The Anderson Lower Parts Kit (LPK) has become a popular choice among AR-15 builders and enthusiasts due to its affordability and generally reliable components. This guide will delve into the specifics of Anderson LPKs, exploring their features, potential drawbacks, and considerations for those looking to incorporate one into their build.
What is an Anderson Lower Parts Kit?
An Anderson Lower Parts Kit is a collection of essential components needed to complete the lower receiver of an AR-15 style rifle. It typically includes the following:
- Lower Receiver Parts: These are the components that reside inside the lower receiver, making the firearm functional. This typically includes the trigger, hammer, disconnector, trigger pins, hammer pin, and safety selector.
- Other Components: Some kits may also include the grip, buffer tube, and buffer retainer pin. However, it's important to check the kit's contents, as this varies between manufacturers and retailers.
Crucially, the Anderson LPK does not include the lower receiver itself. You will need to purchase a stripped lower receiver separately. This is often where potential confusion arises, so clarifying this upfront is important.
Key Features and Considerations
Anderson LPKs are known for their competitive pricing, making them an attractive option for budget-conscious builders. However, it's essential to understand what you are getting for that price.
Pros:
- Affordability: This is the primary draw for many buyers. Anderson Manufacturing offers some of the most economical LPKs on the market.
- Generally Reliable: While not always considered top-tier in terms of quality, Anderson LPKs generally function reliably when properly installed.
- Widely Available: These kits are readily available from numerous online and brick-and-mortar retailers.
Cons:
- Material Quality: Compared to higher-end LPKs, the materials used in Anderson kits might be perceived as less durable or refined. This can translate to potentially shorter lifespan or increased wear over time.
- Finish Consistency: The finish on some Anderson components can be inconsistent, although this varies from batch to batch and is not universally experienced.
- Potential for Minor Issues: Some users have reported minor issues such as slightly rough surfaces or slightly inconsistent tolerances, requiring minor adjustments during installation. These issues, however, are not always prevalent.
Anderson LPK vs. Other Brands: A Comparison
Choosing an LPK involves weighing cost against quality. Higher-end brands like Aero Precision or BCM Gunfighter often boast superior materials and tighter tolerances, resulting in a smoother trigger pull and potentially more reliable function. However, these come at a significantly higher price point. Anderson Manufacturing provides a viable budget option for those seeking an affordable entry into AR-15 building.
Installation and Tips for Success
Installing an LPK requires careful attention to detail. Improper installation can lead to malfunctions or even safety hazards. Several excellent online resources offer step-by-step guides and videos that visually demonstrate the correct procedure. Always refer to these resources before attempting installation.
Key tips for success:
- Cleanliness: Ensure the lower receiver is clean and free from debris before installation.
- Proper Alignment: Precise alignment of components is critical.
- Lubrication: Lightly lubricating components can aid in smoother operation.
- Test Firing: After installation, always test fire your assembled AR-15 at a safe range with proper eye and ear protection.
Conclusion: Is an Anderson LPK Right for You?
An Anderson Lower Parts Kit can be a great choice for budget-minded AR-15 builders. However, it’s important to manage expectations. While they generally function reliably, they may not match the quality and longevity of higher-priced alternatives. Weighing the cost versus the desired quality is crucial in making the right decision. If you prioritize affordability and are comfortable with the potential for minor imperfections, an Anderson LPK is a viable option. If, however, reliability and premium components are top priorities, consider investing in a higher-end LPK from a reputable manufacturer. Thorough research and careful installation are key regardless of the chosen brand.
