Let’s Talk About Sons of Liberty Gun Works Full Auto Blaster Guts
The Sons of Liberty Gun Works Full Auto Blaster Guts is a lower parts kit designed for a specific purpose: completing or repairing full-auto AR-15 lower receivers. This kit, produced by Sons of Liberty Gun Works, boasts high-quality, mil-spec components meant to ensure reliability and longevity in demanding environments. It’s not your average AR-15 build kit, and understanding its intent and legal implications is crucial.
After years spent building and modifying AR platforms, I needed a reliable full-auto lower parts kit for a transferable machine gun repair. The availability of quality full-auto components has diminished, and I wanted a kit built to withstand the rigors of full-auto fire. This need led me to the Sons of Liberty Gun Works Full Auto Blaster Guts.
Upon opening the package, the immediate impression was one of quality. The individual components were neatly organized, and the finish on each part was flawless. The weight of the steel magazine catch and other parts felt reassuring compared to some of the lighter, commercially available LPKs I’ve encountered.
Compared to a standard mil-spec LPK from other brands or even a high-end aftermarket trigger pack, the Sons of Liberty Gun Works Full Auto Blaster Guts stands out due to its specifically intended use. While a standard LPK focuses on semi-automatic fire, this kit is designed to withstand the increased stresses of full-auto. I chose this kit over individual components from other manufacturers because I wanted a complete, matched set from a reputable source.
My first impression was a blend of excitement and caution. Excited because the parts looked exceptionally well-made, and cautious because understanding the legal aspects of owning and installing these parts is paramount. This isn’t a casual purchase; it’s a specialized component with significant regulatory considerations.
Real-World Testing: Putting Sons of Liberty Gun Works Full Auto Blaster Guts to the Test
First Use Experience
Testing this kit involved installing it in a registered, transferable machine gun lower receiver. The range session included firing thousands of rounds in both semi-automatic and full-automatic modes. The conditions were relatively clean and dry, typical for an indoor range environment.
The installation process was straightforward, identical to any standard AR-15 lower parts kit installation. No special tools or modifications were required. All the components fit perfectly and functioned as expected right out of the box.
The performance was flawless, with no malfunctions or failures to feed. The selector switch moved crisply between positions, and the trigger provided consistent and reliable fire control. I didn’t experience any issues whatsoever during the initial testing phase.
Extended Use & Reliability
After several months and thousands of rounds, the Sons of Liberty Gun Works Full Auto Blaster Guts has proven to be incredibly durable. There are no signs of excessive wear and tear on any of the components. The finish remains intact, and the trigger pull is still consistent.
Maintenance is simple, involving regular cleaning and lubrication as with any AR-15. I use a quality CLP (cleaner, lubricant, protectant) after each range session. The stainless-steel detents from KNS Precision Machine remain corrosion-free.
Compared to previous experiences with other lower parts kits in similar applications, this kit outperforms many due to the quality of the materials and construction. It gives me confidence that the rifle will function reliably even under heavy use.
