Complete Uppers: BCG and CH—A Deep Dive into AR-15 Component Selection
Choosing the right upper receiver for your AR-15 is crucial for performance, reliability, and overall shooting experience. This guide delves into two popular manufacturers known for their quality: Bravo Company Manufacturing (BCM) and Centurion Arms (CH). We'll compare their offerings, highlighting key features and considerations to help you make an informed decision.
Understanding Upper Receiver Components
Before diving into specific brands, let's briefly review the key components of an AR-15 upper receiver group:
- Upper Receiver: The main housing, accepting the bolt carrier group and barrel. Material (usually 7075-T6 aluminum) and manufacturing processes significantly impact durability and accuracy.
- Barrel: The heart of the firearm, responsible for propelling the projectile. Factors such as length, profile, and material (e.g., chrome-lined, stainless steel) heavily influence performance.
- Bolt Carrier Group (BCG): This reciprocating assembly moves the bolt, locking and unlocking the breech. Material quality and manufacturing tolerances are paramount for reliable function.
- Handguard: Protects the barrel and gas tube, and can incorporate mounting points for accessories. Material (aluminum, polymer) and design greatly affect heat dissipation and modularity.
- Gas System: Regulates gas pressure from the barrel to cycle the action. Length (carbine, mid-length, rifle) affects performance and recoil characteristics.
- Charging Handle: Manually cycles the bolt, typically located on the right side of the upper receiver. Ergonomics and ease of manipulation are important considerations.
Bravo Company Manufacturing (BCM) Uppers: A Reputation for Reliability
BCM enjoys a strong reputation among AR-15 enthusiasts for producing high-quality, reliable components. Their uppers often feature:
- High-quality materials: BCM uses premium materials and stringent quality control, resulting in durable and precise uppers.
- Durable finishes: Their finishes are designed to withstand the rigors of use and provide excellent corrosion resistance.
- Precise manufacturing: BCM's meticulous manufacturing processes ensure consistent performance and accuracy.
- Wide range of options: They offer a variety of barrel lengths, profiles, and handguard options to suit different preferences and applications.
Key BCM Upper Features: Look for features like their forged upper receivers, M-LOK compatible handguards, and their renowned BCM Gunfighter charging handle.
Centurion Arms (CH) Uppers: Innovation and Performance
Centurion Arms is another respected manufacturer known for innovative designs and high-performance components. Their uppers frequently incorporate:
- Unique features: CH often incorporates patented features and designs that enhance performance and ergonomics. Their C4 upper receiver is a prime example of this.
- Advanced materials: CH sometimes uses advanced materials for enhanced durability and performance.
- High-quality machining: Precise machining ensures compatibility and accuracy.
- Focus on modularity: CH uppers frequently boast exceptional modularity, allowing for easy customization.
Key CH Upper Features: Look for their unique receiver designs, often with integrated features and proprietary components.
BCG Considerations: Matching the Upper and Lower
The Bolt Carrier Group (BCG) is a crucial component that must function seamlessly with the upper receiver. While BCM and CH both produce high-quality BCGs, ensure compatibility before purchasing. Generally, using the same manufacturer's BCG and upper receiver is recommended for optimal performance and reliability. Always check manufacturer specifications for compatibility.
Choosing the Right Upper for You: BCM vs. CH
The best upper receiver for you depends on your individual needs and preferences. Consider these factors:
- Budget: Both BCM and CH products are generally higher-end and reflect that in their pricing.
- Intended use: Are you building a precision rifle, a home defense weapon, or something else?
- Desired features: Do you need specific features like a particular handguard, barrel length, or gas system?
- Compatibility: Ensure compatibility with your existing lower receiver and other components.
Ultimately, both BCM and CH manufacture excellent AR-15 uppers. The choice comes down to individual preferences, budget, and specific needs. Thorough research and careful consideration will help you select the perfect upper to complete your build.
