First Use Experience

I first tested the Andro Corp Industries AR-15 5.56 NATO 10.3in A2M4 Upper Receiver at my local outdoor range.

Having used other AR uppers in the past, I can confidently say that the Andro Corp Industries upper outperforms many of them in terms of reliability and build quality. It provides a significant step-up from budget-oriented options. It has delivered exceptional performance and durability.
