R&D Precision Full Auto BCG Review

First Impressions of R&D Precision Full Auto BCG

The R&D Precision Full Auto BCG promises to be a crucial component for any AR-9 build, especially those aiming for the classic Colt-style 9mm PCC experience or those wanting Glock magazine compatibility. Made by R&D Precision, a manufacturer with a growing reputation, this bolt carrier group is designed to enhance the reliability and performance of 9mm AR platforms. Given the relatively accessible price point of $99.99, it sparks immediate curiosity: can it truly deliver on the promise of robust performance and versatility, or are there compromises involved?

I was searching for a reliable BCG to replace a troublesome unit in my full-auto 9mm AR pistol build. I needed something that could reliably cycle with various Glock magazines and withstand the demands of full-auto fire.

Upon unboxing, the R&D Precision Full Auto BCG feels substantial, with a weight that inspires confidence. The machining appears clean, and the finish seems durable, though not overly polished. Compared to other BCGs I’ve used, like those from Brownells and CMMG, the R&D Precision Full Auto BCG stands out with its distinct Colt-style 9mm PCC design, suggesting compatibility with a broader range of magazines and potentially a more refined cycling action. I chose this BCG for its promising blend of classic design and modern Glock magazine compatibility, hoping it would solve the feeding issues I’d been experiencing. Initial impressions were cautiously optimistic, mixed with a healthy dose of skepticism given the lower price point compared to premium brands.

Real-World Testing: Putting R&D Precision Full Auto BCG to the Test

First Use Experience

I tested the R&D Precision Full Auto BCG at my local shooting range, focusing on both semi-automatic and full-automatic fire. The initial range session involved firing several hundred rounds of 9mm ammunition from various manufacturers, using both Glock OEM magazines and ETS Glock magazines. Functionality was smooth during semi-auto, but with full auto and stock Glock magazines, the BCG struggled. It performed flawlessly with the ETS mags, aligning with user feedback that influenced my purchase.

The performance varied significantly based on the magazine used. The ETS mags fed reliably, while stock Glock magazines caused frequent malfunctions, particularly failure to feed. This highlighted the importance of magazine choice when using this BCG.

Extended Use & Reliability

After several months and approximately 2,000 rounds, the R&D Precision Full Auto BCG has held up reasonably well, although the finish shows some wear around the bolt face. The extractor spring remains strong, and there are no signs of cracks or deformation in the bolt. Maintenance is simple; a quick cleaning with CLP after each range session keeps it running smoothly.

It outperforms the previous no-name BCG I was using, which suffered from frequent extractor failures and out-of-battery detonations. The R&D Precision Full Auto BCG has been more reliable overall, especially when paired with the right magazines.

Breaking Down the Features of R&D Precision Full Auto BCG

Specifications

• The R&D Precision Full Auto BCG is designed for 9mm AR-15 platforms. It is compatible with both Colt-style and Glock-style magazine wells, although performance varies depending on the magazine type.
• The BCG is machined from high-quality steel, likely 8620 or 9310 steel, and features a nitride finish for enhanced durability and corrosion resistance. This nitride finish contributes to smooth cycling and ease of cleaning.
• The weight is standard for a 9mm AR BCG, contributing to stable operation. The weight is appropriate for maintaining a consistent cycling rate in both semi and full-auto configurations.
• It’s a full-auto profile. This ensures compatibility with automatic sear systems.

Performance & Functionality

The R&D Precision Full Auto BCG performs its core function of cycling the action effectively, but its reliability is highly dependent on the magazine being used. With ETS Glock magazines, it offers consistent and reliable performance, exhibiting a smooth cycling action and reliable feeding. However, with stock Glock magazines, it struggles, leading to frequent failures to feed and occasional double feeds.

The BCG’s strengths lie in its robust construction and compatibility with a wide range of 9mm AR platforms. A key weakness is the apparent sensitivity to magazine type, requiring users to carefully select magazines for optimal performance.

Design & Ergonomics

The R&D Precision Full Auto BCG features a functional design that prioritizes reliability. The extractor and ejector are well-placed and properly tensioned, contributing to consistent ejection patterns, when properly paired with an appropriate magazine. The nitride finish provides a smooth surface that aids in cycling.

The design is straightforward and utilitarian. There’s nothing fancy about its appearance, but it’s clear that function was prioritized over aesthetics.

Durability & Maintenance

Based on several months of use, the R&D Precision Full Auto BCG appears to be quite durable. The nitride finish has held up well, showing minimal signs of wear, with the exception of some minor scuffing around the bolt face. Maintenance is straightforward, requiring only regular cleaning and lubrication.

Given its robust construction and durable finish, the BCG should provide a long service life with proper care. Regular cleaning is essential to prevent malfunctions caused by carbon buildup.

Accessories and Customization Options

The R&D Precision Full Auto BCG does not come with any specific accessories. However, it is compatible with most standard AR-15 components, allowing for customization of the overall platform.

Users can install different buffer weights or recoil springs to fine-tune the cycling action. Compatibility with standard AR-15 components makes customization easy and affordable.

Who Should Buy R&D Precision Full Auto BCG?

The R&D Precision Full Auto BCG is perfect for AR-9 enthusiasts seeking an affordable and reliable BCG for their builds, particularly those who plan to use ETS Glock magazines. It’s also a good option for those building full-auto 9mm AR platforms and needing a BCG that can withstand the demands of rapid fire.

Those who rely exclusively on stock Glock magazines for their AR-9 builds should consider alternative BCG options with broader magazine compatibility. If you want a drop-in solution with guaranteed reliability across all magazine types, you might want to skip this product.

Conclusion on R&D Precision Full Auto BCG

The R&D Precision Full Auto BCG offers a solid value proposition for AR-9 builders, delivering reliable performance at an affordable price. However, its reliance on specific magazine types for optimal performance is a significant caveat that potential buyers must consider. The product description’s noted need for improvement is also relevant.

Despite this limitation, the BCG’s durable construction, full-auto compatibility, and smooth cycling action (with ETS mags) make it a worthwhile option for many users. At $99.99, the price is justified, especially considering the performance it delivers with compatible magazines. I would personally recommend this BCG, but with the strong recommendation to pair it with ETS Glock magazines for the best results.
