This attention to detail highlights BCM’s commitment to providing a dependable and high-performing bolt carrier group.
