Testing reliability and accuracy 7.62x39 in Bear Creek AR- Belom, X-force, New Republic

Published on February 28, 2024
Duration: 14:32

This video tests the reliability and accuracy of a Bear Creek Arsenal AR-15 chambered in 7.62x39 using brass-cased ammunition from Belom, X-Force, and New Republic. The reviewer notes historical reliability issues with the firearm and attempts to zero a 5 MOA Red Dot sight at 50 and 100 yards, ultimately concluding that a scope might be more appropriate due to accuracy limitations.

Quick Summary

Testing a Bear Creek Arsenal AR-15 in 7.62x39 revealed that brass-cased ammunition is essential for reliability, as steel-cased rounds can cause issues. A 5 MOA Red Dot sight proved challenging for accurate shooting at 50 and 100 yards due to its size relative to the target, leading the reviewer to consider a magnified optic for better precision.

Frequently Asked Questions

What are the key considerations for reliability with a 7.62x39 AR-15?

For a 7.62x39 AR-15, especially models like the Bear Creek Arsenal, using brass-cased ammunition is crucial. Steel-cased or lacquer-coated rounds can cause chambering and extraction issues, particularly as the firearm heats up. Also, the bolt design may lack a functional last-shot bolt hold-open.

How does a 5 MOA Red Dot sight perform on 6-inch targets at 50 and 100 yards?

A 5 MOA Red Dot sight can be challenging for precise aiming on 6-inch targets, especially at 50 yards where it covers a significant portion. At 100 yards, the reticle can obscure the entire target, making accurate shot placement and group analysis difficult.

What ammunition brands were tested for reliability and accuracy in the 7.62x39 AR-15?

The video tested Belom, X-Force, and New Republic brands of brass-cased 7.62x39 ammunition. All brands demonstrated reliability in the Bear Creek Arsenal AR-15, though accuracy varied slightly, with New Republic showing a minor advantage at 50 yards.

What are the potential accuracy limitations of a 7.62x39 AR-15 with a Red Dot sight?

The accuracy limitations stem from both the firearm's inherent precision and the optic. A 5 MOA Red Dot can be too large for precise aiming at distance, and the 7.62x39 AR-15 platform itself, especially with historical reliability issues, may not consistently achieve tight groups, suggesting a magnified optic might be better.
