First Impressions of Sons of Liberty Gun Works Blaster Guts
The Sons of Liberty Gun Works (SOLGW) Blaster Guts is a lower parts kit designed to provide AR-15 platform rifles with high-quality, mil-spec components. SOLGW built a reputation for reliability and durability, and this LPK aims to deliver that reputation directly into your build. It promises enhanced trigger performance, robust construction, and guaranteed longevity, making it an intriguing option for both seasoned builders and first-time AR enthusiasts.
I decided to purchase the Blaster Guts kit as I was embarking on a new AR build, aiming for a rifle that would be both reliable for defensive purposes and enjoyable for range days. I wanted to avoid the pitfalls of some budget LPKs, which often suffer from inconsistent trigger pulls and questionable durability. The SOLGW name and the promise of enhanced trigger performance caught my eye, especially considering the reasonable price point.
Upon unboxing, the first thing I noticed was the heft and finish of the components. The SOLGW parts have a quality feel. Unlike some cheaper kits that feel lightweight and almost toy-like, the Blaster Guts parts felt solid and well-made. The nickel PTFE coating on the trigger and hammer gave a smooth, almost polished appearance, hinting at the promised improved trigger pull.
I was also considering a standard mil-spec LPK from a reputable manufacturer like Daniel Defense and a more expensive aftermarket trigger assembly from Geissele. I ultimately chose the SOLGW Blaster Guts because it seemed to strike a balance between quality and cost. I preferred the idea of a drop-in kit with enhanced trigger performance over a completely standard mil-spec setup, but I wasn’t ready to commit to the higher price tag of a premium aftermarket trigger.
My initial impression was positive. The quality of the components and the promise of an improved trigger instilled confidence. I was excited to install the Blaster Guts kit and see how it would perform.
Real-World Testing: Putting Sons of Liberty Gun Works Blaster Guts to the Test
First Use Experience
I first tested the Sons of Liberty Gun Works Blaster Guts kit at my local outdoor shooting range. The weather was partly cloudy with a slight breeze, providing decent conditions to zero my newly built rifle and evaluate the LPK. I put approximately 200 rounds of mixed ammunition through the rifle, including both brass and steel cased ammo.
The initial trigger pull felt significantly smoother and cleaner than a standard mil-spec trigger. The take-up was minimal, with a crisp break and a predictable reset. There were no noticeable grittiness or stacking.
One minor issue arose: the safety selector was initially quite stiff. It required a bit more force than I would have liked to switch between safe and fire. This loosened up after some use and lubrication.
Extended Use & Reliability
After several months and over 1000 rounds, the Sons of Liberty Gun Works Blaster Guts kit has proven to be reliable. There have been no malfunctions or failures related to the LPK components. The trigger pull has remained consistent.
I have noticed minimal wear and tear on the components. The nickel PTFE coating on the hammer and trigger still looks relatively new, with no signs of chipping or flaking. The only noticeable wear is on the safety selector where it interfaces with the detent, which is typical.
Maintaining the Blaster Guts kit is straightforward. Regular cleaning and lubrication, just like any other AR-15, are sufficient. I use a quality gun oil on the trigger, hammer, and other moving parts after each range session.
Previously, I’ve used a standard mil-spec LPK from Palmetto State Armory, and the SOLGW Blaster Guts noticeably outperforms it. The trigger is significantly smoother and more consistent. I would also rate the durability as superior based on my observations after the first 1000 rounds.
Breaking Down the Features of Sons of Liberty Gun Works Blaster Guts
Specifications
The Sons of Liberty Gun Works Blaster Guts includes all the necessary components for a complete AR-15 lower receiver assembly. This includes the trigger, hammer, disconnector, safety selector, bolt catch, magazine catch, takedown pins, and all associated springs and detents.
The bolt catch and safety selector are investment cast from AISI8620 steel. They meet the USGI TDP (Technical Data Package) specifications, ensuring proper dimensions and material properties for reliable function. The magazine catch and takedown/pivot pins are machined from AISI8620 steel. They are then heat treated and coated according to mil-spec standards for enhanced durability and corrosion resistance.
The safety and takedown/pivot detents are made from solid hardened stainless steel. This choice of material provides superior corrosion resistance compared to standard carbon steel detents. The magazine button is made from steel. This is a significant upgrade compared to the aluminum buttons found in many commercial LPKs, offering increased durability and resistance to wear.
The Liberty Fighting Trigger is a single-stage trigger designed for a crisp, consistent pull. The hammer and trigger are coated with Nickel PTFE. This reduces friction and increases lubricity for smoother operation.
The pull weight of the Liberty Fighting Trigger averages around 6 lbs. This is without any modifications that would compromise proper function. The black nitride finish is a durable, corrosion-resistant finish applied to various components for longevity.
