Let’s Talk About Aero Precision AR-15 6mm ARC, 6.5 Grendel Bolt Carrier Group (BCG)
The Aero Precision AR-15 6mm ARC, 6.5 Grendel Bolt Carrier Group (BCG) is a critical component for any AR-15 build chambered in these calibers. It’s more than just a part; it’s the heart of your rifle’s cycling system. Aero Precision is well-regarded for producing high-quality AR components, and this BCG aims to deliver reliability and performance. It boasts features like an M16-cut carrier, a durable nitride finish, and a Carpenter 158 tool steel bolt.
I was looking to build a precision AR-15 in 6.5 Grendel specifically for longer-range shooting and hunting. The reliability of the BCG is paramount, and I needed one designed specifically for the unique dimensions of the 6.5 Grendel cartridge. This one seemed like a great option, based on brand reputation and material specs.
Upon unboxing, the Aero Precision BCG had a sleek, professional appearance, with a smooth, dark black nitride finish. The weight felt substantial, inspiring confidence in the material quality. The machining looked precise and clean, no obvious imperfections.
I considered BCGs from Brownells and Toolcraft, both solid choices with good reputations. I ultimately chose the Aero Precision due to its specific design for 6mm ARC and 6.5 Grendel, coupled with the black nitride finish for corrosion resistance and ease of cleaning. The price point was also competitive.
My first impression was one of excitement; this appeared to be a high-quality, well-made component that would enhance the performance of my AR-15 build. I was eager to get it installed and tested at the range.
Real-World Testing: Putting Aero Precision AR-15 6mm ARC, 6.5 Grendel Bolt Carrier Group (BCG) to the Test
First Use Experience
I tested the Aero Precision AR-15 6mm ARC, 6.5 Grendel Bolt Carrier Group (BCG) at an outdoor shooting range on a clear, sunny day. I used it in my newly assembled 6.5 Grendel AR-15, firing a variety of ammunition from different manufacturers to assess its reliability. The testing environment was relatively clean, with only minor wind and dust.
The BCG performed flawlessly right out of the gate, with no failures to feed, extract, or eject. The cycling action felt smooth and consistent. There were no noticeable hiccups or issues during the first range session.
The installation and initial operation were straightforward, as the Aero Precision BCG dropped right into my AR-15 upper receiver with no need for adjustments or modifications. The smooth nitride finish seemed to contribute to the slick cycling. I was pleasantly surprised by how well it ran from the very first shot.
