Buffer weight broke not even a full magazine - Strike Industries PDW Stabilizer

I purchased a Strike Industries PDW Stock from Optics Planet. I am writing to express my dissatisfaction with this product, I was disappointed to find that this product did not meet my expectations, particularly given the considerable time and effort I invested in building a custom rifle with high-quality components from various manufacturers. My goal was to create a rifle that combined luxury and performance. However, when I took my completed build to the range for testing, I was dismayed to encounter a series of problems that ultimately led to a catastrophic failure. During a 30-round magazine test, the BCG jammed halfway through, causing a severe malfunction. Further inspection revealed that the Buffer Weight had broken apart, releasing internal granules and damaging the red plastic component. As someone with extensive experience with firearms, I am shocked by the severity of this product's failure, which raises serious concerns about its reliability in real-world situation
