Finding the right left-handed upper parts kit can be tricky. This in-depth guide covers everything you need to know, from understanding what constitutes a left-handed kit to choosing the best one for your needs. We'll explore the differences, benefits, and considerations involved in selecting a left-handed upper receiver.
Understanding Left-Handed AR-15 Upper Receivers
The core difference between a standard and a left-handed AR-15 upper receiver lies in the ejection port. In a right-handed rifle, spent casings are ejected to the right side of the firearm. A left-handed upper reverses this, ejecting spent casings to the left. This seemingly minor change significantly impacts the shooting experience for left-handed shooters.
Why Choose a Left-Handed Upper Parts Kit?
-
Improved Comfort and Efficiency: Left-handed shooters will experience significantly improved comfort and shooting efficiency. The lack of hot brass hitting their face or body greatly enhances the shooting experience, reduces distractions and allows for more focused shooting.
-
Reduced Brass Deflection: Eliminates the risk of hot brass hitting the shooter’s face or body. This is a significant safety and comfort improvement.
-
Enhanced Accuracy: By removing the discomfort and distractions of ejected brass, shooters can focus more on target acquisition and shot placement, potentially leading to improved accuracy.
Key Features of a Left-Handed Upper Parts Kit
A complete left-handed upper parts kit typically includes:
- Left-handed Upper Receiver: The main component, featuring the reversed ejection port.
- Bolt Carrier Group (BCG): This is often ambidextrous, but some specialized kits might include a left-handed specific BCG.
- Charging Handle: While not always specifically “left-handed,” many shooters find left-side charging handles more ergonomic. This should be considered, but is not always included in every kit.
- Forward Assist: Often a standard component; ambidextrous forward assists exist but are not always included.
- Ejection Port Cover: A standard component, but essential for complete functionality.
- Dust Cover: Protects the internal components and is generally included.
Choosing the Right Left-Handed Upper Parts Kit
Selecting the ideal left-handed upper parts kit depends on several factors:
- Budget: Prices vary considerably depending on the manufacturer and included components.
- Brand Reputation: Research manufacturers with a solid reputation for quality and reliability. Look for reviews and user feedback.
- Materials: Consider the materials used in the construction. Forged aluminum upper receivers are generally preferred for their strength and durability.
- Compatibility: Ensure the kit is compatible with your existing lower receiver. Double-check specifications to avoid issues.
- Specific Needs: Consider any special features you might need or prefer, such as a specific type of charging handle or enhanced ergonomics.
Installation and Considerations
Installing a left-handed upper parts kit is generally straightforward if you have some experience working on AR-15s. However, if you're unfamiliar with the process, it's best to seek assistance from someone experienced or consult a detailed instructional guide specific to your kit. This avoids potential damage to your components and ensures correct assembly.
Potential Challenges
- Compatibility Issues: Carefully check compatibility with your lower receiver before purchasing and installing.
- Ambidextrous Components: Some parts (like the bolt carrier group and forward assist) may be compatible with both left and right-handed setups.
- Proper Lubrication: Always properly lubricate all components before installation and use.
Case Study: Comparing Two Popular Left-Handed Upper Parts Kits
While specific brands and models change frequently, the principle remains the same. Suppose we compare Brand A's kit, known for its affordability, and Brand B's, known for premium materials and features.
| Feature | Brand A | Brand B |
|---|---|---|
| Price | Lower | Higher |
| Material | Aluminum | Forged Aluminum, potentially other upgrades |
| Included Parts | Basic set: upper, BCG, basic charging handle | Enhanced set: potentially including upgraded charging handle, forward assist |
| Warranty | Limited | More comprehensive |
