Aero Precision 6.5 Grendel M16 / AR-15 Bolt Carrier Group - Black Nitride

In building or upgrading an AR platform rifle, the bolt carrier group is, in many ways, the heart of the rifle. A quality BCG is part of what will make a rifle reliable, so it makes sense that the bolt and its carrier are one of those parts that precision manufacturing has really helped make into a part that can last for high round counts. If you’re looking to upgrade the bolt in your AR, consider the Aero Precision 6.5 Grendel Bolt Carrier Group in Black Nitride.

These are seriously nice bolt carrier groups. Made from 8620 steel, the M16 cut bolt carriers are sure to last basically as long as you care to keep it in the rifle. Additionally, the manufacturer has treated them with a black nitride finish so that the carrier won’t need as much cleaning or lubrication as untreated bolts. The 6.5 Grendel bolt is made from Carpenter 9310 tool steel, so it will also last a long time. This would be a fantastic fit for several kinds of users, but in particular it would make sense for a competition gun in which you’d expect a very high round count, or for precision shooters. This is basically for folks who are building an AR. Finding parts for such a build can be kind of a pain, but this bolt will go a long way to ensuring a quality rifle when you’re done. The carrier is cut to a standard M16 style, so this will work with a large number of other parts. The Aero Precision 6.5 Grendel Bolt Carrier Group in Black Nitride is an excellent bolt carrier group if you want to build a precision AR that will stand up to high round counts or high speed competition shooting.
