First Use Experience

I tested the 2A Armament Lightweight Barrel at my local shooting range, focusing on accuracy at 100 yards using various .308 Winchester loads.

The barrel installed seamlessly with my existing upper receiver parts, and the rifle felt noticeably lighter and more balanced.

The first few rounds confirmed my initial impressions: the barrel provided great accuracy for a lightweight option. There were no immediate issues, and the rifle cycled smoothly. After 50 rounds, the barrel began to heat up, but accuracy remained consistent.
