Let’s Dive into DoubleStar M-16 Full-Auto Bolt Carrier Group (BCG)
The DoubleStar M-16 Full-Auto Bolt Carrier Group (BCG) is a crucial component for any AR-15 rifle build, particularly those aiming for M-16 specifications. DoubleStar promises a complete, reliable, and Mil-Spec coated BCG designed for longevity and consistent performance. It caught my eye as I was piecing together a dedicated range rifle, seeking a BCG that could withstand high round counts and maintain smooth operation.
I was tackling a rebuild of a previously issued rifle where the BCG had seen better days. I needed a replacement that wouldn’t break the bank but wouldn’t compromise on critical features. This particular DoubleStar BCG seemed to strike that balance.
Upon unboxing, the DoubleStar BCG felt solid. The coating appeared even and well-applied, and the individual components seemed precisely machined. The weight felt appropriate, suggesting quality steel and proper construction.
I considered BCGs from Bravo Company Manufacturing (BCM) and Daniel Defense, known for their premium offerings. Ultimately, the DoubleStar won out due to its combination of positive reviews and a more budget-friendly price point for this specific build. My initial excitement was cautiously optimistic. The proof, as they say, would be in the pudding.
Real-World Testing: Putting DoubleStar M-16 Full-Auto Bolt Carrier Group (BCG) to the Test
First Use Experience
My initial test took place at my local outdoor shooting range. I ran approximately 300 rounds of mixed 5.56x45mm ammunition through a rifle equipped with the DoubleStar BCG, focusing on rapid-fire drills and basic accuracy tests. The conditions were relatively dry, with a slight breeze.
The DoubleStar BCG cycled smoothly from the start. I experienced no failures to feed, extract, or eject during this initial range session. The rifle felt consistent and reliable.
There were no immediate issues, but I did notice the coating becoming slightly smoother after the initial break-in period. This wasn’t unexpected, but it’s worth noting for those concerned about aesthetics.
Extended Use & Reliability
After several months of consistent use, the DoubleStar BCG continues to perform reliably. I have now put over 2000 rounds through the rifle with this BCG installed, across multiple range sessions and a carbine course.
The coating has held up surprisingly well, with only minor wear marks in high-friction areas. Cleaning is straightforward, and the BCG requires only standard lubrication to maintain optimal performance. It’s easy to see that DoubleStar made a product that would be easy to maintain.
Compared to the original, well-worn BCG, the DoubleStar provides a noticeable improvement in consistency and smoothness. I haven’t experienced any malfunctions attributable to the BCG itself.
