The AR-15 platform's modularity is a key aspect of its enduring popularity. One area where builders often make choices is the upper receiver, specifically concerning the presence or absence of a forward assist. This article delves into the "no forward assist upper" receiver, exploring its pros, cons, and ideal applications.
Understanding the Forward Assist
Before we dive into the specifics of uppers without forward assists, let's quickly revisit the function of a forward assist itself. The forward assist is a small lever located on the right side of the upper receiver. Its purpose is to help chamber a round if the bolt carrier group fails to fully seat a cartridge during the charging handle manipulation. While useful in some situations, it's a component that many builders choose to omit for various reasons.
Why Choose a No Forward Assist Upper?
The decision to build or purchase an AR-15 with a no forward assist upper receiver is often driven by a combination of factors:
1. Weight Reduction:
Even a small component like the forward assist adds up. For those prioritizing a lightweight build, particularly for applications like competitive shooting or hunting where every ounce counts, removing it makes a noticeable difference.
2. Enhanced Reliability:
Paradoxically, omitting the forward assist can actually enhance reliability for some users. The argument is that if your ammunition and weapon are functioning correctly, a forward assist shouldn't be needed. Relying solely on proper charging handle manipulation fosters better shooting habits and reduces the potential for malfunctions stemming from incorrect forward assist usage.
3. Streamlined Aesthetics:
Many builders appreciate the cleaner, more minimalist aesthetic of a no forward assist upper receiver. The absence of the lever contributes to a sleeker look, aligning with the preferences of some shooters.
4. Cost Savings:
While the price difference may be minor, opting for a no forward assist upper can contribute to overall build cost savings.
Potential Drawbacks of a No Forward Assist Upper
While the advantages are compelling, it's crucial to acknowledge the potential drawbacks:
1. Increased Difficulty in Chambering Rounds:
Without the forward assist, you'll solely rely on the charging handle to chamber rounds. If you encounter issues (e.g., weak springs, ammunition inconsistencies), chambering a round could become more difficult.
2. Not Ideal for Harsh Environments:
In adverse conditions, such as those involving dirt, debris, or extreme temperatures, the absence of a forward assist might present challenges in reliably chambering ammunition.
3. Requires Proper Technique:
Success with a no forward assist upper depends heavily on proper charging handle manipulation. Improper technique could lead to malfunctions that a forward assist might otherwise mitigate.
Who Should Choose a No Forward Assist Upper?
A no forward assist upper receiver is a great choice for:
- Experienced AR-15 builders and shooters: Individuals comfortable with proper weapon handling and ammunition selection are best positioned to take advantage of the benefits without encountering significant issues.
- Competitors: The weight reduction makes this a popular choice in the competitive shooting community.
- Those prioritizing a lightweight build: Any situation requiring a minimized weight is a strong candidate for a no forward assist build.
Conclusion: A Matter of Choice and Proficiency
The decision of whether to use a no forward assist upper receiver boils down to individual needs and proficiency. While it offers potential benefits in terms of weight, reliability (in some contexts), aesthetics, and cost, it also requires a higher degree of user skill and proper maintenance. Thorough understanding of the weapon's mechanics and careful selection of ammunition are essential considerations. Weigh the pros and cons carefully before making your choice.
