Frequently Asked Questions

What are the key features of the Bear Creek Arsenal 7.62x39mm AR upper?

The Bear Creek Arsenal 7.62x39mm AR upper features a distinctive black and stainless spiral fluted barrel, a handguard with M-LOK slots and QD points, and a Magnetic Particle Inspected (MPI) bolt carrier group. The barrel's fluting aids in weight reduction and cooling.

How does the spiral fluting on the barrel benefit the firearm?

The spiral fluting on the barrel serves two primary purposes: it shaves off weight, making the firearm lighter, and it increases the barrel's surface area. This increased surface area acts like cooling fins, helping the barrel dissipate heat more effectively during firing.

What kind of accuracy can be expected from this 7.62x39mm AR upper?

During accuracy testing at 100 yards, the Bear Creek Arsenal 7.62x39mm upper demonstrated good performance. The SSA by Nosler ammunition achieved the best results, showing the cartridge's potential in an AR platform. Even less expensive options like Wolf Performance performed well.

Is the bolt carrier group (BCG) in this upper noteworthy?

Yes, the BCG is highlighted for its quality. It is MPI inspected, indicating it has undergone testing for internal flaws. The carrier itself has a slick, angular finish and is designed to accommodate the larger 7.62x39mm casing, with an upgraded extractor for reliable extraction.
